首先添加一个login.html 代码如下:
<title>$.Ajax()方法发送请求</title>
<script type="text/javascript" src="jquery-1.4.1.js"></script>
<style type="text/css">
body
{
font-size: 13px;
}
.divFrame
{
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;
150px;
margin-right: 3px;
}
.btn
{
border: #666 1px solid;
padding: 2px;
50px;
}
</style>
<script type="text/javascript">
$(function () {
$("#txtName").focus(); //输入焦点
$("#txtName").keydown(function (event) {
if (event.which == "13") {
$("#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
({
url: "Login.aspx", //请求登录处理页
dataType: "html",//登录处理页
//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>
添加login.aspx页面 代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="WebApplication3.Login" %>
<%
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);
%>
