javascript - DataTable中是否有停止显示 "No data available in table"的设置？

Question

最初我的表没有数据，我得到“表中没有可用数据”，这是预期的功能。

我不希望创建任何文本或行，因为我将根据用户操作通过 Ajax 填充表格。

是否有设置停止在表格中显示该行？我似乎找不到一个。此代码有效，但第一行显示“表中无可用数据”。这是 jQuery 代码:

$.ajax({
    type: 'GET',
    url: '/Home/postInformationofConferenceTitle',
    dataType: "JSON",
    success: function (data) {

        $.post("/Home/selectRooms", { xtitle: data.xglobalTitle }, function (data) {

            var ndx = 0;
            $.each(data.xroom_name, function (key, value) {

                var Xroom_name = data.xroom_name[ndx];
                var Xroom_plan = data.xroom_plan[ndx];

                var column =
                  ('<tr>' +
                    '<td>' +
                    '<div class="img-container">' +
                    '<img src="../../assets/img/room-plan/' + Xroom_plan + '" alt="..." id="imgsrc">' +
                    '</div>' +
                    '</td>' +
                    '<td id="imgname">' + Xroom_name + '</td>' +
                    '<td class="text-right">' +
                    '<a href="#" class="btn btn-simple btn-warning btn-icon edit" data-toggle="modal" data-target="#myModal"><i class="fa fa-edit"></i></a>' +
                    '<a href="#" class="btn btn-simple btn-danger btn-icon remove" ><i class="fa fa-times"></i></a>' +
                    '</td>' +
                    '</tr>');

                document.getElementById('colmn').innerHTML = document.getElementById('colmn').innerHTML + column;

                ndx++;

            });

        });

    }
})

我猜您可能正在查看数据表的语言设置。

language : {
        "zeroRecords": " "             
    },

(注意“”之间的空格。(这是一个 hack，但发现它现在很有用。)

$(document).ready(function () {

	var serverData = [
	]
	var table = $('#example').DataTable({
   language : {
            "zeroRecords": " "             
        },
		data: serverData,
		columns: [
			{ data: "name" },
			{ data: "age" },
			{ data: "isActive" },
			{ data: "friends" },
		],
		'columnDefs': [{
			'targets': 2,
			'render': function (data, type, full, meta) {
				let checked = ''
				if (data) {
					return '<input type="checkbox" checked / >';
				}
				else {
					return '<input type="checkbox"  / >';
				}
				return data;
			}
		},
		{
			'targets': 3,
			"render": function (data, type, full, meta) {
				var selectInitial = "<select>";
        var selectClosing = "</select>";
        var options = '';
				$.each(data, function (key, value) {
					options = options+"<option value="+value.id+">"+value.name+"</option>";
				});
				return selectInitial+options+selectClosing;
			}
		}
		],
	});

});
