>joomla- 如何从页面中删除不需要的js文件
我使用过一些页面的插件，所以所有页面都包含许多js文件
我知道有两种方法：
1( 如果文档对象并删除 js 文件，则获取一个实例(您可以在插件中执行此操作(：
<?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( 直接从模板索引中删除 JS 文件.php ：
<?php unset($this->_scripts['/media/system/js/mootools-core.js']); ?>
如果你想删除Joomla添加的所有脚本，包括内联脚本，最快的方法是：
$this->_script = $this->_scripts = array();
将其添加到模板文件中<head>部分上方的任何位置。
您可以简单地编辑这些插件代码来删除这些文件。 或者卸载这些插件(如果不需要(。
**An easiest way to disable mootools/ unwanted javascripts for your site in joomla cms ( 2.5 version )**(still loads it for your admin)
**Step-1:**
Using your favorite file editor, open for edit:
libraries/joomla/document/html/renderer/head.php
**Step-2:** check for code in head.php
// Generate script file links
foreach ($document->_scripts as $strSrc => $strAttr)
{
// *** start *** //
$ex_src = explode("/",$strSrc);
$js_file_name = $ex_src[count($ex_src)-1];
$js_to_ignore = array("mootools-more.js","core.js"); // scripts to skip loading
//skip loading scripts..
if( in_array($js_file_name,$js_to_ignore) AND substr_count($document->baseurl,"/administrator") < 1 AND $_GET['view'] != 'form'){continue;}
// *** end *** //
**Step-3:**
Clear cache & refresh page.
