--- sidebar_label: Page.$$eval --- # Page.$$eval() method This method returns all elements matching the selector and passes the resulting array as the first argument to the `pageFunction`. #### Signature: ```typescript class Page { $$eval< Selector extends string, Params extends unknown[], Func extends EvaluateFuncWith< Array>, Params > = EvaluateFuncWith>, Params>, >( selector: Selector, pageFunction: Func | string, ...args: Params ): Promise>>; } ``` ## Parameters
Parameter Type Description
selector Selector [selector](https://pptr.dev/guides/page-interactions#query-selectors) to query page for. [CSS selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors) can be passed as-is and a [Puppeteer-specific seletor syntax](https://pptr.dev/guides/page-interactions#p-selectors) allows quering by [text](https://pptr.dev/guides/page-interactions#text-selectors--p-text), [a11y role and name](https://pptr.dev/guides/page-interactions#aria-selectors--p-aria), and [xpath](https://pptr.dev/guides/page-interactions#xpath-selectors--p-xpath) and [combining these queries across shadow roots](https://pptr.dev/guides/page-interactions#-and--combinators). Alternatively, you can specify a selector type using a prefix [prefix](https://pptr.dev/guides/page-interactions#built-in-selectors).
pageFunction Func \| string the function to be evaluated in the page context. Will be passed an array of matching elements as its first argument.
args Params any additional arguments to pass through to `pageFunction`.
**Returns:** Promise<Awaited<ReturnType<Func>>> The result of calling `pageFunction`. If it returns an element it is wrapped in an [ElementHandle](./puppeteer.elementhandle.md), else the raw value itself is returned. ## Remarks If `pageFunction` returns a promise `$$eval` will wait for the promise to resolve and then return its value. ## Example 1 ```ts // get the amount of divs on the page const divCount = await page.$$eval('div', divs => divs.length); // get the text content of all the `.options` elements: const options = await page.$$eval('div > span.options', options => { return options.map(option => option.textContent); }); ``` If you are using TypeScript, you may have to provide an explicit type to the first argument of the `pageFunction`. By default it is typed as `Element[]`, but you may need to provide a more specific sub-type: ## Example 2 ```ts await page.$$eval('input', elements => { return elements.map(e => e.value); }); ``` The compiler should be able to infer the return type from the `pageFunction` you provide. If it is unable to, you can use the generic type to tell the compiler what return type you expect from `$$eval`: ## Example 3 ```ts const allInputValues = await page.$$eval('input', elements => elements.map(e => e.textContent) ); ```
