How to override window.open?

Question

I was wodering, is it possible to override window.open? I want to a add delay to every window.open call

Let's say one piece of code opens window using onClick, the other one using window.open, so is it possible to add like setTimeout to global window.open ?

Answer 1

First save a reference to window.open , then overwrite it with your own function that calls the saved reference after the timeout:

const origOpen = window.open;
window.open = (url) => {
  setTimeout(() => {
    origOpen(url);
  }, 1000);
};


window.open('https://www.google.com');
