asp.net中Post表单保存页面状态并输出源码的实现方

先执行脚本,复制源码到隐藏域里,再输出源码，注意代码红色设置
Html页面
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default"
ValidateRequest="false" %>
<%@ Register Src="UserControl/Ucone.ascx" TagName="Ucone" TagPrefix="uc1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>页面提交后提取Html源码(保持状态)</title>
<script type="text/javascript">
function getAllCode_IE() {
document.getElementById("hid_html").value=document.documentElement.outerHTML;
}
function getAllCode_FireFox(){
return document.body.innerHTML.toString();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<uc1:Ucone ID="Ucone1" runat="server" />
</div>
</form>
</body>
</html>
用户控件
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Ucone.ascx.cs" Inherits="UserControl_Ucone" %>
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
<asp:Button ID="btnAdd" runat="server" Text="Add" />
<input type="hidden" id="hid_html" name="hid_html" />
<div id="div_inner_input" runat="server">
</div>
用户控件后台：
public partial class UserControl_Ucone : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
this.btnAdd.Attributes.Add("onclick", "return getAllCode_IE();");
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
this.btnAdd.Click += new EventHandler(btnAdd_Click);
}
void btnAdd_Click(object sender, EventArgs e)
{
this.div_inner_input.InnerText = Request.Form["hid_html"].ToString();
}
}
