title: Keep calling on a function while mouseover
body: <p>how do I keep calling a function on mouseover while the mouse is hovered over an <em>html</em> element</p>
  
  <p><strong>Example:</strong></p>
  
  <pre><code>&lt;script&gt;
      function a() {
          "special code hear"
      }
  &lt;/script&gt;
  &lt;div onmouseover( 'a()')&gt;&amp;nbsp;&lt;/div&gt;
  </code></pre>
  
  <p>How can I keep calling the function a while the mouse is hovered over the div instead of having it call the function once.</p>
