title: jQuery to disable button not work
body: <p>I used to bind event to my button like :</p>
  
  <pre><code>$("input[name=add]").live("click",function(){...});
  </code></pre>
  
  <p>But I got another function to make them "enable" and "disabled" like :</p>
  
  <pre><code>RefreshBox() {
  
      $("input[name=add]").each(function(){
          if(...)
              $(this).attr("disabled","disabled");
          else
              $(this).attr("disabled","");
      })
  
  }
  </code></pre>
  
  <p>But in fact that it doesn't work as I expected. Buttons are still can be click and the event still works smoothly.</p>
  
  <p>PS:
  jQuery 1.4.1
  Browser: IE8 , after button disabled still can work.
  Browser: Chrome, disabled button success.</p>
