How do I dynamically enable/disable links with jQuery?

Solution 1:

$('selector_for_links_to_disable').bind('click', function(e){
        e.preventDefault();
})

and for enabling:

$('selector_for_links_to_enable').unbind('click')

You could do something like:

$('.links').click(function(e){
  if( [some conditions] ){
    e.preventDefault();
  }
});

Be sure to show that they no longer work somehow, otherwise your users will get confused, lol.
