aspx代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> <script src="Scripts/jquery.min.js"></script> </head> <body> <form id="form1" runat="server"> <div> <input id="txtcode" type="text" /> <input id="btn" type="button" value="检查" /> <div id="name"></div> <div id="sex"></div> <div id="birthday"></div> <div id="nation"></div> </div> </form> <script type="text/javascript"> $(document).ready(function (e) { $("#btn").click(function (e) { var code = $("#txtcode").val(); //调AJAX $.ajax({ url: "Show.ashx",//处理页面 type: "POST",//数据提交的方式,共两种POST,GET data: { code : code },//要传输的数据,JSON格式 datatype:"XML",//返回的数据格式,共三种TEXT,JSON,XML success: function (data) { //回调函数 $("#name").text($(data).find("Name").eq(0).text());//不在同一级,有两个Name时,想取哪一个用eq来控制 $("#sex").text($(data).find("Sex").text()); $("#nation").text($(data).find("Nation").text()); $("#birthday").text($(data).find("Birthday").text()); } }) }) }) </script> </body> </html>
新建处理页面时,最好不用新建窗体,而是添加→添加新项→一般处理程序,后缀名是.ashx
