# Page.waitForFileChooser() method
|
|
|
|
This method is typically coupled with an action that triggers file choosing.
|
|
|
|
:::caution
|
|
|
|
This must be called before the file chooser is launched. It will not return a currently active file chooser.
|
|
|
|
:::
|
|
|
|
:::caution
|
|
|
|
Interception of file dialogs triggered via DOM APIs such as window.showOpenFilePicker is currently not supported.

#### Signature:

|
|
abstract waitForFileChooser(
|
|
options?: WaitTimeoutOptions
|
|

|
|

|
</td><td>
|

|

</td></tr>
|
|
</tbody></table>
|
|
**Returns:**
|
|
|
|
Promise<[FileChooser](./puppeteer.filechooser.md)>
|
|
|
|
## Remarks
|
|
|
|
In the "headful" browser, this method results in the native file picker dialog `not showing up` for the user.
|
|
|
|
## Example
|
|
|
|
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.
|
|
|
|
```ts
|
|
const [fileChooser] = await Promise.all([
|
|
page.waitForFileChooser(),
|
|
page.click('#upload-file-button'),
|
|
// some button that triggers file selection
|
|
]);
|
|
await fileChooser.accept(['/tmp/myfile.pdf']);
|
|
```
