Yii - 使缩小可配置的最佳方法

Question

I am using minscript extension for Javascript and CSS minification on my site. I have the following code in my protected/config/main.php

'clientScript'=>array(
    'class'=>'ext.minScript.components.ExtMinScript',
)

In one of the modules I need custom implementation of CClientScript class. So I made a new class and derived it from ExtMinScript, like this.

class BaseClientScript extends ExtMinScript

In the module initialization code, I use setComponent to "overwrite" the "clientScript" component from main configuration. Thus I get the minification implementation from ExtMinScript and my implementation in BaseClientScript.

If I want to disable minification in the module, I change the code to derive BaseClientScript from CClientScript.

class BaseClientScript extends CClientScript

Now I want minification to be configurable in the main configuration. (protected/config/main.php)

I can make two classes, one deriving from CClientScript and other from ExtMinScript. (BaseClientScript and BaseMinClientScript) I don't want to do that, as that would mean that I have duplicate my custom client-script implementation in two classes.

Is there a better way to handle this situation?

Answer 1

Use a technique like this:

 define('MinClientScriptClass', 'CClientScript');

when you want to use minification in protected/config/main.php

and write this in BaseClientScript:

if (defined('MinClientScriptClass')) {

    class MinClientScriptClass extends CClientScript {}

} else {

    class MinClientScriptClass extends ExtMinScript {}
}

class BaseClientScript extends MinClientScriptClass

NOTE: When you want to disable minification just comment the define in main config. Or use config params in main.php, and config true/false value check in if above.
