## ElementHandle.$eval() method
2020-06-22 15:21:57 +00:00
This method runs `document.querySelector` within the element and passes it as the first argument to `pageFunction` <!-- --> . If there's no element matching `selector` <!-- --> , the method throws an error.
If `pageFunction` returns a Promise, then `frame.$eval` would wait for the promise to resolve and return its value.
