Signature: ```typescript $$eval(selector: string, pageFunction: (elements: Element[], ...args: unknown[]) => ReturnType | Promise, ...args: SerializableOrJSHandle[]): Promise>; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | selector | string | the [selector](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors) to query for | | pageFunction | (elements: Element\[\], ...args: unknown\[\]) => ReturnType \| Promise<ReturnType> | the function to be evaluated in the page context. Will be passed the result of Array.from(document.querySelectorAll(selector)) as its first argument. | | args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)\[\] | any additional arguments to pass through to pageFunction. | Returns: Promise<[WrapElementHandle](./puppeteer.wrapelementhandle.md)<ReturnType>> 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 `$$eval` will wait for the promise to resolve and then return its value. ## Example 1 ``` // get the amount of divs on the page const divCount = await page.$$eval('div', divs => divs.length); // get the text content of all the `.options` elements: const options = await page.$$eval('div > span.options', options => { return options.map(option => option.textContent) }); ``` If you are using TypeScript, you may have to provide an explicit type to the first argument of the `pageFunction`. By default it is typed as `Element[]`, but you may need to provide a more specific sub-type: ## Example 2 ``` // if you don't provide HTMLInputElement here, TS will error // as `value` is not on `Element` await page.$$eval('input', (elements: HTMLInputElement[]) => { 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 `$$eval`: ## Example 3 ``` // The compiler can infer the return type in this case, but if it can't // or if you want to be more explicit, provide it as the generic type. const allInputValues = await page.$$eval( 'input', (elements: HTMLInputElement[]) => elements.map(e => e.textContent) ); ```
