/**
|
|
* jQuery plugin for Pretty looking right click context menu.
|
|
*
|
|
* Requires popup.js and popup.css to be included in your page. And jQuery, obviously.
|
|
*
|
|
* Usage:
|
|
*
|
|
* $('.something').contextPopup({
|
|
* title: 'Some title',
|
|
* items: [
|
|
* {label:'My Item', icon:'/some/icon1.png', action:function() { alert('hi'); }},
|
|
* {label:'Item #2', icon:'/some/icon2.png', action:function() { alert('yo'); }},
|
|
* null, // divider
|
|
* {label:'Blahhhh', icon:'/some/icon3.png', action:function() { alert('bye'); }, isEnabled: function() { return false; }},
|
|
* ]
|
|
* });
|
|
*
|
|
* Icon needs to be 16x16. I recommend the Fugue icon set from: http://p.yusukekamiyamane.com/
