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

复制代码代码如下:

 
<%@ 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：

复制代码代码如下:

 
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(); 
} 
}
