Question

即使表中有记录，我的带有 ajax 源的数据表也会显示在 language.infoEmpty 中声明的消息。

类中创建数据表的函数：

createTable() {
const self = this;
let table = $('#' + this.getClassName()).DataTable({
    "processing": true,
    "serverSide": true,
    "ajax": {
        "url": this.getUrl() + this.getClassName() + "/ajax-paging",
        "type": "POST"
    },
    "columnDefs": [
        {
            "name": 'id',
            "targets": [0],
            "visible": false,
            "searchable": false,
        },
        {
            "name": 'Aktiv',
            "targets": [2],
            "render": function (data, type, row) {
                if (type === 'display') {
                    let checkedvalue = '';
                    if (data) {
                        checkedvalue = 'checked="checked"';
                    }
                    return '<input style="margin-left: auto; margin-right: auto;" type="checkbox" class="form-control form-control_table" ' + checkedvalue + ' disabled>';
                }
                return data;
            },
            "searchable": false,

        },
        {
            "targets": [3],
            "render": function (data, type, row) {
                if (type === 'display') {
                    let ret = '<div style="float:right;" aria-label="benutzer actions"><img src="' + self.getUrl() + 'img/bootstrap-icons/search.svg" />';
                    return ret + '</div>';
                }
                return data;
            },
            "searchable": false,
        }
    ],
    "columns": [
        { data: self.idColName, name: "ID" },
        { data: ProjektKonstanten.COL_LOGINNAME, name: "Loginname" },
        { data: ProjektKonstanten.COL_AKTIV, name: "Aktiv" },
        { "orderable": false, data: self.idColName },
    ],
    "order": [1, 'asc'],
    "language": {
        "lengthMenu": '_MENU_ records per page'),
        "zeroRecords": 'No match',
        "info": 'Page _PAGE_ of _PAGES_',
        "infoEmpty": 'No user found',
        "infoFiltered": '(filtered from _MAX_ records)',
        "search": 'Search:',
        "paginate": {
            "first": "<img src='" + images.first + "'/>",
            "last": "<img src='" + images.last + "'/>",
            "next": "<img src='" + images.next + "'/>",
            "previous": "<img src='" + images.back + "'/>",
        }
    }
});
return $table;

}

欢迎提出任何建议/想法？

（我不知道还有什么要解释的。但是 Stacktrace 告诉我写的代码比解释的多，所以我在这里写这段文字是为了 Stacktrace 让我做这个帖子；））

检查JSON响应后，我看到maxRowCount和recordFiltered参数为0。在他们得到正确的号码后，它起作用了。

数据表，即使有记录也会显示“infoEmpty”消息
