Answer 1

On event handler functions, the context (the this keyword) within the function, represents the HTML Element that triggered the event.

You can:

$('#check1,#check2').click(function() {
  var id = $(this).attr('id'); // or simply this.id
});

Answer 2

Inside your function you can get the ID of the element and compare..

if($(this).attr("id") == "check1") ...
