属性详细

corePackages 属性 （可用自 v1.1.7） public array $corePackages;

list of core script packages (name=>package spec). Please refer to packages for details about package spec.

By default, the core script packages are specified in 'framework/web/js/packages.php'. You may configure this property to customize the core script packages.

When calling registerPackage to register a script package, packages will be checked first followed by this property. If a package is found, it will be registered for rendering later on.

coreScriptPosition 属性 （可用自 v1.1.3） public integer $coreScriptPosition;

Where the scripts registered using registerCoreScript or registerPackage will be inserted in the page. This can be one of the CClientScript::POS_* constants. Defaults to CClientScript::POS_HEAD.

coreScriptUrl 属性 public string getCoreScriptUrl()
public void setCoreScriptUrl(string $value)

Returns the base URL of all core javascript files. If the base URL is not explicitly set, this method will publish the whole directory 'framework/web/js/source' and return the corresponding URL.

coreScripts 属性 （可用自 v1.1.7） protected array $coreScripts;

the registered script packages (name => package spec)

css 属性 （可用自 v1.1.3） protected array $css;

the registered css code blocks (key => array(CSS code, media type)).

cssFiles 属性 protected array $cssFiles;

the registered CSS files (CSS URL=>media type).

enableJavaScript 属性 public boolean $enableJavaScript;

whether JavaScript should be enabled. Defaults to true.

hasScripts 属性 （可用自 v1.1.7） protected boolean $hasScripts;

whether there are any javascript or css to be rendered.

linkTags 属性 （可用自 v1.1.3） protected array $linkTags;

the registered head link tags. Each array element represents an option array that will be passed as the last parameter of CHtml::linkTag.

metaTags 属性 （可用自 v1.1.3） protected array $metaTags;

the registered head meta tags. Each array element represents an option array that will be passed as the last parameter of CHtml::metaTag.

packages 属性 （可用自 v1.1.7） public array $packages;

list of custom script packages (name=>package spec). This property keeps a list of named script packages, each of which can contain a set of CSS and/or JavaScript script files, and their dependent package names. By calling registerPackage, one can register a whole package of client scripts together with their dependent packages and render them in the HTML output.

The array structure is as follows:

array('package-name'=>array(  'basePath'=>'alias of the directory containing the script files',  'baseUrl'=>'base URL for the script files',  'js'=>array(list of js files relative to basePath/baseUrl),  'css'=>array(list of css files relative to basePath/baseUrl),  'depends'=>array(list of dependent packages),),......
)

The JS and CSS files listed are relative to 'basePath'. For example, if 'basePath' is 'application.assets', a script named 'comments.js' will refer to the file 'protected/assets/comments.js'.

When a script is being rendered in HTML, it will be prefixed with 'baseUrl'. For example, if 'baseUrl' is '/assets', the 'comments.js' script will be rendered using URL '/assets/comments.js'.

If 'baseUrl' does not start with '/', the relative URL of the application entry script will be inserted at the beginning. For example, if 'baseUrl' is 'assets' and the current application runs with the URL 'http://localhost/demo/index.php', then the 'comments.js' script will be rendered using URL '/demo/assets/comments.js'.

If 'baseUrl' is not set, the script will be published by CAssetManager and the corresponding published URL will be used.

When calling registerPackage to register a script package, this property will be checked first followed by corePackages. If a package is found, it will be registered for rendering later on.

scriptFiles 属性 protected array $scriptFiles;

the registered JavaScript files (position, key => URL)

scriptMap 属性 public array $scriptMap;

the mapping between script file names and the corresponding script URLs. The array keys are script file names (without directory part) and the array values are the corresponding URLs. If an array value is false, the corresponding script file will not be rendered. If an array key is '*.js' or '*.css', the corresponding URL will replace all JavaScript files or CSS files, respectively.

This property is mainly used to optimize the generated HTML pages by merging different scripts files into fewer and optimized script files.

scripts 属性 protected array $scripts;

the registered JavaScript code blocks (position, key => code)
