网站后台是每个网站必须的部分，使用一个好的框架也是给用户良好体验的一部分内容，本文将给大家介绍使用JQuery和JS实现的ASP.NET网站后台框架。
首先看看我们需要的资源：
1. FrameTab.js （文章结尾提供下载）
该文件主要功能是实现一个像IE 8中Tab页一样的功能，这个可以方便用户在一个浏览器页面里打开多个某快的后台内容，以及对其进行切换
2. jquery.pack.js （文章结尾提供下载）
这个JQuery的文件大家应该很熟悉了，不做解释了。
主要的文件都在上面了，下面先来搭建主题框架，如下html代码：

以上代码是整个框架，接下来我们来写一些常用的JS，这些JS我们放在AdminIndex.js中：
AdminIndex.js
var displaymode = 0;
var StyleSheetPath, _BasePath, _adminPath, _adminName;
function setStyleSheetPath(path) { StyleSheetPath = path; }
function setBasePath(basepath, adminpath) { _BasePath = basepath; _adminPath = adminpath; }
function setAdminName(adminname) { _adminName = adminname; };
//修改IE下document.getElementById在id和name同名时的bug
if (/msie/i.test(navigator.userAgent)) //根据userAgent确定用户使用IE浏览器
{
document.nativeGetElementById = document.getElementById;
document.getElementById = function(id) {
var elem = document.nativeGetElementById(id);
if (elem) { //修改后的确认能得到id属性方法
if (elem.attributes['id'].value == id) {
return elem;
} else { //如果没有ID相同的,那么就遍历所有元素的集合找到id相同的元素
for (var i = 1; i < document.all[id].length; i++) {
if (document.all[id][i].attributes['id'].value == id) {
return document.all[id][i];
}
}
}
}
return null;
};
}
//存储菜单

完成之后再加入菜单，如下html：
menu.aspx
