AJAX基于ASP.NET MVC
看一下Controller中的对应的Action方法：
1 public void SearchUserAjax()
2 {
3 string uerid = Request["name"];
4
5 List＜UserLunchList＞ lunchs = (
6 from userlunch in repository.UserLunchLists.ToList()
7 where userlunch.UserID == int.Parse(uerid)
8 select userlunch
9 ).ToList();
10 StringBuilder sb = new StringBuilder();
11 sb.Append("＜table id='LunchList' style='display:none'＞＜tr＞＜th＞User＜/th＞＜th＞Time＜/th＞＜th＞Price＜/th＞＜/tr＞");
12 foreach (UserLunchList lunch in lunchs)
13 {
14 sb.Append("＜tr＞＜td＞" + lunch.User.UserName + "＜/td＞＜td＞" + lunch.Time.ToShortDateString() + "＜/td＞＜td＞" + lunch.Cost + "＜/td＞＜/tr＞");
15 }
16 sb.Append("＜/table＞");
17 Response.ContentType = "text/html";
18 Response.Write(sb.ToString());
19 }
说穿了很简单，就是把想要的数据直接写到Response中就可以了，这里为了方便起见，就是写好了Table的格式。有一个地方需要注意的就是这个语句
Response.ContentType = "text/html" 很重要，它告知JavaScript以何种格式来处理Response中的数据。
核心内容就这么简单，呵呵。
如果觉得写JavaScript代码烦的话，可以使用extension方法，自定一个Html.Form或者其它的控件。
