joomla- 如何从页面中删除不需要的 js 文件

joomla- How to remove unwanted js files from page

我在一些页面使用了插件，所以所有页面都包含了很多js文件

I have used plugins some pages so many js files are included in all pages

推荐答案

我知道有两种方法:

1) 获取文档对象的实例并删除 js 文件(您可以在插件中执行此操作):

1) get an instance if the document object and remove the js files (you could do that in a plugin) : 

<?php 
         //get the array containing all the script declarations
         $document = JFactory::getDocument(); 
         $headData = $document->getHeadData();
         $scripts = $headData['scripts'];

         //remove your script, i.e. mootools
         unset($scripts['/media/system/js/mootools-core.js']);
         unset($scripts['/media/system/js/mootools-more.js']);
         $headData['scripts'] = $scripts;
         $document->setHeadData($headData);
?>

2) 直接从模板 index.php 中删除 js 文件:

2) remove js files directly from your templates index.php :

<?php unset($this->_scripts['/media/system/js/mootools-core.js']); ?>
