How to apply jquery command to multiple divs?

Question

Let's say I want to hide multiple divs at once.

$("#something").click(function() {
  $("#one").hide();
  $("#two").hide();
  $("#three").hide();
});

How can I reduce the middle three lines to one line?

Answer 1

$('#one, #two, #three').hide();

or give them a class and hide everything at once

$('.class').hide();

Answer 2

Just add such a comma

$("#one, #two, #three").hide();

Answer 3

Just comma separate them :)

$("#something").click(function() {
  $("#one, #two, #three").hide();
});
