Page.waitForFileChooser() method

This method is typically coupled with an action that triggers file choosing. The following example clicks a button that issues a file chooser and then responds with /tmp/myfile.pdf as if a user has selected this file.

const [fileChooser] = await Promise.all([
page.waitForFileChooser(),
page.click('#upload-file-button'),
// some button that triggers file selection
]);
await fileChooser.accept(['/tmp/myfile.pdf']);

NOTE: This must be called before the file chooser is launched. It will not return a currently active file chooser.

Signature:

waitForFileChooser(options?: WaitTimeoutOptions): Promise<FileChooser>;

Parameters

Parameter	Type	Description
options	WaitTimeoutOptions	Optional waiting parameters

Returns:

Promise<FileChooser>

Resolves after a page requests a file picker.

Remarks

NOTE: In non-headless Chromium, this method results in the native file picker dialog not showing up for the user.
