javascript - 親ノードの子がKendo TreeViewでチェックされているかどうかを確認するにはどうすればよいですか?

Question

これは機能的なスタートですが、最後の部分を取得できません...

debugger;
    var notificationId,
        treeView = $('#treeview').data("kendoTreeView");

    for (var i = 0; i < treeView.dataSource.view().length; i++)
    {
        if (treeView.dataSource.view()[i].checked)
        {
            if (treeView.dataSource.view()[i].hasChildren)
            {
                //this check is not working
                if (treeView.dataSource.view()[i].children.view()[i].checked)
                {
                    for (var j = 0; j < treeView.dataSource._data[i].notifications.length; j++)
                    {
                        notificationId = treeView.dataSource._data[i].notifications[j].ID;
                        alert('parent notification id: ' + notificationId);
                    }
                }

            }

誰かが私にこれを手伝ってもらえますか？

私はそれを行う方法を考え出しました：

$('#btnDelete').on('click', function()
{
    var treeView = $("#treeview").data("kendoTreeView");
    var userId = $('#user_id').val();

    $('#treeview').find('input:checkbox:checked').each(function()
    {
        debugger;
        var li = $(this).closest(".k-item")[0];
        var notificationId = treeView.dataSource.getByUid(li.getAttribute('data-uid')).ID;

        if (notificationId == "undefined")
        {
            alert('No ID was found for one or more notifications selected. These notifications will not be deleted. Please contact IT about this issue.');
        }
        else
        {
            $.ajax(
                {
                    url: '../api/notifications/deleteNotification?userId=' + userId + '&notificationId=' + notificationId,
                    type: 'DELETE',
                    success: function()
                    {
                        alert('Delete successful.');
                        CreateNotificationTree(userId);
                    },
                    failure: function()
                    {
                        alert('Delete failed.');
                    }
                });
            treeView.remove($(this).closest('.k-item'));
        }
    });
});
