class: Page

  • extends: [EventEmitter]

Page provides methods to interact with a single tab in a [Browser], or an extension background page in Chromium. One [Browser] instance might have multiple [Page] instances.

This example creates a page, navigates it to a URL, and then saves a screenshot:

const { webkit } = require('playwright');  // Or 'chromium' or 'firefox'.

(async () => {
  const browser = await webkit.launch();
  const context = await browser.newContext();
  const page = await context.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'screenshot.png'});
  await browser.close();
})();
import com.microsoft.playwright.*;

public class Example {
  public static void main(String[] args) {
    try (Playwright playwright = Playwright.create()) {
      BrowserType webkit = playwright.webkit();
      Browser browser = webkit.launch();
      BrowserContext context = browser.newContext();
      Page page = context.newPage();
      page.navigate("https://example.com");
      page.screenshot(new Page.ScreenshotOptions().setPath(Paths.get("screenshot.png")));
      browser.close();
    }
  }
}
import asyncio
from playwright.async_api import async_playwright

async def run(playwright):
    webkit = playwright.webkit
    browser = await webkit.launch()
    context = await browser.new_context()
    page = await context.new_page()
    await page.goto("https://example.com")
    await page.screenshot(path="screenshot.png")
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)
asyncio.run(main())
from playwright.sync_api import sync_playwright

def run(playwright):
    webkit = playwright.webkit
    browser = webkit.launch()
    context = browser.new_context()
    page = context.new_page()
    page.goto("https://example.com")
    page.screenshot(path="screenshot.png")
    browser.close()

with sync_playwright() as playwright:
    run(playwright)
using Microsoft.Playwright;
using System.Threading.Tasks;

class PageExamples
{
    public static async Task Run()
    {
        using var playwright = await Playwright.CreateAsync();
        await using var browser = await playwright.Webkit.LaunchAsync();
        var page = await browser.NewPageAsync();
        await page.GotoAsync("https://www.theverge.com");
        await page.ScreenshotAsync(new PageScreenshotOptions { Path = "theverge.png" });
    }
}

The Page class emits various events (described below) which can be handled using any of Node's native EventEmitter methods, such as on, once or removeListener.

This example logs a message for a single page load event:

page.once('load', () => console.log('Page loaded!'));
page.onLoad(p -> System.out.println("Page loaded!"));
page.once("load", lambda: print("page loaded!"))
page.Load += (_, _) => Console.WriteLine("Page loaded!");

To unsubscribe from events use the removeListener method:

function logRequest(interceptedRequest) {
  console.log('A request was made:', interceptedRequest.url());
}
page.on('request', logRequest);
// Sometime later...
page.removeListener('request', logRequest);
Consumer<Request> logRequest = interceptedRequest -> {
  System.out.println("A request was made: " + interceptedRequest.url());
};
page.onRequest(logRequest);
// Sometime later...
page.offRequest(logRequest);
def log_request(intercepted_request):
    print("a request was made:", intercepted_request.url)
page.on("request", log_request)
# sometime later...
page.remove_listener("request", log_request)
void PageLoadHandler(object _, IPage p) {
    Console.WriteLine("Page loaded!");
};

page.Load += PageLoadHandler;
// Do some work...
page.Load -= PageLoadHandler;

event: Page.close

  • argument: <[Page]>

Emitted when the page closes.

event: Page.console

  • langs:
    • alias-java: consoleMessage
  • argument: <[ConsoleMessage]>

Emitted when JavaScript within the page calls one of console API methods, e.g. console.log or console.dir. Also emitted if the page throws an error or a warning.

The arguments passed into console.log appear as arguments on the event handler.

An example of handling console event:

page.on('console', async msg => {
  for (let i = 0; i < msg.args().length; ++i)
    console.log(`${i}: ${await msg.args()[i].jsonValue()}`);
});
await page.evaluate(() => console.log('hello', 5, {foo: 'bar'}));
page.onConsoleMessage(msg -> {
  for (int i = 0; i < msg.args().size(); ++i)
    System.out.println(i + ": " + msg.args().get(i).jsonValue());
});
page.evaluate("() => console.log('hello', 5, {foo: 'bar'})");
async def print_args(msg):
    for arg in msg.args:
        print(await arg.json_value())

page.on("console", print_args)
await page.evaluate("console.log('hello', 5, {foo: 'bar'})")
def print_args(msg):
    for arg in msg.args:
        print(arg.json_value())

page.on("console", print_args)
page.evaluate("console.log('hello', 5, {foo: 'bar'})")
page.Console += async (_, msg) =>
{
    foreach (var arg in msg.Args)
        Console.WriteLine(await arg.JsonValueAsync<object>());
};

await page.EvaluateAsync("console.log('hello', 5, { foo: 'bar' })");

event: Page.crash

  • argument: <[Page]>

Emitted when the page crashes. Browser pages might crash if they try to allocate too much memory. When the page crashes, ongoing and subsequent operations will throw.

The most common way to deal with crashes is to catch an exception:

try {
  // Crash might happen during a click.
  await page.click('button');
  // Or while waiting for an event.
  await page.waitForEvent('popup');
} catch (e) {
  // When the page crashes, exception message contains 'crash'.
}
try {
  // Crash might happen during a click.
  page.click("button");
  // Or while waiting for an event.
  page.waitForPopup(() -> {});
} catch (PlaywrightException e) {
  // When the page crashes, exception message contains "crash".
}
try:
    # crash might happen during a click.
    await page.click("button")
    # or while waiting for an event.
    await page.wait_for_event("popup")
except Error as e:
    # when the page crashes, exception message contains "crash".
try:
    # crash might happen during a click.
    page.click("button")
    # or while waiting for an event.
    page.wait_for_event("popup")
except Error as e:
    # when the page crashes, exception message contains "crash".
try {
  // Crash might happen during a click.
  await page.ClickAsync("button");
  // Or while waiting for an event.
  await page.WaitForPopup();
} catch (PlaywrightException e) {
  // When the page crashes, exception message contains "crash".
}

event: Page.dialog

  • argument: <[Dialog]>

Emitted when a JavaScript dialog appears, such as alert, prompt, confirm or beforeunload. Listener must either [method: Dialog.accept] or [method: Dialog.dismiss] the dialog - otherwise the page will freeze waiting for the dialog, and actions like click will never finish.

:::note When no [event: Page.dialog] listeners are present, all dialogs are automatically dismissed. :::

event: Page.DOMContentLoaded

  • argument: <[Page]>

Emitted when the JavaScript DOMContentLoaded event is dispatched.

event: Page.download

  • argument: <[Download]>

Emitted when attachment download started. User can access basic file operations on downloaded content via the passed [Download] instance.

:::note Browser context must be created with the [option: acceptDownloads] set to true when user needs access to the downloaded content. If [option: acceptDownloads] is not set, download events are emitted, but the actual download is not performed and user has no access to the downloaded files. :::

event: Page.fileChooser

  • argument: <[FileChooser]>

Emitted when a file chooser is supposed to appear, such as after clicking the <input type=file>. Playwright can respond to it via setting the input files using [method: FileChooser.setFiles] that can be uploaded after that.

page.on('filechooser', async (fileChooser) => {
  await fileChooser.setFiles('/tmp/myfile.pdf');
});
page.onFileChooser(fileChooser -> {
  fileChooser.setFiles(Paths.get("/tmp/myfile.pdf"));
});
page.on("filechooser", lambda file_chooser: file_chooser.set_files("/tmp/myfile.pdf"))
page.FileChooser += (_, fileChooser) =>
{
    fileChooser.SetFilesAsync(@"C:\temp\myfile.pdf");
};

event: Page.frameAttached

  • argument: <[Frame]>

Emitted when a frame is attached.

event: Page.frameDetached

  • argument: <[Frame]>

Emitted when a frame is detached.

event: Page.frameNavigated

  • argument: <[Frame]>

Emitted when a frame is navigated to a new url.

event: Page.load

  • argument: <[Page]>

Emitted when the JavaScript load event is dispatched.

event: Page.pageError

  • argument: <[Error]>

Emitted when an uncaught exception happens within the page.

event: Page.pageError

  • langs: csharp, java
  • argument: <[string]>

event: Page.popup

  • argument: <[Page]>

Emitted when the page opens a new tab or window. This event is emitted in addition to the [event: BrowserContext.page], but only for popups relevant to this page.

The earliest moment that page is available is when it has navigated to the initial url. For example, when opening a popup with window.open('http://example.com'), this event will fire when the network request to "http://example.com" is done and its response has started loading in the popup.

const [popup] = await Promise.all([
  page.waitForEvent('popup'),
  page.evaluate(() => window.open('https://example.com')),
]);
console.log(await popup.evaluate('location.href'));
Page popup = page.waitForPopup(() -> {
  page.evaluate("() => window.open('https://example.com')");
});
System.out.println(popup.evaluate("location.href"));
async with page.expect_event("popup") as page_info:
    page.evaluate("window.open('https://example.com')")
popup = await page_info.value
print(await popup.evaluate("location.href"))
with page.expect_event("popup") as page_info:
    page.evaluate("window.open('https://example.com')")
popup = page_info.value
print(popup.evaluate("location.href"))
var popup = await page.RunAndWaitForPopupAsync(async () =>
{
    await page.EvaluateAsync("() => window.open('https://microsoft.com')");
});
Console.WriteLine(await popup.EvaluateAsync<string>("location.href"));

:::note Use [method: Page.waitForLoadState] to wait until the page gets to a particular state (you should not need it in most cases). :::

event: Page.request

  • argument: <[Request]>

Emitted when a page issues a request. The [request] object is read-only. In order to intercept and mutate requests, see [method: Page.route] or [method: BrowserContext.route].

event: Page.requestFailed

  • argument: <[Request]>

Emitted when a request fails, for example by timing out.

:::note HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with [event: Page.requestFinished] event and not with [event: Page.requestFailed]. A request will only be considered failed when the client cannot get an HTTP response from the server, e.g. due to network error net::ERR_FAILED. :::

event: Page.requestFinished

  • argument: <[Request]>

Emitted when a request finishes successfully after downloading the response body. For a successful response, the sequence of events is request, response and requestfinished.

event: Page.response

  • argument: <[Response]>

Emitted when [response] status and headers are received for a request. For a successful response, the sequence of events is request, response and requestfinished.

event: Page.webSocket

  • argument: <[WebSocket]>

Emitted when [WebSocket] request is sent.

event: Page.worker

  • argument: <[Worker]>

Emitted when a dedicated WebWorker is spawned by the page.

property: Page.accessibility

  • langs: csharp, js, python
  • type: <[Accessibility]>

async method: Page.addInitScript

Adds a script which would be evaluated in one of the following scenarios:

  • Whenever the page is navigated.
  • Whenever the child frame is attached or navigated. In this case, the script is evaluated in the context of the newly attached frame.

The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed Math.random.

An example of overriding Math.random before the page loads:

// preload.js
Math.random = () => 42;
// In your playwright script, assuming the preload.js file is in same directory
await page.addInitScript({ path: './preload.js' });
// In your playwright script, assuming the preload.js file is in same directory
page.addInitScript(Paths.get("./preload.js"));
# in your playwright script, assuming the preload.js file is in same directory
await page.add_init_script(path="./preload.js")
# in your playwright script, assuming the preload.js file is in same directory
page.add_init_script(path="./preload.js")
await page.AddInitScriptAsync(new PageAddInitScriptOption { ScriptPath = "./preload.js" });

:::note The order of evaluation of multiple scripts installed via [method: BrowserContext.addInitScript] and [method: Page.addInitScript] is not defined. :::

param: Page.addInitScript.script

  • langs: js
  • script <[function]|[string]|[Object]>
    • path <[path]> Path to the JavaScript file. If path is a relative path, then it is resolved relative to the current working directory. Optional.
    • content <[string]> Raw script content. Optional.

Optional argument to pass to [param: script] (only supported when passing a function).

async method: Page.addScriptTag

  • returns: <[ElementHandle]>

Adds a <script> tag into the page with the desired url or content. Returns the added tag when the script's onload fires or when the script content was injected into frame.

Shortcut for main frame's [method: Frame.addScriptTag].

option: Page.addScriptTag.url

  • url <[string]>

URL of a script to be added.

option: Page.addScriptTag.path

  • path <[path]>

option: Page.addScriptTag.content

  • content <[string]>

Raw JavaScript content to be injected into frame.

option: Page.addScriptTag.type

  • type <[string]>

Script type. Use 'module' in order to load a Javascript ES6 module. See script for more details.

async method: Page.addStyleTag

  • returns: <[ElementHandle]>

Adds a <link rel="stylesheet"> tag into the page with the desired url or a <style type="text/css"> tag with the content. Returns the added tag when the stylesheet's onload fires or when the CSS content was injected into frame.

Shortcut for main frame's [method: Frame.addStyleTag].

option: Page.addStyleTag.url

  • url <[string]>

URL of the <link> tag.

option: Page.addStyleTag.path

  • path <[path]>

Path to the CSS file to be injected into frame. If path is a relative path, then it is resolved relative to the current working directory.

async method: Page.bringToFront

Brings page to front (activates tab).

async method: Page.check

This method checks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
  3. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  4. Scroll the element into view if needed.
  5. Use [property: Page.mouse] to click in the center of the element.
  6. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.
  7. Ensure that the element is now checked. If not, this method throws.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

Shortcut for main frame's [method: Frame.check].

param: Page.check.selector = %%-input-selector-%%

option: Page.check.force = %%-input-force-%%

option: Page.check.noWaitAfter = %%-input-no-wait-after-%%

option: Page.check.position = %%-input-position-%%

option: Page.check.strict = %%-input-strict-%%

option: Page.check.timeout = %%-input-timeout-%%

option: Page.check.trial = %%-input-trial-%%

async method: Page.click

This method clicks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.mouse] to click in the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

Shortcut for main frame's [method: Frame.click].

param: Page.click.selector = %%-input-selector-%%

option: Page.click.button = %%-input-button-%%

option: Page.click.clickCount = %%-input-click-count-%%

option: Page.click.delay = %%-input-down-up-delay-%%

option: Page.click.force = %%-input-force-%%

option: Page.click.modifiers = %%-input-modifiers-%%

option: Page.click.noWaitAfter = %%-input-no-wait-after-%%

option: Page.click.position = %%-input-position-%%

option: Page.click.strict = %%-input-strict-%%

option: Page.click.timeout = %%-input-timeout-%%

option: Page.click.trial = %%-input-trial-%%

async method: Page.close

If [option: runBeforeUnload] is false, does not run any unload handlers and waits for the page to be closed. If [option: runBeforeUnload] is true the method will run unload handlers, but will not wait for the page to close.

By default, page.close() does not run beforeunload handlers.

:::note if [option: runBeforeUnload] is passed as true, a beforeunload dialog might be summoned and should be handled manually via [event: Page.dialog] event. :::

option: Page.close.runBeforeUnload

  • runBeforeUnload <[boolean]>

Defaults to false. Whether to run the before unload page handlers.

async method: Page.content

  • returns: <[string]>

Gets the full HTML contents of the page, including the doctype.

method: Page.context

  • returns: <[BrowserContext]>

Get the browser context that the page belongs to.

property: Page.coverage

  • langs: js
  • type: <[Coverage]>

:::note Only available for Chromium atm. :::

Browser-specific Coverage implementation. See Coverage for more details.

async method: Page.dblclick

  • langs:
    • alias-csharp: DblClickAsync

This method double clicks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.mouse] to double click in the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set. Note that if the first click of the dblclick() triggers a navigation event, this method will throw.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

:::note page.dblclick() dispatches two click events and a single dblclick event. :::

Shortcut for main frame's [method: Frame.dblclick].

param: Page.dblclick.selector = %%-input-selector-%%

option: Page.dblclick.button = %%-input-button-%%

option: Page.dblclick.force = %%-input-force-%%

option: Page.dblclick.strict = %%-input-strict-%%

option: Page.dblclick.timeout = %%-input-timeout-%%

option: Page.dblclick.trial = %%-input-trial-%%

async method: Page.dispatchEvent

The snippet below dispatches the click event on the element. Regardless of the visibility state of the element, click is dispatched. This is equivalent to calling element.click().

await page.dispatchEvent('button#submit', 'click');
page.dispatchEvent("button#submit", "click");
await page.dispatch_event("button#submit", "click")
page.dispatch_event("button#submit", "click")
await page.DispatchEventAsync("button#submit", "click");

Under the hood, it creates an instance of an event based on the given [param: type], initializes it with [param: eventInit] properties and dispatches it on the element. Events are composed, cancelable and bubble by default.

Since [param: eventInit] is event-specific, please refer to the events documentation for the lists of initial properties:

You can also specify JSHandle as the property value if you want live objects to be passed into the event:

// Note you can only create DataTransfer in Chromium and Firefox
const dataTransfer = await page.evaluateHandle(() => new DataTransfer());
await page.dispatchEvent('#source', 'dragstart', { dataTransfer });
// Note you can only create DataTransfer in Chromium and Firefox
JSHandle dataTransfer = page.evaluateHandle("() => new DataTransfer()");
Map<String, Object> arg = new HashMap<>();
arg.put("dataTransfer", dataTransfer);
page.dispatchEvent("#source", "dragstart", arg);
# note you can only create data_transfer in chromium and firefox
data_transfer = await page.evaluate_handle("new DataTransfer()")
await page.dispatch_event("#source", "dragstart", { "dataTransfer": data_transfer })
# note you can only create data_transfer in chromium and firefox
data_transfer = page.evaluate_handle("new DataTransfer()")
page.dispatch_event("#source", "dragstart", { "dataTransfer": data_transfer })
var dataTransfer = await page.EvaluateHandleAsync("() => new DataTransfer()");
await page.DispatchEventAsync("#source", "dragstart", new { dataTransfer });

param: Page.dispatchEvent.selector = %%-input-selector-%%

param: Page.dispatchEvent.type

  • type <[string]>

DOM event type: "click", "dragstart", etc.

param: Page.dispatchEvent.eventInit

  • eventInit <[EvaluationArgument]>

async method: Page.evalOnSelector

  • langs:
    • alias-python: eval_on_selector
    • alias-js: $eval
  • returns: <[Serializable]>

The method finds an element matching the specified selector within the page and passes it as a first argument to [param: expression]. If no elements match the selector, the method throws an error. Returns the value of [param: expression].

If [param: expression] returns a [Promise], then [method: Page.evalOnSelector] would wait for the promise to resolve and return its value.

Examples:

const searchValue = await page.$eval('#search', el => el.value);
const preloadHref = await page.$eval('link[rel=preload]', el => el.href);
const html = await page.$eval('.main-container', (e, suffix) => e.outerHTML + suffix, 'hello');
// In TypeScript, this example requires an explicit type annotation (HTMLLinkElement) on el:
const preloadHrefTS = await page.$eval('link[rel=preload]', (el: HTMLLinkElement) => el.href);
String searchValue = (String) page.evalOnSelector("#search", "el => el.value");
String preloadHref = (String) page.evalOnSelector("link[rel=preload]", "el => el.href");
String html = (String) page.evalOnSelector(".main-container", "(e, suffix) => e.outerHTML + suffix", "hello");
search_value = await page.eval_on_selector("#search", "el => el.value")
preload_href = await page.eval_on_selector("link[rel=preload]", "el => el.href")
html = await page.eval_on_selector(".main-container", "(e, suffix) => e.outer_html + suffix", "hello")
search_value = page.eval_on_selector("#search", "el => el.value")
preload_href = page.eval_on_selector("link[rel=preload]", "el => el.href")
html = page.eval_on_selector(".main-container", "(e, suffix) => e.outer_html + suffix", "hello")
var searchValue = await page.EvalOnSelectorAsync<string>("#search", "el => el.value");
var preloadHref = await page.EvalOnSelectorAsync<string>("link[rel=preload]", "el => el.href");
var html = await page.EvalOnSelectorAsync(".main-container", "(e, suffix) => e.outerHTML + suffix", "hello");

Shortcut for main frame's [method: Frame.evalOnSelector].

param: Page.evalOnSelector.selector = %%-query-selector-%%

param: Page.evalOnSelector.expression = %%-evaluate-expression-%%

param: Page.evalOnSelector.arg

  • arg <[EvaluationArgument]>

Optional argument to pass to [param: expression].

option: Page.evalOnSelector.strict = %%-input-strict-%%

async method: Page.evalOnSelectorAll

  • langs:
    • alias-python: eval_on_selector_all
    • alias-js: $$eval
  • returns: <[Serializable]>

The method finds all elements matching the specified selector within the page and passes an array of matched elements as a first argument to [param: expression]. Returns the result of [param: expression] invocation.

If [param: expression] returns a [Promise], then [method: Page.evalOnSelectorAll] would wait for the promise to resolve and return its value.

Examples:

const divCounts = await page.$$eval('div', (divs, min) => divs.length >= min, 10);
boolean divCounts = (boolean) page.evalOnSelectorAll("div", "(divs, min) => divs.length >= min", 10);
div_counts = await page.eval_on_selector_all("div", "(divs, min) => divs.length >= min", 10)
div_counts = page.eval_on_selector_all("div", "(divs, min) => divs.length >= min", 10)
var divsCount = await page.EvalOnSelectorAllAsync<bool>("div", "(divs, min) => divs.length >= min", 10);

param: Page.evalOnSelectorAll.selector = %%-query-selector-%%

param: Page.evalOnSelectorAll.expression = %%-evaluate-expression-%%

param: Page.evalOnSelectorAll.arg

  • arg <[EvaluationArgument]>

Optional argument to pass to [param: expression].

async method: Page.evaluate

  • returns: <[Serializable]>

Returns the value of the [param: expression] invocation.

If the function passed to the [method: Page.evaluate] returns a [Promise], then [method: Page.evaluate] would wait for the promise to resolve and return its value.

If the function passed to the [method: Page.evaluate] returns a non-[Serializable] value, then [method: Page.evaluate] resolves to undefined. Playwright also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity.

Passing argument to [param: expression]:

const result = await page.evaluate(([x, y]) => {
  return Promise.resolve(x * y);
}, [7, 8]);
console.log(result); // prints "56"
Object result = page.evaluate("([x, y]) => {\n" +
  "  return Promise.resolve(x * y);\n" +
  "}", Arrays.asList(7, 8));
System.out.println(result); // prints "56"
result = await page.evaluate("([x, y]) => Promise.resolve(x * y)", [7, 8])
print(result) # prints "56"
result = page.evaluate("([x, y]) => Promise.resolve(x * y)", [7, 8])
print(result) # prints "56"
var result = await page.EvaluateAsync<int>("([x, y]) => Promise.resolve(x * y)", new[] { 7, 8 });
Console.WriteLine(result);

A string can also be passed in instead of a function:

console.log(await page.evaluate('1 + 2')); // prints "3"
const x = 10;
console.log(await page.evaluate(`1 + ${x}`)); // prints "11"
System.out.println(page.evaluate("1 + 2")); // prints "3"
print(await page.evaluate("1 + 2")) # prints "3"
x = 10
print(await page.evaluate(f"1 + {x}")) # prints "11"
print(page.evaluate("1 + 2")) # prints "3"
x = 10
print(page.evaluate(f"1 + {x}")) # prints "11"
Console.WriteLine(await page.EvaluateAsync<int>("1 + 2")); // prints "3"

[ElementHandle] instances can be passed as an argument to the [method: Page.evaluate]:

const bodyHandle = await page.$('body');
const html = await page.evaluate(([body, suffix]) => body.innerHTML + suffix, [bodyHandle, 'hello']);
await bodyHandle.dispose();
ElementHandle bodyHandle = page.querySelector("body");
String html = (String) page.evaluate("([body, suffix]) => body.innerHTML + suffix", Arrays.asList(bodyHandle, "hello"));
bodyHandle.dispose();
body_handle = await page.query_selector("body")

body_handle.dispose()
var bodyHandle = await page.QuerySelectorAsync("body");
var html = await page.EvaluateAsync<string>("([body, suffix]) => body.innerHTML + suffix", new object [] { bodyHandle, "hello" });
await bodyHandle.DisposeAsync();

Shortcut for main frame's [method: Frame.evaluate].

param: Page.evaluate.expression = %%-evaluate-expression-%%

param: Page.evaluate.arg

  • arg <[EvaluationArgument]>

Optional argument to pass to [param: expression].

async method: Page.evaluateHandle

  • returns: <[JSHandle]>

Returns the value of the [param: expression] invocation as a [JSHandle].

The only difference between [method: Page.evaluate] and [method: Page.evaluateHandle] is that [method: Page.evaluateHandle] returns [JSHandle].

If the function passed to the [method: Page.evaluateHandle] returns a [Promise], then [method: Page.evaluateHandle] would wait for the promise to resolve and return its value.

const aWindowHandle = await page.evaluateHandle(() => Promise.resolve(window));
aWindowHandle; // Handle for the window object.
// Handle for the window object.
JSHandle aWindowHandle = page.evaluateHandle("() => Promise.resolve(window)");
a_window_handle = await page.evaluate_handle("Promise.resolve(window)")
a_window_handle # handle for the window object.
a_window_handle = page.evaluate_handle("Promise.resolve(window)")
a_window_handle # handle for the window object.
// Handle for the window object.
var aWindowHandle = await page.EvaluateHandleAsync("() => Promise.resolve(window)");

A string can also be passed in instead of a function:

const aHandle = await page.evaluateHandle('document'); // Handle for the 'document'
JSHandle aHandle = page.evaluateHandle("document"); // Handle for the "document".
a_handle = await page.evaluate_handle("document") # handle for the "document"
a_handle = page.evaluate_handle("document") # handle for the "document"
var docHandle = await page.EvalueHandleAsync("document"); // Handle for the `document`

[JSHandle] instances can be passed as an argument to the [method: Page.evaluateHandle]:

const aHandle = await page.evaluateHandle(() => document.body);
const resultHandle = await page.evaluateHandle(body => body.innerHTML, aHandle);
console.log(await resultHandle.jsonValue());
await resultHandle.dispose();
JSHandle aHandle = page.evaluateHandle("() => document.body");

async method: Page.exposeBinding

The method adds a function called [param: name] on the window object of every frame in this page. When called, the function executes [param: callback] and returns a [Promise] which resolves to the return value of [param: callback]. If the [param: callback] returns a [Promise], it will be awaited.

The first argument of the [param: callback] function contains information about the caller: { browserContext: BrowserContext, page: Page, frame: Frame }.

See [method: BrowserContext.exposeBinding] for the context-wide version.

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.mouse] to hover over the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless noWaitAfter option is set.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

async method: Page.press

Focuses the element, and then uses [method: Keyboard.down] and [method: Keyboard.up].

[param: key] can specify the intended keyboardEvent.key value or a single character to generate the text for. A superset of the [param: key] values can be found here. Examples of the keys are:

Following modification shortcuts are also supported: Shift, Control, Alt, Meta, ShiftLeft.

Holding down Shift will type the text that corresponds to the [param: key] in the upper case.

If [param: key] is a single character, it is case-sensitive, so the values a and A will generate different respective texts.

Shortcuts such as key: "Control+o" or key: "Control+Shift+T" are supported as well. When specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.

property: Page.request

  • langs: js
  • type: <[APIRequestContext]>

API testing helper associated with this page. Requests made with this API will use page cookies.

async method: Page.route

Routing provides the capability to modify network requests that are made by a page.

Once routing is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.

:::note The handler will only be called for the first url if the response is a redirect. :::

:::note [method: Page.route] will not intercept requests intercepted by Service Worker. See this issue. We recommend disabling Service Workers when using request interception. Via await context.addInitScript(() => delete window.navigator.serviceWorker); :::

An example of a naive handler that aborts all image requests:

const page = await browser.newPage();
await page.route('**/*.{png,jpg,jpeg}', route => route.abort());
await page.goto('https://example.com');
await browser.close();
Page page = browser.newPage();
page.route("**/*.{png,jpg,jpeg}", route -> route.abort());
page.navigate("https://example.com");
browser.close();
page = await browser.new_page()
await page.route("**/*.{png,jpg,jpeg}", lambda route: route.abort())
await page.goto("https://example.com")
await browser.close()
page = browser.new_page()
page.route("**/*.{png,jpg,jpeg}", lambda route: route.abort())
page.goto("https://example.com")
browser.close()
var page = await browser.NewPageAsync();
await page.RouteAsync("**/*.{png,jpg,jpeg}", async r => await r.AbortAsync());
await page.GotoAsync("https://www.microsoft.com");

or the same snippet using a regex pattern instead:

const page = await browser.newPage();
await page.route(/(\.png$)|(\.jpg$)/, route => route.abort());
await page.goto('https://example.com');
await browser.close();
Page page = browser.newPage();
page.route(Pattern.compile("(\\.png$)|(\\.jpg$)"),route -> route.abort());
page.navigate("https://example.com");
browser.close();
page = await browser.new_page()
await page.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort())
await page.goto("https://example.com")
await browser.close()
page = browser.new_page()
page.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort())
page.goto("https://example.com")
browser.close()
var page = await browser.NewPageAsync();
await page.RouteAsync(new Regex("(\\.png$)|(\\.jpg$)"), async r => await r.AbortAsync());
await page.GotoAsync("https://www.microsoft.com");

It is possible to examine the request to decide the route action. For example, mocking all requests that contain some post data, and leaving all other requests as is:

await page.route('/api/**', route => {
  if (route.request().postData().includes('my-string'))
    route.fulfill({ body: 'mocked-data' });
  else
    route.continue();
});
page.route("/api/**", route -> {
  if (route.request().postData().contains("my-string"))
    route.fulfill(new Route.FulfillOptions().setBody("mocked-data"));
  else
    route.resume();
});
def handle_route(route):
  if ("my-string" in route.request.post_data)
    route.fulfill(body="mocked-data")
  else
    route.continue_()
await page.route("/api/**", handle_route)
def handle_route(route):
  if ("my-string" in route.request.post_data)
    route.fulfill(body="mocked-data")
  else
    route.continue_()
page.route("/api/**", handle_route)
await page.RouteAsync("/api/**", async r =>
{
  if (r.Request.PostData.Contains("my-string"))
      await r.FulfillAsync(new RouteFulfillOptions { Body = "mocked-data" });
  else
      await r.ContinueAsync();
});

Page routes take precedence over browser context routes (set up with [method: BrowserContext.route]) when request matches both handlers.

To remove a route with its handler you can use [method: Page.unroute].

async method: Page.setChecked

This method checks or unchecks an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Ensure that matched element is a checkbox or a radio input. If not, this method throws.
  3. If the element already has the right checked state, this method returns immediately.
  4. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  5. Scroll the element into view if needed.
  6. Use [property: Page.mouse] to click in the center of the element.
  7. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.
  8. Ensure that the element is now checked or unchecked. If not, this method throws.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

async method: Page.tap

This method taps an element matching [param: selector] by performing the following steps:

  1. Find an element matching [param: selector]. If there is none, wait until a matching element is attached to the DOM.
  2. Wait for actionability checks on the matched element, unless [option: force] option is set. If the element is detached during the checks, the whole action is retried.
  3. Scroll the element into view if needed.
  4. Use [property: Page.touchscreen] to tap the center of the element, or the specified [option: position].
  5. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.

When all steps combined have not finished during the specified [option: timeout], this method throws a [TimeoutError]. Passing zero timeout disables this.

  • langs:
    • alias-python: expect_navigation
    • alias-csharp: RunAndWaitForNavigation
  • returns: <[null]|[Response]>

Waits for the main frame navigation and returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect. In case of navigation to a different anchor or navigation due to History API usage, the navigation will resolve with null.

This resolves when the page navigates to a new URL or reloads. It is useful for when you run code which will indirectly cause the page to navigate. e.g. The click target has an onclick handler that triggers navigation from a setTimeout. Consider this example:

const [response] = await Promise.all([
  page.waitForNavigation(), // The promise resolves after navigation has finished
  page.click('a.delayed-navigation'), // Clicking the link will indirectly cause a navigation
]);
// The method returns after navigation has finished

  page.click("a.delayed-navigation"); // Clicking the link will indirectly cause a navigation
});

param: Page.waitForResponse.action = %%-csharp-wait-for-event-action-%%

param: Page.waitForResponse.urlOrPredicate

  • urlOrPredicate <[string]|[RegExp]|[function][Response]:[boolean]>

Request URL string, regex or predicate receiving [Response] object. When a [option: baseURL] via the context options was provided and the passed URL is a path, it gets merged via the new URL() constructor.

param: Page.waitForResponse.urlOrPredicate

  • langs: js
  • urlOrPredicate <[string]|[RegExp]|[function][Response]:[boolean]|[Promise]<[boolean]>>

Request URL string, regex or predicate receiving [Response] object. When a [option: baseURL] via the context options was provided and the passed URL is a path, it gets merged via the new URL() constructor.

option: Page.waitForResponse.timeout

  • timeout <[float]>

Maximum wait time in milliseconds, defaults to 30 seconds, pass 0 to disable the timeout. The default value can be changed by using the [method: BrowserContext.setDefaultTimeout] or [method: Page.setDefaultTimeout] methods.

async method: Page.waitForSelector

  • returns: <[null]|[ElementHandle]>

Returns when element specified by selector satisfies [option: state] option. Returns null if waiting for hidden or detached.

Wait for the [param: selector] to satisfy [option: state] option (either appear/disappear from dom, or become visible/hidden). If at the moment of calling the method [param: selector] already satisfies the condition, the method will return immediately. If the selector doesn't satisfy the condition for the [option: timeout] milliseconds, the function will throw.

This method works across navigations:

async method: Page.waitForWebSocket

  • langs: java, python, csharp
    • alias-python: expect_websocket
    • alias-csharp: RunAndWaitForWebSocket
  • returns: <[WebSocket]>

Performs action and waits for a new [WebSocket]. If predicate is provided, it passes [WebSocket] value into the predicate function and waits for predicate(webSocket) to return a truthy value. Will throw an error if the page is closed before the WebSocket event is fired.

option: Page.waitForWebSocket.predicate =

async method: Page.waitForWorker

  • langs: java, python, csharp
    • alias-python: expect_worker
    • alias-csharp: RunAndWaitForWorker
  • returns: <[Worker]>

Performs action and waits for a new [Worker]. If predicate is provided, it passes [Worker] value into the predicate function and waits for predicate(worker) to return a truthy value. Will throw an error if the page is closed before the worker event is fired.

option: Page.waitForWorker.predicate =

  • predicate <[function][Worker]:[boolean]>

Receives the [Worker] object and resolves to truthy value when the waiting should resolve.

option: Page.waitForWorker.timeout = %%-wait-for-event-timeout-%%

method: Page.workers

  • returns: <[Array]<[Worker]>>

This method returns all of the dedicated WebWorkers associated with the page.
