At every point of time, page exposes its current frame tree via the page.main_frame and frame.child_frames methods.
Frame object's lifecycle is controlled by three events, dispatched on the page object:
An example of dumping frame tree:
content <str> Raw JavaScript content to be injected into frame.path <Union[str, pathlib.Path]> Path to the JavaScript file to be injected into frame. If path is a relative path, then it is resolved relative to the current working directory.type <str> Script type. Use 'module' in order to load a Javascript ES6 module. See script for more details.url <str> URL of a script to be added.Returns the added tag when the script's onload fires or when the script content was injected into frame.
Adds a <script> tag into the page with the desired url or content.
content <str> Raw CSS content to be injected into frame.path <Union[str, pathlib.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.url <str> URL of the <link> tag.Returns the added tag when the stylesheet's onload fires or when the CSS content was injected into frame.
Adds a <link rel="stylesheet"> tag into the page with the desired url or a <style type="text/css"> tag with the content.
selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.force <bool> Whether to bypass the actionability checks. Defaults to false.no_wait_after <bool> Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to inaccessible pages. Defaults to false.timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.This method checks an element matching selector by performing the following steps:
selector. If there is none, wait until a matching element is attached to the DOM.force option is set. If the element is detached during the checks, the whole action is retried.no_wait_after option is set.When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.
selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.button <"left"|"right"|"middle"> Defaults to left.click_count <int> defaults to 1. See UIEvent.detail.delay <float> Time to wait between mousedown and mouseup in milliseconds. Defaults to 0.force <bool> Whether to bypass the actionability checks. Defaults to false.modifiers <List["Alt"|"Control"|"Meta"|"Shift"]> Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores current modifiers back. If not specified, currently pressed modifiers are used.no_wait_after <bool> Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to inaccessible pages. Defaults to false.position <Dict> A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the element.
timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.This method clicks an element matching selector by performing the following steps:
selector. If there is none, wait until a matching element is attached to the DOM.force option is set. If the element is detached during the checks, the whole action is retried.position.no_wait_after option is set.When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.
Gets the full HTML contents of the frame, including the doctype.
frame.dblclick(selector, **kwargs)#selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.button <"left"|"right"|"middle"> Defaults to left.delay <float> Time to wait between mousedown and mouseup in milliseconds. Defaults to 0.force <bool> Whether to bypass the actionability checks. Defaults to false.modifiers <List["Alt"|"Control"|"Meta"|"Shift"]> Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores current modifiers back. If not specified, currently pressed modifiers are used.no_wait_after <bool> Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to inaccessible pages. Defaults to false.position <Dict> A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the element.
timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.This method double clicks an element matching selector by performing the following steps:
selector. If there is none, wait until a matching element is attached to the DOM.force option is set. If the element is detached during the checks, the whole action is retried.position.no_wait_after option is set. Note that if the first click of the dblclick() triggers a navigation event, this method will reject.When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.
frame.dblclick() dispatches two click events and a single dblclick event.
selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.type <str> DOM event type: "click", "dragstart", etc.event_init <[EvaluationArgument]> Optional event-specific initialization properties.timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.The snippet below dispatches the click event on the element. Regardless of the visibility state of the elment, click is dispatched. This is equivalend to calling element.click().
Under the hood, it creates an instance of an event based on the given type, initializes it with event_init properties and dispatches it on the element. Events are composed, cancelable and bubble by default.
Since event_init 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:
selector <str> A selector to query for. See working with selectors for more details.arg <[EvaluationArgument]> Optional argument to pass to page_functionexpression <str> JavaScript expression to be evaluated in the browser context. If it looks like a function declaration, it is interpreted as a function. Otherwise, evaluated as an expression.force_expr <bool> Whether to treat given expression as JavaScript evaluate expression, even though it looks like an arrow function. Optional.Returns the return value of page_function
The method finds an element matching the specified selector within the frame and passes it as a first argument to page_function. See Working with selectors for more details. If no elements match the selector, the method throws an error.
If page_function returns a Promise, then frame.$eval would wait for the promise to resolve and return its value.
Examples:
frame.eval_on_selector_all(selector, expression, **kwargs)#selector <str> A selector to query for. See working with selectors for more details.arg <[EvaluationArgument]> Optional argument to pass to page_functionexpression <str> JavaScript expression to be evaluated in the browser context. If it looks like a function declaration, it is interpreted as a function. Otherwise, evaluated as an expression.force_expr <bool> Whether to treat given expression as JavaScript evaluate expression, even though it looks like an arrow function. Optional.Returns the return value of page_function
The method finds all elements matching the specified selector within the frame and passes an array of matched elements as a first argument to page_function. See Working with selectors for more details.
If page_function returns a Promise, then frame.$$eval would wait for the promise to resolve and return its value.
Examples:
frame.evaluate(expression, **kwargs)#arg <[EvaluationArgument]> Optional argument to pass to page_functionexpression <str> JavaScript expression to be evaluated in the browser context. If it looks like a function declaration, it is interpreted as a function. Otherwise, evaluated as an expression.force_expr <bool> Whether to treat given expression as JavaScript evaluate expression, even though it looks like an arrow function. Optional.Returns the return value of page_function
If the function passed to the frame.evaluate(expression, **kwargs) returns a Promise, then frame.evaluate(expression, **kwargs) would wait for the promise to resolve and return its value.
If the function passed to the frame.evaluate(expression, **kwargs) returns a non-Serializable value, then frame.evaluate(expression, **kwargs) returns undefined. DevTools Protocol also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity, and bigint literals.
A string can also be passed in instead of a function.
ElementHandle instances can be passed as an argument to the frame.evaluate(expression, **kwargs):
frame.evaluate_handle(expression, **kwargs)#arg <[EvaluationArgument]> Optional argument to pass to page_functionexpression <str> JavaScript expression to be evaluated in the browser context. If it looks like a function declaration, it is interpreted as a function. Otherwise, evaluated as an expression.force_expr <bool> Whether to treat given expression as JavaScript evaluate expression, even though it looks like an arrow function. Optional.Returns the return value of page_function as in-page object (JSHandle).
The only difference between frame.evaluate(expression, **kwargs) and frame.evaluate_handle(expression, **kwargs) is that [method: Frame.evaluateHandle`] returns in-page object (JSHandle).
If the function, passed to the frame.evaluate_handle(expression, **kwargs), returns a Promise, then frame.evaluate_handle(expression, **kwargs) would wait for the promise to resolve and return its value.
A string can also be passed in instead of a function.
JSHandle instances can be passed as an argument to the frame.evaluate_handle(expression, **kwargs):
frame.expect_navigation(**kwargs)#timeout <float> Maximum operation time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_navigation_timeout(timeout), browser_context.set_default_timeout(timeout), page.set_default_navigation_timeout(timeout) or page.set_default_timeout(timeout) methods.url <str|Pattern|Callable[URL]:bool> URL string, URL regex pattern or predicate receiving URL to match while waiting for the navigation.wait_until <"load"|"domcontentloaded"|"networkidle"> When to consider operation succeeded, defaults to load. Events can be either:
'domcontentloaded' - consider operation to be finished when the DOMContentLoaded event is fired.'load' - consider operation to be finished when the load event is fired.'networkidle' - consider operation to be finished when there are no network connections for at least 500 ms.Waits for the 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 method waits for the frame to navigate to a new URL. It is useful for when you run code which will indirectly cause the frame to navigate. Consider this example:
noteUsage of the History API to change the URL is considered a navigation.
frame.fill(selector, value, **kwargs)#selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.value <str> Value to fill for the <input>, <textarea> or [contenteditable] element.no_wait_after <bool> Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to inaccessible pages. Defaults to false.timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.This method waits for an element matching selector, waits for actionability checks, focuses the element, fills it and triggers an input event after filling. If the element matching selector is not an <input>, <textarea> or [contenteditable] element, this method throws an error. Note that you can pass an empty string to clear the input field.
To send fine-grained keyboard events, use frame.type(selector, text, **kwargs).
frame.focus(selector, **kwargs)#selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used.

If there's no element matching selector, the method waits until a matching element appears in the DOM.
Returns the frame or iframe element handle which corresponds to this frame.
This is an inverse of element_handle.content_frame(). Note that returned handle actually belongs to the parent frame.
This method throws an error if the frame has been detached before frameElement() returns.
selector <str> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.name <str> Attribute name to get the value for.timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.Returns element attribute value.
frame.goto(url, **kwargs)#url <str> URL to navigate frame to. The url should include scheme, e.g. https://.referer <str> Referer header value. If provided it will take preference over the referer header value set by page.set_extra_http_headers(headers).timeout <float> Maximum operation time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_navigation_timeout(timeout), browser_context.set_default_timeout(timeout), page.set_default_navigation_timeout(timeout) or page.set_default_timeout(timeout) methods.wait_until <"load"|"domcontentloaded"|"networkidle"> When to consider operation succeeded, defaults to load. Events can be either:
'domcontentloaded' - consider operation to be finished when the DOMContentLoaded event is fired.'load' - consider operation to be finished when the load event is fired.'networkidle' - consider operation to be finished when there are no network connections for at least 500 ms.Returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect.
frame.goto will throw an error if:
timeout is exceeded during navigation.frame.goto will not throw an error when any valid HTTP status code is returned by the remote server, including 404 "Not Found" and 500 "Internal Server Error". The status code for such responses can be retrieved by calling response.status.
frame.goto either throws an error or returns a main resource response. The only exceptions are navigation to about:blank or navigation to the same URL with a different hash, which would succeed and return null.
Headless mode doesn't support navigation to a PDF document. See the upstream issue.

The default value can be changed by using the browser_context.set_default_navigation_timeout(timeout), browser_context.set_default_timeout(timeout), page.set_default_navigation_timeout(timeout) or page.set_default_timeout(timeout) methods.Waits for the required load state to be reached.
This returns when the frame reaches a required load state, load by default. The navigation must have been committed when this method is called. If current document has already reached the required state, resolves immediately.
selector <str> A selector to query for. See working with selectors for more details.state <"attached"|"detached"|"visible"|"hidden"> Defaults to 'visible'. Can be either:
'attached' - wait for element to be present in DOM.'detached' - wait for element to not be present in DOM.'visible' - wait for element to have non-empty bounding box and no visibility:hidden. Note that element without any content or with display:none has an empty bounding box and is not considered visible.'hidden' - wait for element to be either detached from DOM, or have an empty bounding box or visibility:hidden. This is opposite to the 'visible' option.timeout <float> Maximum time in milliseconds, defaults to 30 seconds, pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout(timeout) or page.set_default_timeout(timeout) methods.Returns when element specified by selector satisfies state option. Returns null if waiting for hidden or detached.
Wait for the selector to satisfy state option (either appear/disappear from dom, or become visible/hidden). If at the moment of calling the method selector already satisfies the condition, the method will return immediately. If the selector doesn't satisfy the condition for the timeout milliseconds, the function will throw.
This method works across navigations:
frame.wait_for_timeout(timeout)#timeout <float> A timeout to wait forWaits for the given timeout in milliseconds.
Note that frame.waitForTimeout() should only be used for debugging. Tests using the timer in production are going to be flaky. Use signals such as network events, selectors becoming visible and others instead.
