View Class
ludoJS View
Basic view class in ludoJS. All other views inherits properties from this class. It can be
used at it is or used as ancestor for new modules.
The View class is also default type when adding children without a specified "type" attribute.
When a Component is created it executes the following life cycle methods. If you extend a component, do not
override MooTools constructor method initialize(). Instead, extend one or more of the lifeCycle method
below:
ludoConfig(config) - This is where config properties are being parsed. At this point, the DOM
container and DOM body has been created but not inserted into the page.
ludoDOM() - The main DOM of the component has been created
ludoCSS() - A method used to apply CSS styling to DOM elements.
ludoEvents() - The place to add events
ludoRendered - The component is fully rendered
Constructor
View
-
config
Parameters:
-
configObject
Example:
new ludo.View({ renderTo:document.body, html : 'Hello' } Creates a standard view rendered to the <body> element of your page
...
children:[{
html : 'View 1' },
{
html : 'View 2' }
}]
...
adds two views as child of a component
ludo.myApp.View = new Class({ Extends: ludo.View, type : 'myApp.View', ludoRendered:function(){ this.setHtml('My custom component'); } } ... ... children:[{ type : 'myApp.View' }] ...
is a simple example of how to extend a view to create your own views and how to use it. *

this.getEl().adopt(myEl);
}
ludoEvents
()
