界面后臺：
復制代碼 代碼如下:
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)
{
//綁定界面
DataBindWindows(strLike);
}
}
/// <summary>
/// 綁定所有界面
/// </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);
//綁定界面信息
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);
//獲得路徑
string strURL = rows[0]["WindowsURL"].ToString ();
strURL = "../../" + strURL;
frmWindows.Attributes["src"]=strURL;
frmUpdateDIV.Attributes["src"] = "AdmUpdateDIV.aspx?WindowsID='" + strWindowsId + "'";
}
}
}
JS：
復制代碼 代碼如下:
var WindowsID;
function WindowsInfo() {
//獲取ifrm
var frmWindows = document.getElementById("frmWindows").contentWindow;
//獲取界面ID
WindowsID = document.getElementById("DdlWindowsName").value;
var rootboxs = frmWindows.document.getElementById("main");
var child = rootboxs.childNodes;
findchildbox(child);
};
//搜尋子節點
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();
//為了兼容部分Mozillar瀏覽器,當來自服務器響應開頭不是xml，導致的無法響應問題
if (xmlhttp.overrideMimeType) {
xmlhttp.overrideMimeType('text/xml');
}
}
else if (window.ActiveXObject) {
//IE5\IE6
xmlhttp = new activeXObject("Microsoft.XMLHTTP");
}
if (xmlhttp == null || xmlhttp == undefined) {
alert("con't create XMLHttpRequest Object");
}
////注冊回調函數
//xmlhttp.onreadystatechange = callback;
//發送信息
xmlhttp.open('GET', '../../Manager/RoleManager/AddBox.ashx?childboxId=' + childboxId + '&childboxTitle=' + childboxTitle + '&parentboxId=' + parentboxId+'&windowsId='+WindowsID, true);
xmlhttp.send(null);
//function callback() {
// //判斷交互是否完成,是否正確返回
// if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
// }
//}
}
findchildbox(parentNode[i].childNodes)
}
}
//查詢父節點
function findparentbox(child) {
if (child.nodeName == "BOX") {
return child;
} else {
return findparentbox(child.parentNode)
}
}
一般處理程序：
復制代碼 代碼如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using BLL.Manager.RoleUserManagerBLL;
using System.Data;
using System.Text;
using Model;
using BLL;
namespace ExamSystemV3.Manager.RoleManager
{

{

DIVEntity EDiv = new DIVEntity();
TR_WindowsDIVEntity EWindowsDiv = new TR_WindowsDIVEntity();
AdmDIVManager admDIVManager = new AdmDIVManager();
PublicBLL publicBll = new PublicBLL();
///收集信息
string strChildBoxId = "";

string strWindowsId = context.Request.QueryString["windowsId"].ToString().Trim();
string strParentBoxId=context.Request.QueryString["parentboxId"].ToString ().Trim();;
string strState = "是";
string strDateTime = publicBll.GetDate();
string strIP = publicBll.GetWebClientIp();
string strOperator ="xvshu";//context.Session["UserNo"].ToString().Trim(); ;
//給實體類賦值
EDiv.Id = strChildBoxId;
EDiv.MainRelation = strParentBoxId;
EDiv.DIVName = strChildBoxTitle;
EDiv.DIVDescribe = strChildBoxTitle;
EDiv.Operator = strOperator;
EDiv.OperatorIP = strIP;
EDiv.State = strState;
EDiv.DateTime = strDateTime;
//給WindowsDIV實體類賦值
EWindowsDiv.DIVID = strChildBoxId;
EWindowsDiv.WindowsID = strWindowsId;
EWindowsDiv.IsVisible = "是";
EWindowsDiv.Operator = strOperator;
EWindowsDiv.OperatorIP = strIP;
EWindowsDiv.DateTime = strDateTime;
//添加DIV
admDIVManager.AddDIV(EDiv,EWindowsDiv);
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
