-# Introduction
-
-Behaviour-driven JavaScript library, customized for usage in SilverStripe CMS.
-
-Caution: Seriously outdated, consider using [http://github.com/hafriedlander/jquery.entwine](jQuery.entwine) and [http://api.jquery.com/live/](jQuery.live) instead.
-
-# Author
-
- * Sam Minnee (sam at silverstripe dot com)
-
-# Requirements
-
- * Custom Prototype 1.4 RC3 (see `framework/thirdparty/prototype/prototype.js`)
-
-# Tutorial
-
-In SilverStripe, I've tried to make Javascript development a lot more well-structured. It's very easy to write spaghetti, but this ultimately prevents maintainability. This page is a guide to better Javascript. (hopefully).
-
-## Required includes
-
-To use everything mentioned here, first include jsparty/behaviour.js and jsparty/prototype.js. This is a lot of overhead, I know, and producing a leaner core file is definitely on the to do list!
-
-## Class creation and inheritance
-
-Classes in Javascript are normally too voodoo to be consistently applied. I've created some libraries to help this.
- * Class.create() will return a new class.
- * Class.extend(parentClassName) will return a class that extends form the parent class.
- * Class.extend(parentClass1).extend(parentClass2) will perform multiple inheritance.
-
-Once we've created our classes, then what? You should define the prototype, as indicated below. The initialize method acts as the constructor. The parent constructor is automatically called **before** the child constructor.
-
-If you would like to access a parent class' method within a child class, you can refer to this.ParentClassName.methodName(). This is useful if you've overloaded the method but want to base its functionality on the parent method.
-
-### Automatic instantiation
-
-This is where things get a even more fruity. We have the power to automatically configure DOM objects - the tags within your HTML - to automatically act as your. This lets you build "intelligence" into the elements on your page - not only overriding event handlers, but creating methods that can be called by other objects throughout the application. Although my experience so far is a little limited, it seems as though this is a much cleaner way of coding our javascript.
-
-The thing to remember - the thing which differs from many other Javascript coding styles - is that the DOM object and the "control" object **are one and the same**.
-
-Each class will have an applyTo() method. This method can be passed either a **CSS selector** or an element. If you call applyTo() before the page is loaded, the class will be applied in the window.onload() event.
-
-#### Example
-
-here's how you roll it all together in an example.
-
- Resizable = Class.create();
- onmousedown : function() {
- ...
- },
- onmouseup : function() {
- ...
- }
- }
-
- SidePanel = Class.create();
- SidePanel.prototype = {
- initialize : function() {
- ...
- },
- onshow : function() {
- ...
- },
- onresize : function() {
- ...
- },
- ajaxGetPanel : function(onComplete) {
- ...
- },
- afterPanelLoaded : function() {
- }
- }
-
- VersionList = Class.extend('SidePanel').extend('Resizable');
- VersionList.prototype = {
- afterPanelLoaded : function() {
- ...
- }
- }
-
- VersionItem.applyTo('#versions//holder tbody tr');
- VersionAction.applyTo('#versions//holder p.pane//actions');
- VersionList.applyTo('#versions//holder');
-
-CAUTION: If you want to to have true instance-variables, specify them in initialize() instead of making a new object-property.
-
-
- Resizable = Class.create();
- staticVar: "the same in each instance",
-
- initialize: function() {
- this.instanceVar = "current dom-id: " + this.id;
- }
- }
- Resizable.applyTo("div.multipleElements");
