The problem with the tag <noindex>

The problem with the tag <noindex>

  1. <a id="code">LINK</a>
  2. <noindex id="noindex">
  3. <textarea rows="3" style="width:390px" readonly="readonly" >
  4. </noindex>

  1. $(document).ready(function()
  2. {
  3.     $("#code").click(function()
  4.      {
  5.         $('#noindex').hide();
  6.      })
  7.  })
For Internet Explorer browsers not working this example. Why?
