会ajax的飘过

看论坛里好多人在找后台获取js表格的数据，就把以前的方法放在这里了

前台：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><!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>asp.net获取前台js表格的数据</title> <style type="text/css"> </style></head><body> <form id="form1" runat="server"> <h3>使用客户端添加表格的保存</h3> <p> 主是就是在提交到服务器之前，处理好表格里的信息，然后赋值给hidden<br /> to mqtheone:这里我设置最后一列只能输入数字了，你可以参考一下 </p> <div> <table id="tab1"> <tr> <th>名称</th> <th>内容</th> <th>值</th> <th></th> </tr> <tr> <td><input type="text" /></td> <td><input type="text" /></td> <td><input type="text" class="dis-ime" onkeypress="return check(event)"/></td> </tr> </table> <input type="button" style="margin-left:400px" mce_style="margin-left:400px" value="添加信息" id="btnAddInfo" /><br /> <asp:Button ID="Button1" runat="server" Text="提交" OnClientClick="initData();" onclick="Button1_Click" /> <asp:HiddenField ID="HiddenField1" runat="server" /> </div> </form></body><script type="text/javascript"></script></html>

后台获取：

using System;using System.Configuration;using System.Data;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Xml.Linq;public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { if (HiddenField1.Value != "") { string[] datas = HiddenField1.Value.Split('`'); int i = 0; System.Collections.Hashtable tb = new System.Collections.Hashtable(); DataTable dt = new DataTable();//取出数据放进DataTable dt.Columns.Add("Name", typeof(string)); dt.Columns.Add("Content", typeof(string)); dt.Columns.Add("Value", typeof(int)); while (i < datas.Length) { string str1=datas[i];//这样就取出数据了 string str2 = datas[i + 1]; string str3 = datas[i + 2]; int v = 0; int.TryParse(str3, out v); DataRow dr = dt.NewRow(); dr["Name"] = str1; dr["Content"] = str2; dr["Value"] = v; dt.Rows.Add(dr); i += 3; } Response.Write("数据行数为"+dt.Rows.Count); } }}
