AjaxPro的应用

自己用AjaxPro做了一个简单登陆，应用AjaxPro需要在配置文件中做修改

在<system.web></system.web>标签对中添加如下代码

<httpHandlers>
<add verb="POST,GET" path="ajaxpro/*.ashx" type="AjaxPro.AjaxHandlerFactory, AjaxPro.2"/>
</httpHandlers>

配置文件修改后即可应用。再看以下登陆操作

HTML:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ajaxpro.aspx.cs" Inherits="Login_ajaxpro" %>

<!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>无标题页</title>
<script type="text/javascript">
function Login_ButtonClick(){
var username = document.getElementById("Text1").value;
var password = document.getElementById("Text2").value;
document.getElementById("loading").style.display="block";
Login_ajaxpro.UserName(username,password,CallBackServer);
}
function CallBackServer(res){
var success = res.value;
document.getElementById("loading").style.display="none";
if(success){
alert("登陆成功");
}
else{
alert("登陆失败,请检查您的用户名跟密码!");
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Text1" type="text" />
<input id="Text2" type="text" />
<input id="Button1" type="button" value="button" onclick="Login_ButtonClick();" />
<div id="loading" style="display:none;">正在登陆......</div>
</div>
</form>
</body>
</html>
