title: Limit Ajax mouseover
body: <p>I would like to know what's the best way to <strong>limit ajax call / time</strong>.</p>
  
  <p>I'm running the following js function when the user <code>mouseover</code> a table row.</p>
  
  <pre><code>function load()
  {
      $.ajax({
            type: "GET",
            url: "process/ajax.php",
            data: "action=action,
            success: function(msg)
                     {
                          if(msg!='')
                          {
                              displayStuff;
                          }
  
                     }
      });
  }
  </code></pre>
  
  <p>Should I create a timestamp and compare it with the previous one?, How can I do that in a <strong>global</strong> context.</p>
