title: How to get the jQuery `$(this)` id?
body: <p>How can I get the <code>id</code> of the element that triggered the jQuery <code>.change()</code> function?
  The function itself works properly, but I need a specific action for a selector with <code>id="next"</code>.</p>
  
  <pre><code>$("select").change(function() {
      [...snip....]
      alert( $(this).attr('id') );  // &lt;---- not working
  }
  </code></pre>
  
  <p>Any ideas why the alert above isn't working?</p>
