javascript - 如何限制jquery数据表字段在MVC View 中显示所有列

Question

我在此链接中使用 jquery DataTable 在 MVC 中创建一个网格来显示一些数据并显示和隐藏该列。

https://datatables.net/examples/api/show_hide.html

我显示所有列，然后根据用户选择的列显示和隐藏。但我喜欢在网格的开头仅显示 5 列，而不是所有列，并且用户能够显示/隐藏其余列。

我不知道该怎么做。

这是我的代码:

这是显示/隐藏列的 jquery 代码:

   $(document).ready(function () {

        var table = $('#DataLegal').DataTable({
          "paging": true
        });
        $('a.toggle-vis').on('click', function (e) {
                       event.preventDefault ? event.preventDefault() : event.returnValue = false;

            //Get the column API object
            var column = table.column($(this).attr('data-column'));

            // Toggle the visibility
            column.visible(!column.visible());

        });

        var ms = $('#magicsuggest').magicSuggest({
            // Converts our C# object in a JSON string.
            data: @Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(columns))
        });

        $(ms).on('selectionchange', function(e,m){

            // Turn on ALL columns... Like a reset...
            $.each(table.columns()[0], function(index) {
                table.column(index).visible(true);
            });

            // Turn off each column in the value array... Value = int[0, 1, 2, ...]
            $.each(this.getValue(), function(index, item) {
                table.column(item).visible(false);
            });


        });

    });

这是我的网格，显示了所有列。我喜欢限制它首先仅显示 5 列:

 //This is when user sees the column name to show/hide
 <div id="content">

    <table>
        <tr>

        <td>
             <div id="magicsuggest"></div>


        </td>
        <td id="returnS5"></td>
    </tr>

    </table>
    </div>

 //This is the grid that I have all the column and I like to limit it to 5 column
<br />
 <table width="100%" class="display" id="DataLegal" cellspacing="0">
    <thead>
        <tr>
            <th>Entity</th>how hide some column

Answer 1

列的初始可见性是一个初始化选项，可以在 columnDefs 属性中设置。示例:

    "columnDefs": [
        {
            "targets": [ 2 ],
            "visible": false,
            "searchable": false
        }]
