上一篇博客中有些没有考虑到的东西这次更改一下代码如下：
界面前台：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AdmShowDIV.aspx.cs" Inherits="ExamSystemV3.Manager.RoleManager.AdmShowDIV" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="Author" content="kudychen@gmail.com" /> <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> <title></title> <script src="../../js/DIV/jquery.js" type="text/javascript"></script> <script src="../../js/DIV/DIV.js" type="text/ecmascript"></script> <link href="../../css/admin.global.css" rel="stylesheet" type="text/css" /> <link href="../../css/admin.content.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="../../../js/jquery.easyui.min.js"></script> <script type="text/javascript" src="../../js/jquery-1.4.2.min.js"></script> <script type="text/javascript" src="../../js/jquery.utils.js"></script> <link href="../../jBox/Skins/Green/jbox.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="../../jBox/jquery.jBox-2.3.min.js"></script> <script type="text/javascript" src="../../js/admin.js"></script> <script type="text/javascript" src="../../js/SimpleTree.js"></script> </head> <body> <form id="form1" runat="server"> <div class="container"> <div class="location">当前位置：界面元素管理 -> 查看界面元素</div> <div class="blank10"></div> <div class="search block"> <div class="h"> <span class="icon-sprite icon-magnifier"></span> <h3>快速搜索</h3> </div> <div class="tl corner"></div><div class="tr corner"></div><div class="bl corner"></div><div class="br corner"></div> <div class="cnt-wp"> <div class="cnt"> <div class="search-bar" id="SelectRole"> <label class="txt-green">请选择界面：</label> <asp:DropDownList ID="DdlWindowsName" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DdlWindowsName_SelectedIndexChanged"> </asp:DropDownList> <a class="btn-lit" href="#" onclick="WindowsInfo()"><span>扫描界面信息</span></a> </div> </div> </div> </div> </div> <div class="block"> <div class="h"> <span class="icon-sprite icon-list"></span> <h3>界面详情</h3> </div> <div class="tl corner"></div> <div class="tr corner"></div> <div class="bl corner"></div> <div class="br corner"></div> <div class="cnt-wp"> <div class="cnt"> <iframe id="frmWindows" runat="server" frameborder="0" marginheight="0" marginwidth="0" scrolling="auto" style=" display: inline; height: 400px;" width="75%" ></iframe> <iframe id="frmUpdateDIV" runat="server" frameborder="0" marginheight="0" marginwidth="0" scrolling="auto" style="display: inline; height: 400px; 24%;"></iframe> </div> </div> </div> </form> </body> </html>
界面后台：
using BLL.Manager.RoleUserManagerBLL; using System; using System.Collections.Generic; using System.Data; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace ExamSystemV3.Manager.RoleManager { public partial class AdmShowDIV : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string strLike=""; if (!IsPostBack) { //绑定界面 DataBindWindows(strLike); } } /// <summary> /// 绑定所有界面 /// </summary> /// <param name="strLike"></param> public void DataBindWindows(string strLike) { DataTable dt = new DataTable(); AdmWindowsManager admWindowsManager = new AdmWindowsManager(); //查出所有的界面 dt = admWindowsManager.QueryWindowInfo(strLike); //绑定界面信息 DdlWindowsName.DataSource = dt; DdlWindowsName.DataValueField = "Id"; DdlWindowsName.DataTextField = "WindowsName"; DdlWindowsName.DataBind(); } protected void DdlWindowsName_SelectedIndexChanged(object sender, EventArgs e) { DataTable dt = new DataTable(); string strLike = ""; AdmWindowsManager admWindowsManager = new AdmWindowsManager(); //查出界面的信息 dt = admWindowsManager.QueryWindowInfo(strLike); string strWindowsId=DdlWindowsName.SelectedValue.ToString().Trim(); strLike = "Id='"+strWindowsId+"'"; DataRow[] rows =dt.Select (strLike); //获得路径 string strURL = rows[0]["WindowsURL"].ToString (); strURL = "../../" + strURL; frmWindows.Attributes["src"]=strURL; frmUpdateDIV.Attributes["src"] = "AdmUpdateDIV.aspx?WindowsID='" + strWindowsId + "'"; } } }
JS：
var WindowsID; function WindowsInfo() { //获取ifrm var frmWindows = document.getElementById("frmWindows").contentWindow; //获取界面ID WindowsID = document.getElementById("DdlWindowsName").value; var rootboxs = frmWindows.document.getElementById("main"); var child = rootboxs.childNodes; findchildbox(child); }; //搜寻子节点 function findchildbox(parentNode) { for (var i = 0; i < parentNode.length; i++) { if (parentNode[i].nodeName == "BOX") { var childboxId = parentNode[i].id; var childboxTitle = encodeURI(parentNode[i].title); var parentbox = findparentbox(parentNode[i].parentNode); var parentboxId = parentbox.id; if (window.XMLHttpRequest) { //IE7 above,firefox,chrome^^ xmlhttp = new XMLHttpRequest(); //为了兼容部分Mozillar浏览器,当来自服务器响应开头不是xml，导致的无法响应问题 if (xmlhttp.overrideMimeType) { xmlhttp.overrideMimeType('text/xml'); } } else if (window.ActiveXObject) { //IE5IE6 xmlhttp = new activeXObject("Microsoft.XMLHTTP"); } if (xmlhttp == null || xmlhttp == undefined) { alert("con't create XMLHttpRequest Object"); } ////注册回调函数 //xmlhttp.onreadystatechange = callback; //发送信息 xmlhttp.open('GET', '../../Manager/RoleManager/AddBox.ashx?childboxId=' + childboxId + '&childboxTitle=' + childboxTitle + '&parentboxId=' + parentboxId+'&windowsId='+WindowsID, true); xmlhttp.send(null); //function callback() { // //判断交互是否完成,是否正确返回 // if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { // } //} } findchildbox(parentNode[i].childNodes) } } //查询父节点 function findparentbox(child) { if (child.nodeName == "BOX") { return child; } else { return findparentbox(child.parentNode) } }
一般处理程序：
