title: Click location in iframe relative to whole page
body: <h1>Problem</h1>
  <p>I have a page with several iframes, and a single Javascript file that is loaded in every frame. I register a <code>.click()</code> function to record usage. I'm trying to find the x/y position of a click relative to the entire browser window. Screen x/y doesn't work if the browser moves, and page x/y or client x/y gives the position relative to the frame.</p>
  <h1>Question</h1>
  <p>I need to do more processing within the frame, so is there a way to get the x/y position of the click relative to the browser using only javascript in the frame?</p>
