Dialogs
Playwright can interact with the web page dialogs such as alert
, confirm
, prompt
as well as beforeunload
confirmation.

alert(), confirm(), prompt() dialogsBy default, dialogs are auto-dismissed by Playwright, so you don't have to handle them. However, you can register a dialog handler before the action that triggers the dialog to accept or decline it.

- Async
note
page.on("dialog") listener must handle the dialog. Otherwise your action will stall, be it page.click(selector, **kwargs), page.evaluate(expression, **kwargs) or any other. That's because dialogs in Web are modal and block further page execution until they are handled.
As a result, following snippet will never resolve:

note
If there is no listener for page.on("dialog"), all dialogs are automatically dismissed.

beforeunload dialogWhen page.close(**kwargs) is invoked with the truthy run_before_unload
value, it page runs its unload handlers. This is the only case when page.close(**kwargs) does not wait for the page to actually close, because it might be that the page stays open in the end of the operation.
You can register a dialog handler to handle the beforeunload dialog yourself:
