列表頁面指向

在引用公共html頁面時,爲了便於知道當前所處的頁面,咱們每每在當前的頁面採用特定的樣式(如在當前頁面的列表中加active class),實現原理是當a 的href的屬性與document.location.href一致時在a 所在的列表中增長active classjavascript

<html>

 <body>
  <li class="treeview"> <a href="#"> <i><img src="../../dist/img/admin-shezhi.png" width="20" height="20" /></i> <span>系統設置</span> <i class="fa fa-angle-left pull-right"></i> </a> 
   <ul class="treeview-menu">
