Post表单如何保存页面状态并输出源码
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(); }}推荐博客：RyanDoc数据字典 For SqlServer版 RyanCoder代码生成器 For SqlServer版
