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：
Default.aspx

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 function setCookie(name, value, expires, path, domain, secure) { var today = new Date(); today.setTime(today.getTime()); if (expires) { expires = expires * 1000 * 60 * 60 * 24; } var expires_date = new Date(today.getTime() + (expires)); document.cookie = name + '=' + escape(value) + ((expires) ? ';expires=' + expires_date.toGMTString() : '') + ((path) ? ';path=' + path : '') + ((domain) ? ';domain=' + domain : '') + ((secure) ? ';secure' : ''); } //读取菜单 function getCookie(name) { if (document.cookie.length > 0) { cookieStart = document.cookie.indexOf(name + "=") if (cookieStart != -1) { cookieStart = cookieStart + name.length + 1 cookieEnd = document.cookie.indexOf(";", cookieStart) if (cookieEnd == -1) cookieEnd = document.cookie.length return unescape(document.cookie.substring(cookieStart, cookieEnd)) } } return "" } //初始化菜单 function onload() { var width = document.body.clientWidth - 207;

} function jumpto(inputurl) { if (document.getElementById && displaymode == 0) document.getElementById("main_right").src = inputurl else if (document.all && displaymode == 0) document.all.external.src = inputurl; else { if (!window.win2 || win2.closed) win2 = window.open(inputurl); else { } } } //创建菜单缓存 function CreateSideBarCookie() { var SideBarKey = document.getElementById("left").src.substring(document.getElementById("left").src.lastIndexOf('/') + 1, document.getElementById("left").src.lastIndexOf('.')); var SideBarValue; if (document.getElementById("frmTitle")) { if (SideBarValue = document.getElementById("frmTitle").style.display == "") { SideBarValue = "block"; } else { SideBarValue = document.getElementById("frmTitle").style.display; } } var existentSideBarCookie = getCookie("SideBarCookie"); if (SideBarKey.length != 0 && SideBarValue.length != 0) { var temp = ""; var SideBarKV = existentSideBarCookie; if (existentSideBarCookie.length != 0) { if (SideBarKV.indexOf(SideBarKey) != -1) { var arrKV = existentSideBarCookie.split("&"); for (var v in arrKV) { if (arrKV[v].indexOf(SideBarKey) != -1) { temp = existentSideBarCookie.replace(arrKV[v], SideBarKey + "=" + SideBarValue); } } } else { temp = SideBarKey + "=" + SideBarValue + "&" + existentSideBarCookie; } } else { temp = SideBarKey + "=" + SideBarValue; } setCookie("SideBarCookie", temp, 300, "/", "", false); } else { return ""; } } //恢复菜单 function InitSideBarState() { var existentSideBarCookie = getCookie("SideBarCookie");

document.getElementById("main_right").style.height = height; document.getElementById("main_right").style.width = width; document.getElementById("FrameTabs").style.width = width; if (CheckFramesScroll) { CheckFramesScroll(); } } else { obj.alt = "关闭左栏"; obj.src = "Images/butClose.gif"; document.getElementById("frmTitle").style.display = "block"; onload(); } } //显示菜单及内容 function ShowMain(FileName_Left, FileName_Right) { var temp; if (FileName_Left != "") { var checkLeftUrl = CheckCurrentLeftUrl(FileName_Left); if (checkLeftUrl == "false") { temp = document.getElementById("left"); temp.src = FileName_Left + GetUrlParm(FileName_Left); temp.contentWindow.window.name = "left"; frames["left"] = temp.contentWindow.window; } } if (FileName_Right != "") { temp = document.getElementById("main_right"); temp.src = FileName_Right + GetUrlParm(FileName_Right); temp.contentWindow.window.name = "main_right"; frames["main_right"] = temp.contentWindow.window; } InitSideBarState(); } function CheckCurrentLeftUrl(leftUrl) { var src = document.getElementById("left").src; var regex = /\s*[\?&]{1,1}t=[0-9]{1,}$/; var currentLeftUrl = src.replace(regex, ''); if (currentLeftUrl.lastIndexOf(leftUrl) >= 0) { if (currentLeftUrl.lastIndexOf(leftUrl) == (currentLeftUrl.length - leftUrl.length)) { return "true"; } } return "false"; } function GetUrlParm(url) { var urlparm = "?"; if (url.indexOf('?') >= 0) { urlparm = "&"; } urlparm = urlparm + "t=" + GetRandomNum(); return urlparm; } function GetRandomNum() { var Range = 1000; var Rand = Math.random(); return (Math.round(Rand * Range)); } function switchSysBar() { var obj = document.getElementById("switchPoint"); if (obj.alt == "关闭左栏") { obj.alt = "打开左栏"; obj.src = "/Images/butOpen.gif"; document.getElementById("frmTitle").style.display = "none"; var width, height; width = document.body.clientWidth - 12; height = document.body.clientHeight - 70; document.getElementById("main_right").style.height = height;

if (tID != "") { document.getElementById("A" + tID).style.backgroundImage = "url(/Images/digital_left.gif)"; if (document.getElementById("A" + tID).childNodes.length < 2) { document.getElementById("Span" + tID).style.backgroundImage = "url(/Images/digital_side.gif)"; } else { document.getElementById("Span" + tID).style.backgroundImage = "none"; if (triangle) { triangle.style.backgroundImage = "none"; } } document.getElementById("Span" + tID).className = "digitaltext"; } document.getElementById("A" + ID).style.backgroundImage = "url(/Images/seg_left.gif)"; if (document.getElementById("A" + ID).childNodes.length < 2) { document.getElementById("Span" + ID).style.backgroundImage = "url(/Images/seg_side.gif)";

if (triangle) { triangle.style.backgroundImage = "url(/Images/seg_side.gif)"; } } document.getElementById("Span" + ID).className = "segtext"; tID = ID; } }
完成之后再加入菜单，如下html：
menu.aspx

"" : "none"; } } } function keylock(evt) { if((evt.keyCode == 13) && (this.OpenMainRight)) { this.OpenMainRight(); } } String.prototype.trim = function() { // 用正则表达式将前后空格 // 用空字符串替代。 return this.replace(/(^\s*)|(\s*$)/g, ""); } </script> <style type="text/css"> <!-- .skin1 {}{ cursor:default; font:menutext; position:absolute; text-align:left; font-family: Arial, Helvetica, sans-serif; font-size: 10pt; width:120px; background-color:#cccccc; border:1 solid buttonface; visibility:hidden; border:2 outset buttonhighlight; } .menuitems {}{ padding-left:15px; padding-right:10px; } --> </style> </head> <body id="Guidebody" onkeydown="keylock(event)"> <form name="aspnetForm" method="post" action="" id="aspnetForm"> <div id="Guide_back"> <ul> <li id="Guide_top"> <div id="Guide_toptext"> 系统管理 </div> </li> <li id="Guide_main"> <div id="Guide_box"> <div class="guideexpand" onclick="Switch(this)"> 系统管理</div> <div class="guide"> <ul> <li><a href="temp.htm" target="main_right">用户与权限</a></li> <li><a href="temp.htm" target="main_right">管理员配置</a></li> <li><a href="temp.htm" target="main_right">基础数据</a></li> <li><a href="temp.htm" target="main_right">编号规则</a></li> <li><a href="temp.htm" target="main_right">公司信息</a></li> <li><a href="temp.htm" target="main_right">员工信息</a></li> <li><a href="temp.htm" target="main_right">部门信息</a></li> <li><a href="temp.htm" target="main_right">修改密码</a></li> <li><a href="temp.htm" target="main_right">个性配置</a></li> <li><a href="temp.htm" target="main_right">网格颜色配置</a></li> <li><a href="temp.htm" target="main_right">合同多级分类</a></li> <li><a href="temp.htm" target="main_right">标准业务问题分类</a></li> <li><a href="temp.htm" target="main_right">商品多级分类</a></li> <li><a href="temp.htm" target="main_right">合同模板分类</a></li> <li><a href="temp.htm" target="main_right">文件分类</a></li> <li><a href="temp.htm" target="main_right">收支科目分类</a></li> <li><a href="temp.htm" target="main_right">数据导入</a></li> <li><a href="temp.htm" target="main_right">数据反审核</a></li> <li><a href="temp.htm" target="main_right">业务移交</a></li> <li><a href="temp.htm" target="main_right">退出系统</a></li> </ul> </div> </div> </li> <li id="Guide_bottom"></li> </ul> </div> </form> </body> </html>
这样完成后基本内容就实现了，然后根据自己的喜好和网站的风格美化一下就完成了。
