JQuery实现经典网站后台框架[动易程序改版] 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 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ContractSystem.WebUI.Default" %> 零码软件服务（www.learnmark.com） [removed][removed] [removed][removed] [removed][removed] 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)); [removed] = name + '=' + escape(value) + ((expires) ? ';expires=' + expires_date.toGMTString() : '') + ((path) ? ';path=' + path : '') + ((domain) ? ';domain=' + domain : '') + ((secure) ? ';secure' : ''); } //读取菜单 function getCookie(name) { if ([removed].length > 0) { cookieStart = [removed].indexOf(name + "=") if (cookieStart != -1) { cookieStart = cookieStart + name.length + 1 cookieEnd = [removed].indexOf(";", cookieStart) if (cookieEnd == -1) cookieEnd = [removed].length return unescape([removed].substring(cookieStart, cookieEnd)) } } return "" } //初始化菜单 function onload() { var width = document.body.clientWidth - 207; var lHeight = document.body.clientHeight - 78; var rHeight = lHeight - (jQuery("#FrameTabs").height() || 0); document.getElementById("main_right").style.width = width > 0 ? width : 0; document.getElementById("left").style.height = lHeight > 0 ? lHeight : 0; } 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"); var SideBarKey = document.getElementById("left").src.substring(document.getElementById("left").src.lastIndexOf('/') + 1, document.getElementById("left").src.lastIndexOf('.')); if (existentSideBarCookie.length != 0 && SideBarKey.length != 0 && existentSideBarCookie.indexOf(SideBarKey) != -1) { var arrKV = existentSideBarCookie.split("&"); for (var v in arrKV) { if (arrKV[v].indexOf(SideBarKey) != -1) { var currentValue = arrKV[v].split("="); ChangeSideBarState(currentValue[1]); } } } else { var obj = document.getElementById("switchPoint"); obj.alt = "关闭左栏"; obj.src = "Images/butClose.gif"; document.getElementById("frmTitle").style.display = "block"; onload(); } } //显示或隐藏菜单 function ChangeSideBarState(temp) { var obj = document.getElementById("switchPoint"); if (temp == "none") { 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; 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; 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 = ""; onload(); } CreateSideBarCookie(); } //设置选中菜单样式 var tID = ""; function ShowHideLayer(ID) { if (ID != tID) { var triangle = document.getElementById("MenuMyDeskTopMore_Triangle"); 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 (tID != "" && document.getElementById("A" + tID).childNodes.length >= 2) { if (triangle) { triangle.style.backgroundImage = "url(/Images/digital_side.gif)"; } } } else { document.getElementById("Span" + ID).style.backgroundImage = "none"; 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 快捷导航 [removed] function JumpToMainRight(url) { parent.frames["main_right"].location = url; } function ReloadMainRight() { parent.frames["main_right"].location.reload(); } function Switch(obj) { obj.className = (obj.className == "guideexpand") ? "guidecollapse" : "guideexpand"; var nextDiv; if (obj.nextSibling) { if(obj.nextSibling.nodeName=="DIV") { nextDiv = obj.nextSibling; } else { if(obj.nextSibling.nextSibling) { if(obj.nextSibling.nextSibling.nodeName=="DIV") { nextDiv = obj.nextSibling.nextSibling; } } } if(nextDiv) { nextDiv.style.display = (nextDiv.style.display != "") ? "" : "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, ""); } [removed] 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。 ...展开收缩
