你如何通过id选择多个元素？

Question

I have two identical click events for two different elements that do not share a class, as such:

$("#element_1").click(function(){
  alert("hello world");
});

$("#element_2").click(function(){
  alert("hello world");
});

I am looking for a way to assign that same click function to both of them without externalizing the function or repeating it (as seen above). If the elements shared the same class, I would have done something like this:

$(".element_class").click(function(){
  alert("hello world");
});

but they do not. How do I achieve something like that in jQuery 1.3?

Thank you!

Answer 1

$('#element_1, #element_2').bind('click', function() {...});

Answer 2

You can use

$('#element1, #element2').click();

Or

$('#element1').add('#element2').click();

Both methods are good
