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：

AdminIndex.jsvar 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; };
