首先，新建Login.html页面：
<!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>
<title>$.ajax()方法发送请求</title>
<script type="text/javascript" src="Scripts/jquery-1.4.1.js"></script>
<style type="text/css">
body
{
font-size: 13px;
}
.divFrame
{
width: 225px;
border: solid 1px #666;
}
.divFrame .divTitle
{
padding: 5px;
background-color: #eee;
height: 23px;
}
.divFrame .divTitle span
{
float: left;
padding: 2px;
padding-top: 5px;
}
.divFrame .divContent
{
padding: 8px;
text-align: center;
}
.divFrame .divContent .clsShow
{
font-size: 14px;
line-height: 2.0em;
}
.divFrame .divContent .clsShow .clsError
{
font-size: 13px;
border: solid 1px #cc3300;
padding: 2px;
display: none;
margin-bottom: 5px;
background-color: #ffe0a3;
}
.txt
{
border: #666 1px solid;
padding: 2px;
width: 150px;
margin-right: 3px;
}
.btn
{
border: #666 1px solid;
padding: 2px;
width: 50px;
}
</style>
<script type="text/javascript">
$(function () {
$("#txtName").focus();//输入焦点
$("#txtName").keydown(function (event) {
if (event.which == "13") {//回车键,移动光标到密码框
$("#txtPass").focus();
}
});
$("#txtPass").keydown(function (event) {
if (event.which == "13") {//回车键，用.ajax提交表单
$("#btnLogin").trigger("click");
}
});
$("#btnLogin").click(function () { //“登录”按钮单击事件
//获取用户名称
var strTxtName = encodeURI($("#txtName").val());
//获取输入密码
var strTxtPass = encodeURI($("#txtPass").val());
//开始发送数据
$.ajax
({ //请求登录处理页
url: "Login.aspx", //登录处理页
dataType: "html",
//传送请求数据
data: { txtName: strTxtName, txtPass: strTxtPass },
success: function (strValue) { //登录成功后返回的数据
//根据返回值进行状态显示
if (strValue == "True") {//注意是True,不是true
$(".clsShow").html("操作提示，登录成功！" + strValue);
}
else {
$("#divError").show().html("用户名或密码错误！" + strValue);
}
}
})
})
})
</script>
</head>
<body>
<form id="frmUserLogin">
<div class="divFrame">
<div class="divTitle">
<span>用户登录</span>
</div>
<div class="divContent">
<div class="clsShow">
<div id="divError" class="clsError">
</div>
<div>
名称：<input id="txtName" type="text" class="txt" /></div>
<div>
密码：<input id="txtPass" type="password" class="txt" /></div>
<div>
<input id="btnLogin" type="button" value="登录" class="btn" />  
<input id="btnReset" type="reset" value="取消" class="btn" />
</div>
</div>
</div>
</div>
</form>
</body>
</html>
然后，新建Login.aspx，接收并处理数据：
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="JSDemo.Login" ResponseEncoding="gb2312"%>
<%
string strName = System.Web.HttpUtility.UrlDecode(Request["txtName"]);
string strPass = System.Web.HttpUtility.UrlDecode(Request["txtPass"]);
bool login = false;
if (strName == "admin" && strPass == "admin")
{
login = true;
}
Response.Write(login);
%>
