class: ElementHandle

  • extends: [JSHandle]

ElementHandle represents an in-page DOM element. ElementHandles can be created with the [method: Page.querySelector] method.

:::caution Discouraged The use of ElementHandle is discouraged, use [Locator] objects and web-first assertions instead. :::

const hrefElement = await page.$('a');
await hrefElement.click();
ElementHandle hrefElement = page.querySelector("a");
hrefElement.click();
href_element = await page.query_selector("a")
await href_element.click()
href_element = page.query_selector("a")
href_element.click()
var handle = await page.QuerySelectorAsync("a");
await handle.ClickAsync();

ElementHandle prevents DOM element from garbage collection unless the handle is disposed with [method: JSHandle.dispose]. ElementHandles are auto-disposed when their origin frame gets navigated.

ElementHandle instances can be used as an argument in [method: Page.evalOnSelector] and [method: Page.evaluate] methods.

The difference between the [Locator] and ElementHandle is that the ElementHandle points to a particular element, while [Locator] captures the logic of how to retrieve an element.

In the example below, handle points to a particular DOM element on page. If that element changes text or is used by React to render an entirely different component, handle is still pointing to that very DOM element. This can lead to unexpected behaviors.

const handle = await page.$('text=Submit');
// ...
await handle.hover();
await handle.click();
ElementHandle handle = page.querySelector("text=Submit");
handle.hover();
handle.click();
handle = await page.query_selector("text=Submit")
await handle.hover()
await handle.click()
handle = page.query_selector("text=Submit")
handle.hover()
handle.click()
var handle = await page.QuerySelectorAsync("text=Submit");
await handle.HoverAsync();
await handle.ClickAsync();

With the locator, every time the element is used, up-to-date DOM element is located in the page using the selector. So in the snippet below, underlying DOM element is going to be located twice.

const locator = page.locator('text=Submit');
// ...
await locator.hover();
await locator.click();
Locator locator = page.locator("text=Submit");
locator.hover();
locator.click();
locator = page.locator("text=Submit")
await locator.hover()
await locator.click()
locator = page.locator("text=Submit")
locator.hover()
locator.click()
var locator = page.Locator("text=Submit");
await locator.HoverAsync();
await locator.ClickAsync();

async method: ElementHandle.boundingBox

  • returns: <[null]|[Object]>
    • x <[float]> the x coordinate of the element in pixels.
    • y <[float]> the y coordinate of the element in pixels.
    • width <[float]> the width of the element in pixels.
    • height <[float]> the height of the element in pixels.

This method returns the bounding box of the element, or null if the element is not visible. The bounding box is calculated relative to the main frame viewport - which is usually the same as the browser window.

Scrolling affects the returned bonding box, similarly to Element.getBoundingClientRect. That means x and/or y may be negative.

Elements from child frames return the bounding box relative to the main frame, unlike the Element.getBoundingClientRect.

Assuming the page is static, it is safe to use bounding box coordinates to perform input. For example, the following snippet should click the center of the element.

const box = await elementHandle.boundingBox();
await page.mouse.click(box.x + box.width / 2, box.y + box.height / 2);
BoundingBox box = elementHandle.boundingBox();
page.mouse().click(box.x + box.width / 2, box.y + box.height / 2);
box = await element_handle.bounding_box()
await page.mouse.click(box["x"] + box["width"] / 2, box["y"] + box["height"] / 2)
box = element_handle.bounding_box()
page.mouse.click(box["x"] + box["width"] / 2, box["y"] + box["height"] / 2)
var box = await elementHandle.BoundingBoxAsync();
await page.Mouse.ClickAsync(box.X + box.Width / 2, box.Y + box.Height / 2);

async method: ElementHandle.check

This method checks the element by performing the following steps:

  1. Ensure that element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
  2. Wait for actionability checks on the element, unless [option: force] option is set.
  3. Scroll the element into view if needed.
  4. Use [property: Page.mouse] to click in the center of the element.
  5. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.
  6. Ensure that the element is now checked. If not, this method throws.

If the element is detached from the DOM at any moment during the action, 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.

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

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

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

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

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

async method: ElementHandle.click

This method clicks the element by performing the following steps:

  1. Wait for actionability checks on the element, unless [option: force] option is set.
  2. Scroll the element into view if needed.
  3. Use [property: Page.mouse] to click in the center of the element, or the specified [option: position].
  4. Wait for initiated navigations to either succeed or fail, unless [option: noWaitAfter] option is set.

If the element is detached from the DOM at any moment during the action, 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.

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

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

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

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

async method: ElementHandle.contentFrame

  • returns: <[null]|[Frame]>

Returns the content frame for element handles referencing iframe nodes, or null otherwise

async method: ElementHandle.dblclick

  • langs:
    • alias-csharp: DblClickAsync

This method double clicks the element by performing the following steps:

  1. Wait for actionability checks on the element, unless [option: force] option is set.
  2. Scroll the element into view if needed.
  3. Use [property: Page.mouse] to double click in the center of the element, or the specified [option: position].
  4. 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.

If the element is detached from the DOM at any moment during the action, 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.

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

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

option: ElementHandle.dblclick.delay = %%-input-down-up-delay-%%

option: ElementHandle.dblclick.position = %%-input-position-%%

option: ElementHandle.dblclick.modifiers = %%-input-modifiers-%%

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

option: ElementHandle.dblclick.noWaitAfter = %%-input-no-wait-after-%%

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

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

async method: ElementHandle.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 elementHandle.dispatchEvent('click');
elementHandle.dispatchEvent("click");
await element_handle.dispatch_event("click")
element_handle.dispatch_event("click")
await elementHandle.DispatchEventAsync("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 elementHandle.dispatchEvent('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);
elementHandle.dispatchEvent("dragstart", arg);
# note you can only create data_transfer in chromium and firefox
data_transfer = await page.evaluate_handle("new DataTransfer()")
await element_handle.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()")
element_handle.dispatch_event("#source", "dragstart", {"dataTransfer": data_transfer})
var dataTransfer = await page.EvaluateHandleAsync("() => new DataTransfer()");
await elementHandle.DispatchEventAsync("dragstart", new Dictionary<string, object>
{
    { "dataTransfer", dataTransfer }
});

param: ElementHandle.dispatchEvent.type

  • type <[string]>

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

param: ElementHandle.dispatchEvent.eventInit

  • eventInit <[EvaluationArgument]>

Optional event-specific initialization properties.

async method: ElementHandle.evalOnSelector

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

Returns the return value of [param: expression].

The method finds an element matching the specified selector in the ElementHandles subtree and passes it as a first argument to [param: expression]. See Working with selectors for more details. If no elements match the selector, the method throws an error.

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

Examples:

const tweetHandle = await page.$('.tweet');
expect(await tweetHandle.$eval('.like', node => node.innerText)).toBe('100');
expect(await tweetHandle.$eval('.retweets', node => node.innerText)).toBe('10');
ElementHandle tweetHandle = page.querySelector(".tweet");
assertEquals("100", tweetHandle.evalOnSelector(".like", "node => node.innerText"));
assertEquals("10", tweetHandle.evalOnSelector(".retweets", "node => node.innerText"));
tweet_handle = await page.query_selector(".tweet")
assert await tweet_handle.eval_on_selector(".like", "node => node.innerText") == "100"
assert await tweet_handle.eval_on_selector(".retweets", "node => node.innerText") = "10"
tweet_handle = page.query_selector(".tweet")
assert tweet_handle.eval_on_selector(".like", "node => node.innerText") == "100"
assert tweet_handle.eval_on_selector(".retweets", "node => node.innerText") = "10"
var tweetHandle = await page.QuerySelectorAsync(".tweet");
Assert.AreEqual("100", await tweetHandle.EvalOnSelectorAsync(".like", "node => node.innerText"));
Assert.AreEqual("10", await tweetHandle.EvalOnSelectorAsync(".retweets", "node => node.innerText"));

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

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

param: ElementHandle.evalOnSelector.arg

  • arg <[EvaluationArgument]>

Optional argument to pass to [param: expression].

async method: ElementHandle.evalOnSelectorAll

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

Returns the return value of [param: expression].

The method finds all elements matching the specified selector in the ElementHandle's subtree and passes an array of matched elements as a first argument to [param: expression]. See Working with selectors for more details.

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

Examples:

<div class="feed">
  <div class="tweet">Hello!</div>
  <div class="tweet">Hi!</div>
</div>
const feedHandle = await page.$('.feed');
expect(await feedHandle.$$eval('.tweet', nodes => nodes.map(n => n.innerText))).toEqual(['Hello!', 'Hi!']);
ElementHandle feedHandle = page.querySelector(".feed");
assertEquals(Arrays.asList("Hello!", "Hi!"), feedHandle.evalOnSelectorAll(".tweet", "nodes => nodes.map(n => n.innerText)"));
feed_handle = await page.query_selector(".feed")
assert await feed_handle.eval_on_selector_all(".tweet", "nodes => nodes.map(n => n.innerText)") == ["hello!", "hi!"]
feed_handle = page.query_selector(".feed")
assert feed_handle.eval_on_selector_all(".tweet", "nodes => nodes.map(n => n.innerText)") == ["hello!", "hi!"]
var feedHandle = await page.QuerySelectorAsync(".feed");
Assert.AreEqual(new [] { "Hello!", "Hi!" }, await feedHandle.EvalOnSelectorAllAsync<string[]>(".tweet", "nodes => nodes.map(n => n.innerText)"));

param: ElementHandle.evalOnSelectorAll.arg

  • arg <[EvaluationArgument]>

Optional argument to pass to [param: expression].

async method: ElementHandle.fill

This method waits for actionability checks, focuses the element, fills it and triggers an input event after filling. Note that you can pass an empty string to clear the input field.

If the target element is not an <input>, <textarea> or [contenteditable] element, this method throws an error. However, if the element is inside the <label> element that has an associated control, the control will be filled instead.

To send fine-grained keyboard events, use [method: ElementHandle.type].

param: ElementHandle.fill.value

  • value <[string]>

Value to set for the <input>, <textarea> or [contenteditable] element.

option: ElementHandle.fill.force = %%-input-force-%%

async method: ElementHandle.hover

This method hovers over the element by performing the following steps:

  1. Wait for actionability checks on the element, unless [option: force] option is set.
  2. Scroll the element into view if needed.
  3. Use [property: Page.mouse] to hover over the center of the element, or the specified [option: position].
  4. Wait for initiated navigations to either succeed or fail, unless noWaitAfter option is set.

If the element is detached from the DOM at any moment during the action, 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.

option: ElementHandle.hover.position = %%-input-position-%%

option: ElementHandle.hover.modifiers = %%-input-modifiers-%%

option: ElementHandle.hover.force = %%-input-force-%%

async method: ElementHandle.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:

F1 - F12, Digit0- Digit9, KeyA- KeyZ, Backquote, Minus, Equal, Backslash, Backspace, Tab, Delete, Escape, ArrowDown, End, Enter, Home, Insert, PageDown, PageUp, ArrowRight, ArrowUp, etc.

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.

Depending on the [param: state] parameter, this method waits for one of the actionability checks to pass. This method throws when the element is detached while waiting, unless waiting for the "hidden" state.

  • "visible" Wait until the element is visible.
  • "hidden" Wait until the element is not visible or not attached. Note that waiting for hidden does not throw when the element detaches.
  • "stable" Wait until the element is both visible and stable.
  • "enabled" Wait until the element is enabled.
  • "disabled" Wait until the element is not enabled.
  • "editable" Wait until the element is editable.

If the element does not satisfy the condition for the [option: timeout] milliseconds, this method will throw.

param: ElementHandle.waitForElementState.state

  • state <[ElementState]<"visible"|"hidden"|"stable"|"enabled"|"disabled"|"editable">>

A state to wait for, see below for more details.

option: ElementHandle.waitForElementState.timeout = %%-input-timeout-%%

async method: ElementHandle.waitForSelector

  • returns: <[null]|[ElementHandle]>

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

Wait for the [param: selector] relative to the element handle 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.

await page.setContent(`<div><span></span></div>`);
const div = await page.$('div');
// Waiting for the 'span' selector relative to the div.
const span = await div.waitForSelector('span', { state: 'attached' });
page.setContent("<div><span></span></div>");
ElementHandle div = page.querySelector("div");
// Waiting for the "span" selector relative to the div.
ElementHandle span = div.waitForSelector("span", new ElementHandle.WaitForSelectorOptions()
  .setState(WaitForSelectorState.ATTACHED));
await page.set_content("<div><span></span></div>")
div = await page.query_selector("div")
# waiting for the "span" selector relative to the div.
span = await div.wait_for_selector("span", state="attached")
page.set_content("<div><span></span></div>")
div = page.query_selector("div")
# waiting for the "span" selector relative to the div.
span = div.wait_for_selector("span", state="attached")
await page.SetContentAsync("<div><span></span></div>");
var div = await page.QuerySelectorAsync("div");
// Waiting for the "span" selector relative to the div.
var span = await page.WaitForSelectorAsync("span", WaitForSelectorState.Attached);
