Page.focus() method

This method fetches an element with selector and focuses it. If there's no element matching selector, the method throws an error.

Signature

class Page {
  focus(selector: string): Promise<void>;
}

Parameters

Parameter	Type	Description
selector	string	selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows quering by text, a11y role and name, and xpath and combining these queries across shadow roots. Alternatively, you can specify the selector type using a prefix. If there are multiple elements satisfying the selector, the first will be focused.

Returns:

Promise<void>

Promise which resolves when the element matching selector is successfully focused. The promise will be rejected if there is no element matching selector.

Remarks

Shortcut for page.mainFrame().focus(selector).
