Answer 1

use this: 


<script> 
    function enable_txtbox(id, id1) { 
     var a =(document.getElementsByName("name1")); 
     for(var i=0;i<a.length;i++){ 
      var b=a[i].id; 
      if(document.getElementById(b).disabled == true) 
      { 
       document.getElementById(b).disabled = false; 
      } 
      else 
      { 
       document.getElementById(b).disabled = true; 
      } 
     } 
      return true; 
     } 
    </script>
