How to hide a div when the mouse is clicked outside the div

I've a HTML div and I want to hide it whenever the user clicks on the page anywhere outside the div. Which clicking on which element should I trig开发者_运维百科ger the onclick event??

---

$('#mydiv').click(function(e) { e.stopImmediatePropagation(); });
$(document.body).one("click", function() {
    $('#mydiv').hide();
});

Since mydiv is also a child of the body element, you don't want that when clicking on that element, the element would dissappear.
So when people click on the mydiv, you want it to stop bubbling up to the body element, that is why first you register a click event on your mydiv, and tell it to stop bubbling.

Assuming you're using the latest jQuery, v1.4.4:

$(<the div you want hidden>).click(false); //stop click event from bubbling up to the document
$(document).one('click', function(){
  $(<the div you want hidden>).hide(); //which will hide the div
});

In other words, this code says 'hide the div if you click on this page, unless you click on the div'.

Re: Toggle button

Then you'll have something like:

$('button').click(function(){
  $('div').toggle();
});
$('div').click(false);
$(document).click(function(){
  $('div').hide();
  //reset the toggle state, e.g.
  $('button').removeClass('selected');
});

The BODY element.
