title: jQuery trigger('click') problem
body: <p>I have clickable row, that will fire link <code>onclick</code> event, but <code>trigger()</code> cause a new click event on <code>tr.clickable</code> and go into loop. How to prevent this ?</p>
  
  <pre><code>&lt;table&gt;
      &lt;tr class="clickable"&gt;
          &lt;td&gt;Test row&lt;/td&gt;
          &lt;td&gt;&lt;a href="#" onclick="alert('click');" class="trigger"&gt;&lt;/a&gt;&lt;/td&gt;        
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>js:</p>
  
  <pre><code>$('tr.clickable').click(function(){
      var trigger = $(this).find('a.trigger');
      trigger.trigger('click');
  });
  </code></pre>
