# 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Caution: Seriously outdated, consider using [http://github.com/hafriedlander/jquery.entwine](jQuery.entwine) and [http://api.jquery.com/live/](jQuery.live) instead.

# 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");
