前端
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="index1.aspx.cs" Inherits="index1" %>
<!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 id="Head1" runat="server">
<title>系统</title>
<link href="scripts/miniui/themes/default/miniui.css" rel="stylesheet" type="text/css" />
<script src="scripts/boot.js" type="text/javascript"></script>
<script src="scripts/jquery-1.6.2.min.js" type="text/javascript"></script>
<script src="scripts/miniui/miniui.js" type="text/javascript"></script>
</head>
<body>
<form id="form2" runat="server">
<div id="form1" >
<input value="Login" type="button" onclick="submitlogin1()" />
</div>
<script type="text/javascript">
function submitlogin1() {
$.ajax({
url: "exam7.aspx?method=jumptomain",
data: { },
type: "post",
success: function (text) {
alert(text);
--此处TEXT没有值--
},
error: function (jqXHR, textStatus, errorThrown) {
alert(jqXHR.responseText);
}
});
}
</script>
</form>
</body>
</html>
后台：
public partial class exam7 : System.Web.UI.Page
{
public void jumptomain()
{
Response.Write("dasfasfasdfasdf");
}
}

同样的例子，别人的却能实现返回值，不明白，别人的代码！
后台：
public void LoadFiles()
{
String folderId = Request["folderId"];
String sql = "select * from plus_file where pid = " + folderId + " and folder = 0 order by updatedate";
ArrayList files = new DBUtil().Select(sql);
String json = JSON.Encode(files);
Response.Write(json);
}
前端
function showFiles(folderId) {
//var messageid = mini.loading("Loading, Please wait ...", "Loading");
$.ajax({
url: "../data/FileService.aspx?method=LoadFiles&folderId=" + folderId,
success: function (text) {
var files = mini.decode(text);
refreshFiles(files);
}
});
}
请问应该怎么修改？
