title: Detect if the value of a text input changes with no event
body: <p>I'm looking to get the value of this input if it changes. I have a map.swf that makes the value change depending on what the user selects in the .swf, so I was wondering how to get this done.</p>
  
  <pre><code>&lt;a href="map.php" onclick='return GB_showCenter("",this.href,380,780);' class="page"&gt;See Map&lt;/a&gt;
  &lt;input name="sector_e" type="text" id="sector_e" value="Please click The Map" size="1" readonly&gt;
  </code></pre>
  
  <p>This jQuery only alerts me if I press a key, I want it to alert if the value changes without any event.   </p>
  
  <pre><code>$('#sector_e').bind("keyup", function() {    
      alert($(this).val());
  });
  </code></pre>
