感谢所以回答问题的人。 比较好的办法是使用url传参数,然后根据参数判断是否有必要显示class

但是更好的办法是下面这段JS

1

2

3

4

$('ul.main-menu li a').each(function(){

    if($($(this))[0].href==String(window.location))

        $(this).parent().addClass('active');

});

Copy after login

详情:用jquery实现菜单导航给当前页面一个样式/

利用window.location.href增加一个判断是否为当前页的代码应该是可以做到的吧
不过感觉还是用后台代码写比较爽一点

一般来说这个还是怡红公子所说的由后台写入current后再处理比较合理。

必须要求纯前台实现的话,页面载入后需要做一次判断来决定是否对指定按钮展开/高亮。
要么用判断当前地址的方式,用地址来匹配需要处理的按钮;要么在按钮点击事件中添加把本按钮的id写到cookie里的操作函数。
前者突出“当前页”这一概念逻辑,但需要在js中额外维护一份地址-按钮对应表或对应规则。
后者就不是当前页的概念了,就是纯粹的指示,但是对禁止cookie的浏览器就无奈了。

常规的做法还是对比地址比较多,特别是按钮id与地址之间的对应关系比较简单的话。
比如 1.html -> id="btn1" 之类的……

1. 用ajax加载内容页面 , 同时打开菜单 .. 就是说页面不跳转
2. 用iframe显示内容也 , 同样页面不跳转
3. 在页面中控制 链接的样式 , 比如当前页面 是业务报表页面 , 那么就控制这个菜单 的class 为 active...类似这样吧

出个下下策:
修改addClass/removeClass等系列函数,把每次操作计入cookie,到新的页面读取cookie,把所有操作再做一遍……

iframe吧

a标签中的链接做一下处理呗,例如 /content.html ==> /content.html?tab=1

这个参数对后台没有用,但是会留在地址栏里,用window.location.href可以取到
在页面加载的过程中解析url,看看有没有tab的参数,有就addClass

鼠标点击之后修改url增加个参数¤tMenu=当前菜单的id,刷新时再判断处理

这个可以用jquery的cookie保存当前填写的需要设置的状态,然后在加载完根据cookie设置即可
