When trying to click on a button with a specific label, I use the following code:
const button = await this.page.$$eval('button', (elms: Element[], label: string) => {
const el: Element = elms.find((el: Element) => el.textContent === label)
console.log(el);
return el;
}, label);
await button.click(); // button is undefined
Despite seeing the element in the browser console when using console.log() and being able to .click() on it, the returned value does not make it into the 'button' variable.
This discrepancy raises the question:
According to the documentation for $$eval:
returns: > Promise which resolves to the return value of pageFunction
