title: jquery override event
body: <p>I have an anchor like this</p>
  
  <pre><code>&lt;a href='#' onclick='return showform(this)'&gt;click me&lt;/a&gt;
  </code></pre>
  
  <p>But I want to be able to override the onclick function, how to do this in jquery?</p>
  
  <p>because it seems when I add</p>
  
  <pre><code>$('a').click( function() { alert('hi there!'); } );
  </code></pre>
  
  <p>the new click handler is not overriding the old one</p>
