];
$.post(“Home/Test”, { users: String.toSerialize(data) }, function(text) {
alert(String.toSerialize(text));
}, “json”);
});
});

点击按钮提交数据,监控浏览器,可以发现提交的数据是json对象的序列化后的内容:

其次,后台服务器处理参数绑定:

using System.Web.Mvc;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
namespace WebOS.Controllers

[HandleError]
public class HomeController : Controller

/// <returns>提交的用户数组</returns>
public ActionResult Test([ModelBinder(typeof(JsonBinder<User>))]List<User> users)
{
return Json(users, JsonRequestBehavior.AllowGet);
}
}
/// <summary>

public class User
{
