$("#btnDel").attr("id", "btnDel" + $("#hid").attr("value")); 

Answer 1

For your example it would be like this:

$("#btnDel").click(function() {
  alert(this.id);
});

Note that you can’t loop the code you have, IDs have to be unique, you’ll get all sorts of side-effects if they’re not, as it’s invalid HTML. If you wanted a click handler for any input, change the selector, like this:

$("input").click(function() {
  alert(this.id);
});
