2.Controller里面的代码
namespace NHibernateSample.Mvc2Web.Controllers
{
public class AjaxController : Controller
{
//
// GET: /Ajax/
public ActionResult Index()
{
return View();
}
public ActionResult Content()
{
return Content("[\"Name\",18,\"ture\"]", "text/json");//json内容必须是数组，js 函数eval 转化为json数据。
}
class ListItem
{
public string Value{get;set;}
public string Text{get;set;}
}
public ActionResult Json()
{
//List<ListItem> list = new List<ListItem>() {
//new ListItem() { Value = "1", Text = "VA" }
//};
//return this.Json(list, JsonRequestBehavior.AllowGet);
var json = new { name = "nie.jl", age = 13 };//true 布尔型 好想不行，直接变成字符串。
return Json(json,JsonRequestBehavior.AllowGet);
}
}
}
