  </tr>
</table>

<a id="btnExcellent" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnExcellent&#39;,&#39;&#39;)">Excellent</a>
<a id="btnFine" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnFine&#39;,&#39;&#39;)">Fine</a>
<a id="btnBad" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnBad&#39;,&#39;&#39;)">Bad</a>
<a id="btnSkip" class="btn btn-primary" href="javascript:__doPostBack(&#39;btnSkip&#39;,&#39;&#39;)">Skip</a>

REQUIREMENT:

I want to disable the btnFour button when I click the first radio button (i.e. with value one). If I click the remaining two radiobuttons, I want first three Buttons to be disabled except the last one.

It doesn't work the way I want. If I take simple HTML buttons then it works, but it doesn't work in the case of LinkButtons. Any help would be much appreciated.

Thank you.

You can try below code, just pass the value of radio button while calling disable function and make enable or disable of relevant buttons

Code Snippet

function disableButtons(val) {
   if (val == 'clear') {
     $('#btnExcellent, #btnFine, #btnBad').addClass('disabled');
     $('#btnSkip').removeClass('disabled');
   } else {
     $('#btnExcellent, #btnFine, #btnBad').removeClass('disabled');
     $('#btnSkip').addClass('disabled');
   }
   
   $('a.disabled').each(function(){
      var href = $(this).attr('href');
      //console.log('attr = ' + href);
      $(this).data('href', href);
      $(this).attr('href', '#')
   });
   $('a:not(.disabled)').each(function(){
      var href = $(this).data('href');
      //console.log('data = ' + href);
      if(href) {
         $(this).attr('href', href);
      }
   });
}
a.disabled {
  opacity: 0.1;
}
