--- id: navigations title: "Navigations" --- Playwright can navigate to URLs and handle navigations caused by page interactions. This guide covers common scenarios to wait for page navigations and loading to complete. - [Navigation lifecycle](#navigation-lifecycle) - [Scenarios initiated by browser UI](#scenarios-initiated-by-browser-ui) - [Scenarios initiated by page interaction](#scenarios-initiated-by-page-interaction) - [Advanced patterns](#advanced-patterns) ## Navigation lifecycle Playwright splits the process of showing a new document in a page into **navigation** and **loading**. **Navigations** can be initiated by changing the page URL or by interacting with the page (e.g., clicking a link). Navigation ends when response headers have been parsed and session history is updated. The navigation intent may be canceled, for example, on hitting an unresolved DNS address or transformed into a file download. Only after the navigation succeeds, page starts **loading** the document. **Loading** covers getting the remaining response body over the network, parsing, executing the scripts and firing load events: - [page.url()](api/class-page.md#pageurl) is set to the new url - document content is loaded over network and parsed - [page.on('domcontentloaded')](api/class-page.md#pageondomcontentloaded) event is fired - page executes some scripts and loads resources like stylesheets and images - [page.on('load')](api/class-page.md#pageonload) event is fired - page executes dynamically loaded scripts - `networkidle` is fired when no new network requests are made for 500 ms ## Scenarios initiated by browser UI Navigations can be initiated by changing the URL bar, reloading the page or going back or forward in session history. ### Auto-wait Navigating to a URL auto-waits for the page to fire the `load` event. If the page does a client-side redirect before `load`, `page.goto` will auto-wait for the redirected page to fire the `load` event. ```js // Navigate the page await page.goto('https://example.com'); ``` ### Custom wait Override the default behavior to wait until a specific event, like `networkidle`. ```js // Navigate and wait until network is idle await page.goto('https://example.com', { waitUntil: 'networkidle' }); ``` ### Wait for element In lazy-loaded pages, it can be useful to wait until an element is visible with [page.waitForSelector(selector[, options])](api/class-page.md#pagewaitforselectorselector-options). Alternatively, page interactions like [page.click(selector[, options])](api/class-page.md#pageclickselector-options) auto-wait for elements. ```js // Navigate and wait for element await page.goto('https://example.com'); await page.waitForSelector('text=Example Domain'); // Navigate and click element // Click will auto-wait for the element await page.goto('https://example.com'); await page.click('text=Example Domain'); ``` #### API reference - [page.goto(url[, options])](api/class-page.md#pagegotourl-options) - [page.reload([options])](api/class-page.md#pagereloadoptions) - [page.goBack([options])](api/class-page.md#pagegobackoptions) - [page.goForward([options])](api/class-page.md#pagegoforwardoptions) ## Scenarios initiated by page interaction In the scenarios below, `page.click` initiates a navigation and then waits for the navigation to complete. ### Auto-wait By default, `page.click` will wait for the navigation step to complete. This can be combined with a page interaction on the navigated page which would auto-wait for an element. ```js // Click will auto-wait for navigation to complete await page.click('text=Login'); // Fill will auto-wait for element on navigated page await page.fill('#username', 'John Doe'); ``` ### Custom wait `page.click` can be combined with [page.waitForLoadState([state, options])](api/class-page.md#pagewaitforloadstatestate-options) to wait for a loading event. ```js await page.click('button'); // Click triggers navigation await page.waitForLoadState('networkidle'); // This resolves after 'networkidle' ``` ### Wait for element In lazy-loaded pages, it can be useful to wait until an element is visible with [page.waitForSelector(selector[, options])](api/class-page.md#pagewaitforselectorselector-options). Alternatively, page interactions like [page.click(selector[, options])](api/class-page.md#pageclickselector-options) auto-wait for elements. ```js // Click triggers navigation await page.click('text=Login'); // Click will auto-wait for the element await page.waitForSelector('#username', 'John Doe'); // Click triggers navigation await page.click('text=Login'); // Fill will auto-wait for element await page.fill('#username', 'John Doe'); ``` ### Asynchronous navigation Clicking an element could trigger asychronous processing before initiating the navigation. In these cases, it is recommended to explicitly call [page.waitForNavigation([options])](api/class-page.md#pagewaitfornavigationoptions). For example: * Navigation is triggered from a `setTimeout` * Page waits for network requests before navigation ```js await Promise.all([ page.click('a'), // Triggers a navigation after a timeout page.waitForNavigation(), // Waits for the next navigation ]); ``` The `Promise.all` pattern prevents a race condition between `page.click` and `page.waitForNavigation` when navigation happens quickly. ### Multiple navigations Clicking an element could trigger multiple navigations. In these cases, it is recommended to explicitly [page.waitForNavigation([options])](api/class-page.md#pagewaitfornavigationoptions) to a specific url. For example: * Client-side redirects issued after the `load` event * Multiple pushes to history state ```js await Promise.all([ page.waitForNavigation({ url: '**/login' }), page.click('a'), // Triggers a navigation with a script redirect ]); ``` The `Promise.all` pattern prevents a race condition between `page.click` and `page.waitForNavigation` when navigation happens quickly. ### Loading a popup When popup is opened, explicitly calling [page.waitForLoadState([state, options])](api/class-page.md#pagewaitforloadstatestate-options) ensures that popup is loaded to the desired state. ```js const [ popup ] = await Promise.all([ page.waitForEvent('popup'), page.click('a[target="_blank"]'), // Opens popup ]); await popup.waitForLoadState('load'); ``` #### API reference - [page.click(selector[, options])](api/class-page.md#pageclickselector-options) - [page.waitForLoadState([state, options])](api/class-page.md#pagewaitforloadstatestate-options) - [page.waitForSelector(selector[, options])](api/class-page.md#pagewaitforselectorselector-options) - [page.waitForNavigation([options])](api/class-page.md#pagewaitfornavigationoptions) - [page.waitForFunction(pageFunction[, arg, options])](api/class-page.md#pagewaitforfunctionpagefunction-arg-options) ## Advanced patterns For pages that have complicated loading patterns, [page.waitForFunction(pageFunction[, arg, options])](api/class-page.md#pagewaitforfunctionpagefunction-arg-options) is a powerful and extensible approach to define a custom wait criteria. ```js await page.goto('http://example.com'); await page.waitForFunction(() => window.amILoadedYet()); // Ready to take a screenshot, according to the page itself. await page.screenshot(); ``` #### API reference - [page.waitForFunction(pageFunction[, arg, options])](api/class-page.md#pagewaitforfunctionpagefunction-arg-options) [Playwright]: api/class-playwright.md "Playwright" [Browser]: api/class-browser.md "Browser" [BrowserContext]: api/class-browsercontext.md "BrowserContext" [Page]: api/class-page.md "Page" [Frame]: api/class-frame.md "Frame" [ElementHandle]: api/class-elementhandle.md "ElementHandle" [JSHandle]: api/class-jshandle.md "JSHandle" [ConsoleMessage]: api/class-consolemessage.md "ConsoleMessage" [Dialog]: api/class-dialog.md "Dialog" [Download]: api/class-download.md "Download" [Video]: api/class-video.md "Video" [FileChooser]: api/class-filechooser.md "FileChooser" [Keyboard]: api/class-keyboard.md "Keyboard" [Mouse]: api/class-mouse.md "Mouse" [Touchscreen]: api/class-touchscreen.md "Touchscreen" [Request]: api/class-request.md "Request" [Response]: api/class-response.md "Response" [Selectors]: api/class-selectors.md "Selectors" [Route]: api/class-route.md "Route" [WebSocket]: api/class-websocket.md "WebSocket" [TimeoutError]: api/class-timeouterror.md "TimeoutError" [Accessibility]: api/class-accessibility.md "Accessibility" [Worker]: api/class-worker.md "Worker" [BrowserServer]: api/class-browserserver.md "BrowserServer" [BrowserType]: api/class-browsertype.md "BrowserType" [Logger]: api/class-logger.md "Logger" [ChromiumBrowser]: api/class-chromiumbrowser.md "ChromiumBrowser" [ChromiumBrowserContext]: api/class-chromiumbrowsercontext.md "ChromiumBrowserContext" [ChromiumCoverage]: api/class-chromiumcoverage.md "ChromiumCoverage" [CDPSession]: api/class-cdpsession.md "CDPSession" [FirefoxBrowser]: api/class-firefoxbrowser.md "FirefoxBrowser" [WebKitBrowser]: api/class-webkitbrowser.md "WebKitBrowser" [Array]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array "Array" [Buffer]: https://nodejs.org/api/buffer.html#buffer_class_buffer "Buffer" [ChildProcess]: https://nodejs.org/api/child_process.html "ChildProcess" [Element]: https://developer.mozilla.org/en-US/docs/Web/API/element "Element" [Error]: https://nodejs.org/api/errors.html#errors_class_error "Error" [Evaluation Argument]: ./core-concepts.md#evaluationargument "Evaluation Argument" [Map]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map "Map" [Object]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object "Object" [Promise]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise "Promise" [RegExp]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp "RegExp" [Serializable]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#Description "Serializable" [UIEvent.detail]: https://developer.mozilla.org/en-US/docs/Web/API/UIEvent/detail "UIEvent.detail" [URL]: https://nodejs.org/api/url.html "URL" [USKeyboardLayout]: ../src/usKeyboardLayout.ts "USKeyboardLayout" [UnixTime]: https://en.wikipedia.org/wiki/Unix_time "Unix Time" [boolean]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#Boolean_type "Boolean" [function]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function "Function" [iterator]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols "Iterator" [null]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/null "null" [number]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#Number_type "Number" [origin]: https://developer.mozilla.org/en-US/docs/Glossary/Origin "Origin" [selector]: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors "selector" [Readable]: https://nodejs.org/api/stream.html#stream_class_stream_readable "Readable" [string]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#String_type "string" [xpath]: https://developer.mozilla.org/en-US/docs/Web/XPath "xpath"
