更改 yii 中已注册脚本文件的顺序 [英] Change order of registered script files in yii

问题描述

我正在为 Yii 应用程序制作一个小部件.主布局视图注册了所有常见的脚本文件，例如 jQuery 和 jQueryUI.在我的小部件中，我想使用一个 jQueryUI 插件，该插件依赖于已加载的 jQueryUI.

I'm making a widget for a Yii application. The main layout view registers all the common script files such as jQuery and jQueryUI. In my widget I want to use a jQueryUI plugin that relies on jQueryUI already being loaded.

我知道我可以指定将脚本包含在页面上的哪个位置，但是将它简单地包含在末尾"似乎有点意外 - 如果我有其他脚本需要在该插件之后加载怎么办?我如何确保它们以正确的顺序加载 - 有人有任何想法吗?

I know I can specify where on the page the script is included, but it seems a bit hit and miss to simply include it at the "end" - what if I have other script that I need to load after that plugin? How do I ensure they're loaded in the right order - anyone got any ideas?

推荐答案

你可以使用 Yii 中的依赖特性 脚本包.我之前遇到过类似的问题.

You can use the dependency feature in Yii script packages. I was having similar problem before.

例如你有如下的脚本包配置，

For example you have script packages config like below,

'clientScript' => array(
  'packages' => array(
     'package1' => array(
          'basePath' => 'path.to.package1',
          'js' => array(
              'package1.js',
          ),
          'css' => array(
              'package1.css'
          ),
      ),
     'package2' => array(
          'basePath' => 'path.to.package2',
          'js' => array(
              'package2.js',
          ),
          'css' => array(
              'package2.css'
          ),
          'depends' => array(
                'package1',
          )
      ),
     'package3' => array(
          'basePath' => 'path.to.package3',
          'js' => array(
              'package3.js',
          ),
          'css' => array(
              'package3.css'
          ),
          'depends' => array(
                'package2',
          )
      ),
   )
)

在上面的示例中，package2 需要(取决于)package1 和 package3 需要 package2.假设在您的情况下，一个小部件使用 package2，另一个脚本使用 package3.即使你不渲染widget，如果你使用Yii::app()->clientScript->registerPackage('package3');，它会自动安装package2 然后在 package2 之前安装 package1 (或者如果之前某些脚本已经需要 package1 则不会安装.).

In sample above, package2 requires (depends) package1 and package3 requires package2. Let's say in your case, a widget uses package2, and the other script uses package3. Even if you don't render the widget, if you use Yii::app()->clientScript->registerPackage('package3');, it will automatically install the package2 which then install the package1 before package2 (or won't install if the package1 is already required by some scripts before.).
