title: How to detect middle mouse button click?
body: <p>All of the questions I've seen on how to detect a middle mouse click in JavaScript are related to jQuery, but I'm wondering how I can detect middle mouse button clicks with regular JavaScript. I tried using <code>onClick()</code>, but it only appears to work for the left mouse button.</p>
  
  <p>Is there a JavaScript function that can detect both left and middle mouse button clicks or, if not, that can detect middle mouse button clicks?</p>
  
  <p>The reason I ask is that I want to make a function call when links are clicked, irregardless of whether the left or middle mouse button was used.</p>
