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](https://pptr.dev/guides/page-interactions#selectors) to query the page for. [CSS selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors) can be passed as-is and a [Puppeteer-specific selector syntax](https://pptr.dev/guides/page-interactions#non-css-selectors) allows querying by [text](https://pptr.dev/guides/page-interactions#text-selectors--p-text), [a11y role and name](https://pptr.dev/guides/page-interactions#aria-selectors--p-aria), and [xpath](https://pptr.dev/guides/page-interactions#xpath-selectors--p-xpath) and [combining these queries across shadow roots](https://pptr.dev/guides/page-interactions#querying-elements-in-shadow-dom). Alternatively, you can specify the selector type using a [prefix](https://pptr.dev/guides/page-interactions#prefixed-selector-syntax). 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).
