title: Is there a way to simulate a click on an alert in JavaScript?
body: <p>I have a page with an iframe whose source page is in a separate domain. From time to time, the source page generates an alert. When it does so, it stops what it is doing until the user clicks OK to the alert.</p>
  
  <p>What I would like to do is programmatically click OK on this alert so the source page can get back to being useful. Is this possible?</p>
