javascript - 我如何在 "Combinator"css 压缩插件中使用单个 css 文件？

Question

您好，我正在使用“Combinator”，它是一个用于压缩 js 和 css 的插件。 Combinator link and steps

根据文档他们说在 View 或布局中添加以下行

<?php $combinator->add_libs('js', array('jquery'));?> 
<?php $combinator->add_libs('css', array('styles'));?> 

但是我如何添加单个 css 文件而不是这些整个 css？

辅助类代码:

    <?php  
class CombinatorHelper extends Helper { 
    var $Vue = null; 
    var $libs = array('js' => array(), 'css' => array()); 
    var $inline_code = array('js' => array(), 'css' => array()); 
    var $basePath = null; 
    var $cachePath = null; 

    // default conf 
    private $__options = array( 
                            'js' => array( 
                                'path' => '/js', 
                                'cachePath' => '/js', 
                                'enableCompression' => true 
                            ), 
                            'css' => array( 
                                'path' => '/css', 
                                'cachePath' => '/css', 
                                'enableCompression' => false, 
                                'compression' => 'high_compression' // Can be "high_compression", "highest_compression", "low_compression", or "default"

你试过吗？

<?php $combinator->add_libs('js', array('jquery', 'other_lib', 'third_lib'));?> 

顺便说一句，如果您现在正在您的应用程序中实现 Combinator 插件，我建议您使用 Mark Story 的 AssetCompress Plugin这是最新的并且有据可查的。
