ASP.NET對(duì)HTML頁(yè)面元素進(jìn)行權(quán)限控制(三)

上一篇博客中有些沒(méi)有考慮到的東西這次更改一下代碼如下：

界面前臺(tái)：

復(fù)制代碼代碼如下:

界面后臺(tái)：

復(fù)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(fù)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(jié)點(diǎn) 
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(dāng)來(lái)自服務(wù)器響應(yīng)開(kāi)頭不是xml，導(dǎo)致的無(wú)法響應(yīng)問(wèn)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(cè)回調(diào)函數(shù) 
//xmlhttp.onreadystatechange = callback; 
//發(fā)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(jié)點(diǎn) 
function findparentbox(child) { 

if (child.nodeName == "BOX") { 
return child; 
} else { 
return findparentbox(child.parentNode) 

} 

} 

一般處理程序：

復(fù)制代碼代碼如下:

 
using System;

using System.Web; 
using BLL.Manager.RoleUserManagerBLL; 
using System.Data; 
using System.Text;

using BLL; 

namespace ExamSystemV3.Manager.RoleManager 
{ 
/// summary> 
/// AddBox 的摘要說(shuō)明 
/// /summary> 
public class AddBox : IHttpHandler 
{ 

public void ProcessRequest(HttpContext context) 
{ 
context.Response.ContentType = "text/plain"; 
System.Threading.Thread.Sleep(1000); 
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 strChildBoxTitle = ""; 
strChildBoxId = context.Request.QueryString["childboxId"].ToString().Trim(); 
strChildBoxTitle = context.Server.UrlDecode(context.Request.QueryString["childboxTitle"].ToString().Trim()); 
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(shí)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(shí)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; 
} 
} 
} 
}
