jquery获取表单值的利器：serialize()
前台：[切记：每个表单元素， 都应该带有name， 否则是取不到的。]
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %> <!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></title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> function test() { $("#Action").val(1); var vals = $("#tableForm :input").serialize(); //var vals = $("#form1").serialize();//两种都可以，但后一种会多取__ViewState这个系统hidden $.post("Default3.aspx", vals, function (data) { alert("前台取得值：\n" + vals+"\n后台取得值：\n"+data); }); } </script> </head> <body> <form id="form1" runat="server"> <table id="tableForm" style="border-collapse:collapse;" cellpadding="5" cellspacing="2" border="1"> <tr><td>姓名:</td><td><input id="Name" name="Name" type="text" value="刘 军" /><input id="Action" name="Action" type="hidden" value="0" /></td></tr> <tr><td>密码:</td><td><input id="Pwd" name="Pwd" type="password" value="123456" /></td></tr> <tr><td>性别:</td><td> <input name="Gender" type="radio" checked="checked" value="Male" />男 <input name="Gender" type="radio" value="Female" />女</td> </tr> <tr><td>爱好：</td><td> <input id="Checkbox1" type="checkbox" checked="checked" name="Hobby" value="1" />足球 <input id="Checkbox2" type="checkbox" checked="checked" name="Hobby" value="2" />象棋</td> </tr> <tr><td>留言：</td><td><textarea id="Note" name="Note" cols="20" rows="2">+ |</textarea></td></tr> <tr><td>籍贯：</td><td> <select id="Select1" name="Home" > <option value="">---请选择---</option> <option value="湖南" selected="selected">湖南</option> <option value="湖北">湖北</option> </select></td> </tr> <tr><td colspan="2"><input id="Button1" type="button" value="测试" οnclick="test()" /></td></tr> </table> </form> </body> </html>后台：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Text; public partial class Default3 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Request.Form["Action"] == "1") { Ajax(); } } private void Ajax() { StringBuilder sb = new StringBuilder(); foreach (string s in Request.Form.AllKeys) { sb.AppendFormat("{0}: {1}\n",s,Request.Form[s] ); } Response.Write(sb.ToString()); Response.End(); } }—————————————— 结果 —————————————
