Answer 1

These lines aren’t needed:
(function()
{
and this line:
})();

To disable a checkbox, checkbox.disabled = true; (where checkbox is the element you want to disable)

In your likeMe function, add an else statement that disables the checkbox if they aren’t similar.

I think that should work. here is how your code should be like:

<script type='text/javascript'>
(function()
{
 var allInps = document.getElementsByTagName('input'), allCb = [];

 for( var i in allInps )
  if( allInps[ i ].type === 'checkbox' )
  {
   allCb.push( allInps[ i ] );   
   allInps[ i ].onclick = likeMe;
  }

 function likeMe()
 {
  for(var i in allCb )
   if( allCb[ i ] !== this && allCb[ i ].id === this.id )
    allCb[ i ].checked = this.checked;
    else if (allCb[ i ].checked !== this.checked && allCb[ i ].id !== this.id )
    { 
     allCb[ i ].setAttribute('disabled',true);
   } 
   else { 
     allCb[ i ].removeAttribute('disabled');
   }
 }

})();

I think it will solve it.
