一、AjaxJson.aspx
处理业务数据，产生JSon数据，供JqueryRequest.aspx调用，代码如下:
protected void Page_Load(object sender, EventArgs e)
{
string u = Request["UserName"];
string p = Request["Password"];
string output = string.Format("'UserName':'{0}','Password':'{1}'", u, p);
Response.Write("[{");
Response.Write(output);
Response.Write("}]");
Response.End();
} 二、JqueryRequest.aspx
通过点击按钮来请求AjaxJson.aspx，获取JSon数据。代码如下：
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript" language="javascript" src="js/jquery-1.3.2.js"></script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="text" name="Text1" id="Text1"/><br />
<input type="text" name="Text2" id="Text2"/>
<br />
<input type="button" id="btn1" onclick="BtnClick()" />
</div>
<div id="dd">
sd
</div>
<div>
<script type="text/javascript" language="javascript">
function BtnClick() {
var uid = $("#Text1").val();
var pwd = $("#Text2").val();
$.ajax({
url: "AjaxJson.aspx",
type: "POST",
data: { UserName: uid, Password: pwd },
success: function(data) {
var json = eval(data); //eval("(" + data + ")");
$.each(json, function(idx, item) {
var user = item.UserName;
var pass = item.Password;
$("#dd").html("<h1>用户名：" + user + " 密码：" + pass + "</h1>");
});
}
});
}
</script>
</div>
</form>
</body>
