Post表单如何保存页面状态并输出源码

来源：互联网发布：淘宝宝贝失效编辑：程序博客网时间：2024/06/08 11:16

思路：先执行脚本,复制源码到隐藏域里,再输出源码，注意代码设置ValidateRequest="false"

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", "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();    }}
