<div title="a1"></div>

You need = in your attribute-equals selector:

$('[title=a1]').click(function() {
   $(this).addClass('current');
}); 

Note, you should use something like div[title=a1] instead here...anything to narrow that expensive selector down.

To remove the current class from the previously selected one, just do this:

$('[title=a1]').click(function() {
   $('.current[title=a1]').removeClass('current');
   $(this).addClass('current');
});

You probably need to remove the class from ALL elements first.

  $('div[title=a1]').click(function() {
       $('div[title=a1]').removeClass('current'); //remove current fom all divs
       $(this).addClass('current'); //ad it to current div only
   });
