Question

我正在使用带有剃须刀页面的.net核心，并且我有一个模型作为对象列表，如下所示：

public class Member
{
    public List<User> member { get; set; }
}

public class User
{
    public String fname { get; set; }
    public String lname { get; set; }
}

并且我有一个表单来填充对象，如下所示：

<form asp-controller="Population" asp-action="AddMember" method="post" class="form-horizontal" role="form" style="font-family:Cairo-Bold">
<div class="new-help add-form-container">
    <input asp-for="member.LastName" type="text" />
    <input asp-for="member.Firstname" type="text" />
</div>

，当用户单击按钮时，用户可以动态地从页面添加对象。我为他复制的按钮div如下所示：

<div class="row">
   <div class="col-lg-12">
    <a class="clone-button"><u> Add another</u></a>
   </div>
</div>

   $(function () {
        $(".clone-button").on('click', function () {
            var ele = $(this).closest('.new-help').clone(true);
            $(this).closest('.new-help').after(ele);
        });
    });

我如何绑定表格中的文本字段，以便将提交时添加的成员列表返回给控制器？

Answer 1

您应使用以下代码生成具有索引号的元素：

$(function () {

   $("#add").click(function (e) {
       e.preventDefault();
       var i = $(".items").length;
       var n = '<input type="text" class="items" name="ListItems[' + i + '].Name" />';
       $("#item-list").append(n);
   });

});

Answer 2

我发现模型中的List字段必须以大写字母开头，否则我无法获得正确的模型绑定。

void DispatchNotificationThatServiceIsRunning()
        {
            _notificationIsLive = true;

            RemoteViews contentView = new RemoteViews(PackageName, Resource.Layout.Notification);
            contentView.SetTextViewText(Resource.Id.txt_crrentSong_notification, Activity_Player.txt_CurrentSong.Text);
            contentView.SetTextViewText(Resource.Id.txt_crrentSong__artist_notification, Activity_Player.txt_CurrentArtist.Text);

            notificationBuilder = new Notification.Builder(this);

            Task.Delay(_countDownFirstRound).ContinueWith(t =>
            {
                notificationBuilder
                .SetSmallIcon(Resource.Drawable.btn_icon_header)
                .SetCustomContentView(contentView);

                var notificationManager = (NotificationManager)GetSystemService(NotificationService);
                notificationManager.Notify(50, notificationBuilder.Build());

                DispatchNotificationThatServiceIsRunning();//This is for repeate every 1s.

                _countDownFirstRound = 50;

                // Click on notification, and return to app. Only works, because _2TimerRunning is set as : "LaunchMode = LaunchMode.SingleInstance"
                Intent notificationIntent = new Intent(this, typeof(Activity_Player));
                notificationIntent.SetAction(Intent.ActionMain);
                notificationIntent.AddCategory(Intent.CategoryLauncher);
                PendingIntent contentIntent = PendingIntent.GetActivity(this, 1, notificationIntent, PendingIntentFlags.UpdateCurrent);
                notificationBuilder.SetContentIntent(contentIntent);

            }, 

            TaskScheduler.FromCurrentSynchronizationContext());
        }

    }

创建视图

public class Member
{
    public int MemberId { get; set; }
    public List<User> Users { get; set; }

}

控制器：

@model AddMember.Models.Member


<form asp-action="Create" method="post">

<div class="form-group" id="item-list">
    <a href="#" id="add">Add</a>
    <br/>
    <input type="text" asp-for="Users" class="items" name="Users[0].fname"/>
    <input type="text" asp-for="Users" class="items" name="Users[0].lname" />
</div>
<input type="submit" value="Create" class="btn btn-default" />
</form>
@section Scripts {
<script>
    $(function () {

       $("#add").click(function (e) {
           e.preventDefault();
           var i = ($(".items").length) / 2;
           var n = '<input type="text" class="items" name="Users[' + i + '].fname" />' +
               '<input type="text" class="items" name="Users[' + i + '].lname" />'

           $("#item-list").append(n);
       });

    });
</script>
}
