        首先在页面上引用css文件和js文件，css文件一般在&lt;head&gt;中添加，js文件一般在&lt;/body&gt;之前添加。注意要先引用jquery和jquery.mCustomScrollbar，再引用该js。<br>
        Firstly reference the css and js file of this plugin, the best location of the css reference is in &lt;head&gt;,
        and the js is before &lt;/body&gt;, make sure the js follows jQuery and jquery.mCustomScrollbar.
