This plugin enables to close a jQuery UI dialog when clicking outside anywhere outside the dialog or the element that opened it. A simple demo is available as well.

A demo is available here : http://www.coheractio.com/blog/jquery-ui-dialog-close-when-clicking-outside-demo

In order to use it, simply add "jquery.ui.dialog-clickoutside.js" located in the "ui-clickoutside" folder to your page after any javascript required by the jQuery UI dialog.

Works with jQuery 1.9.1 and jQuery UI 1.10.3 (untested with other versions).

Define the dialog configuration options as indicated below. And enjoy.

$( "#dialog1" ).dialog({
  autoOpen: false,
  // Regular jQuery dialog options
  show: {
  effect: "fade",
  duration: 1000
  },
  hide: {
  effect: "fade",
  duration: 1000
  },
  // Add the 2 options below to use click outside feature
  clickOutside: true, // clicking outside the dialog will close it
  clickOutsideTrigger: "#opener1"  // Element (id or class) that triggers the dialog opening 
});

Any click outside the dialog or the element that triggers the dialog opening will close it.
