科尔维斯jQuery列可见性不起作用

Question

请帮我解决问题，js colvis在我的项目中不起作用。 这是来源：

<script type="text/javascript">

    var table;

$(document).ready(function() {

        //datatables
        table = $('#table').DataTable({

            "processing": true, //Feature control the processing indicator.
            "serverSide": true, //Feature control DataTables' server-side processing mode.
            "order": [], //Initial no order.
            // Load data for the table's content from an Ajax source
            "ajax": {
                "url": "<?php echo site_url('customer/ajax_list')?>",
                "type": "POST",
                "data": function (data) {
                    data.salesnama = $('#salesnama').val();
                    data.type = $('#type').val();
                }
            },

            //Set column definition initialisation properties.
            "columnDefs": [
                {
                    "targets": [0], //first column / numbering column
                    "orderable": false, //set not orderable
                },
            ],

        });

    var colvis = new $.fn.dataTable.ColVis(table); //initial colvis
    $('#colvis').html(colvis.button()); //add colvis button to div with id="colvis"

});
</script>

问题是按钮colvis没有显示，我认为这段代码与datatable源中的示例相同

此代码查看按钮colvis

        <div class="col-sm-12">
            <div id="colvis"> tes</div>
        </div>  

Answer 1

我看不到您包含了buttons和dom选项， colvis应当包含这些buttons和dom选项，将其添加到当前脚本中：

  dom: 'Bfrtip',
    buttons: [
        'colvis'
    ]

记住要包括它的需求库。 这是官方页面上的一个非常基本的示例：

 $(document).ready(function() { $('#example').DataTable({ dom: 'Bfrtip', buttons: [ 'colvis' ] }); });
