Trigger in page JavaScript function?

Hi, one example:

await page.evaluate(() =>
    ((window as any).__ARGOS__ as ArgosGlobal).prepareForScreenshot(),
  );

It works, so if it does not for you it means the function is not present on window

@gregberge Without Typescript would that example be:

await page.evaluate(() => window.pageFunction())

If so that didn't function in previous attempts. The function is a simple function in the global scope. It is defined as:

const pageFunction = (arg) => { ... }

You have to attach it to window to be able to call it in Playwright, the scope you are talking is « lost ». Attach it to window and it should solve your problem.
