jquery - 如何将此 js 数组传递到我的 MVC 3 Controller ？

Question

我在 Controller 中得到空值。不确定我错过了什么。

我有一个网格，其中有一个客人列表(带有姓名和电子邮件)，用户可以通过复选框选择客人。

然后我读取所选联系人的姓名和电子邮件并构建 js 数组。然后这个数组被传递到 MVC 3 Controller 。

JS代码:

var name ='', email='';
    var guest = new Array();
            var guests = new Array();
            $('.CBC').each(function () {  //loop grid by checkbox class
                if (this.checked) {
                    name = GetSelectedName();
                    email = GetSelectedEmail();
                    guest = { 'Email': email, 'Name': name };
                    guests.push(guest);
                }
            });

        $.ajax({
        type: "POST",
        url: GetURL(),
        data: guests,
        dataType: "json",
        success: function (res) {
           //do something
        }
});

Controller :

[HttpPost]
    public ActionResult AddGuests(List<SelectedGuest> guests)
    {            
        GuestService svc = new GuestService();
        //do something with guests
        //But Name and Email of all items in guests are null!!!
    }

public class SelectedGuest
{
    //represent the email columns of the contact grid
    public string Email { get; set; }

    //represent the Name column of the contact grid
    public string Name { get; set; }
}

我需要显式地将js数组转换为json对象来序列化它吗？

Answer 1

$.ajax({
            type: "POST",
            url: "yourUrl",
            data: JSON.stringify(yourArray),
            contentType: "application/json; charset=utf-8"
        });

contentType: "application/json; charset=utf-8"- 非常重要的部分

[HttpPost]
public void Fake(List<yourType> yourArray)
{
}
