/** |
|
* yii is the root module for all Yii JavaScript modules. |
|
* It implements a mechanism of organizing JavaScript code in modules through the function "yii.initModule()". |
|
* |
|
* Each module should be named as "x.y.z", where "x" stands for the root module (for the Yii core code, this is "yii"). |
|
* |
|
* A module may be structured as follows: |
|
* |
|
* ~~~ |
|
* yii.sample = (function($) { |
|
* var pub = { |
|
* // whether this module is currently active. If false, init() will not be called for this module |
|
* // it will also not be called for all its child modules. If this property is undefined, it means true. |
|
* isActive: true, |
|
* init: function() { |
|
* // ... module initialization code go here ... |
|
* }, |
|
* |
|
* // ... other public functions and properties go here ... |
|
* }; |
|
* |
|
* // ... private functions and properties go here ... |
|
* |
|
* return pub; |
|
* })(jQuery); |
|
* ~~~ |
|
* |
|
* Using this structure, you can define public and private functions/properties for a module. |
|
* Private functions/properties are only visible within the module, while public functions/properties |
|
* may be accessed outside of the module. For example, you can access "yii.sample.isActive". |
|
* |
|
* You must call "yii.initModule()" once for the root module of all your modules. |
