mouse click somewhere else on page (not on a specific div)

Question

I want to close a little pop-up box in page when user has clicked anywhere on the page other than box area. how to find it?

Answer 1

@jAndy's solution is good, but I wanted to mention Ben Alman's "Outside Events" plugin as well. Here's a quick example using it:

$("#popup").bind("clickoutside", function(event){
  $(this).hide();
});
