title: Javascript: Capture mouse wheel event and do not scroll the page?
body: <p>I'm trying to prevent a mousewheel event captured by an element of the page to cause scrolling.</p>
  
  <p>I expected <code>false</code> as last parameter to have the expected result, but using the mouse wheel over this "canvas" element still causes scrolling:</p>
  
  <pre><code>this.canvas.addEventListener('mousewheel', function(event) {
     mouseController.wheel(event);
  }, false);
  </code></pre>
  
  <p>Outside of this "canvas" element, the scroll needs to happen. Inside, it must only trigger the <code>.wheel()</code> method.
  What am I doing wrong?</p>
