MVC3，AJAX如何获取和遍历集合啊，已经第4次问了...哪位大神帮帮忙
这个是我的代码
$.ajax({
type: 'Post',
url: '@Url.Action("GetJSON", "Article")',
dataType: "json",
success: function (data) {
alert(data.length);---长度总是为1
$.each(data, function (i, item) {
alert(item.CatalogId);
});
}
});
上面有问题么？
还是这里的问题

[HttpPost]
public JsonResult GetJSON()
{
return Json(new Catalog().GetPathItems());
}



public class Catalog{
//属性省略
public List<Catalog> GetPathItems(){
List<Catalog> list=new List<Catelog>();
Catelog c1=new Catalog{name="a",CatalogId=2,....};
list.Add(c1);
.
.
.
Catelog c30=new Catalog{name="a",CatalogId=2,....};
list.Add(c30);
return list;
}
}


怎么样才能把添加进去的对象，全部打印出来？

Control方法

C# code

[HttpPost]        public JsonResult GetJSON()        {            return Json(new Catalog().GetPathItems());        }        public class Catalog        {            //属性省略            public int CatalogId { get; set; }            public string name { get; set; }            public List<Catalog> GetPathItems()            {                List<Catalog> list = new List<Catalog>();                Catalog c1 = new Catalog { name = "a", CatalogId = 2 };                list.Add(c1);                Catalog c2 = new Catalog { name = "a", CatalogId = 2 };                list.Add(c2);                return list;            }        }
