that has nothing to do with ajax ... it is simple javascript ... have a look at the following example:

Expand|Select|Wrap|Line Numbers
  1. <html>
  2.     <head>
  3.         <script type="text/javascript">
  4.         function toggle_node(id, cbn) {
  5.             var n = document.getElementById(id);
  6.             n.disabled = cbn.checked;
  7.         }
  8.         </script>
  9.     </head>
  10.     <body>
  11.     <input type="button" id="mb" value="my_button"/>
  12.     <input type="checkbox" onclick="toggle_node('mb', this);"/>
  13.     </body>
  14. </html>
for a radiobutton just change the type of the button to radio and see how it works :)

kind regards

Changed the thread title. Please use meaningful titles for any threads started (see the FAQ entry Use a Good Thread Title). In particular, avoid words such as "urgent". It doesn't make the question any more urgent for someone answering your question.
