Java playwright usage of page.waitForFunction()

Question

I am trying to figure out how to use the page.waitForFunction() in Playwright in Java.

I would like for a page.evaluate() to run first, and for the page.waitForFunction() to wait on it, before continuing.

I have the following: page.waitForFunction(() => page.evaluate("document.readyState").equals("complete"));

But syntactically that is incorrect or maybe I'm doing something wrong.

Answer 1

You have to pass a string to the waitForFunction

page.waitForFunction("() => page.evaluate('document.readyState').equals('complete')");
