This method fetches an element with selector and focuses it. If there's no element matching selector, the method throws an error.
class Page {
focus(selector: string): Promise<void>;
}
Parameter
</th><th>Type
</th><th>Description
</th></tr></thead> <tbody><tr><td>selector
</td><td>string
</td><td>selector to query the page for. CSS selectors can be passed as-is and a Puppeteer-specific selector syntax allows querying 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.
</td></tr> </tbody></table>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.
Shortcut for page.mainFrame().focus(selector).
