DataTables 如何用超链接填充列？

Question

我正在使用 DataTables server-side 处理并想在某些 table 的第一个单元格中添加一个超链接。

我可以添加一列并使 table 正确呈现，但我不知道如何获得单元格中的超链接。

我不想在每个 table 中都使用这个，现在它只适用于其中两个，但这可能会发生变化。

我对所有 table 使用相同的初始化，但所有 table 都没有相同的列。可能有 3 到 65 列，具体取决于我正在渲染的 table，所以我不能只将列添加到初始化中。这是我现在的初始化方式：

$(document).ready(function ()
{
    // Setup - add a text input to each footer cell
    $('#DataTable tfoot th').each(function ()
    {
        var title = $(this).text();
        $(this).html('<input type="text" placeholder="Search ' + title + '" />');
    });

    var table = $('#DataTable').DataTable({
        "lengthMenu": [[25, 50, 75, 100, 150, -1], [25, 50, 75, 100, 150, 'All']],
        "dom": '<"top"Bifpl<"clear">>rt<"bottom"ip<"clear">>',
        "buttons": [{
            extend: 'collection',
            text: 'Selection',
            buttons: ['selectAll', 'selectNone']
        }, {
            extend: 'collection',
            text: 'Export',
            buttons: ['export', 'excel', 'csv', 'pdf', { extend: 'excel',
                text: 'Export Current Page',
                exportOptions: {
                    modifier: {
                        page: 'current'
                    }
                },
                customize: function (xlsx)
                {
                    var sheet = xlsx.xl.worksheets['sheet1.xml'];
                    $('row:first c', sheet).attr('s', '7');
                }
            },

            {
                text: 'Export All to Excel',
                action: function (e, dt, button, config)
                {
                    dt.one('preXhr', function (e, s, data)
                    {
                        data.length = -1;
                    }).one('draw', function (e, settings, json, xhr)
                    {
                        var excelButtonConfig = $.fn.DataTable.ext.buttons.excelHtml5;
                        var addOptions = { exportOptions: { 'columns': ':all'} };

                        $.extend(true, excelButtonConfig, addOptions);
                        excelButtonConfig.action(e, dt, button, excelButtonConfig);
                    }).draw();
                }
            }]
        }
        ],
        "fixedHeader": {
            header: true,
            footer: true
        },
        "select": true,
        "processing": true,
        "serverSide": true,
        "ajax": {
            "url": "./ServerSide.php",
            "type": "POST"
        },
//Added this to the initialization
        columnDefs: [
        {
            targets: 0,
            render: function (data, type, row, meta)
            {
                if (type === 'display')
                {
                    data = '<a href="FormToEdit.php?everything=' + encodeURIComponent(row) + '">' + data + '</a>';
                }
                return data;
            }
        }],
//It adds the hyperlink to all tables and not just the ones that I want
        initComplete: function ()
        {
            var api = this.api();

            // Apply the search
            api.columns().every(function ()
            {
                var that = this;

                $('input', this.footer()).on('keyup change', function ()
                {
                    if (that.search() !== this.value)
                    {
                        that
                          .search(this.value)
                          .draw();
                    }
                });
            });
        }
    });
});

以下是我创建 tables 的方法：

<?php
    $hsql = "select Headings from TableHeadings where TableName = '$TableName' order by Id";

    $getHeadings = $conn->query($hsql);
    $rHeadings = $getHeadings->fetchALL(PDO::FETCH_ASSOC);
    $CountHeadings = count($rHeadings);
    $tsqlHeadings = '';
    for ($row = 0; $row < $CountHeadings; $row++)
    {
        $headings[$row] = $rHeadings[$row]["Headings"];
    }
?>
<table id="DataTable" class="display nowrap" style="width: 100%; border: 1px">
    <thead>
        <tr>
            <?php
            foreach($headings as $heading)
            {?>
            <th class="cell"><?php echo $heading; ?></th><?php
            }?>
        </tr>
    </thead>
    <tfoot>
        <tr>
            <?php
            foreach($headings as $heading)
            {?>
            <th class="cell"><?php echo $heading; ?></th><?php
            }?>
        </tr>
    </tfoot>
</table>

编辑

我已经用我添加的内容编辑了上面的初始化脚本。现在的问题是它将此超链接添加到所有 table，而不仅仅是具有 Edit 列的超链接。如果第一列 header 是 Edit?

，我将如何进一步修改以仅在 table 上获取它

Answer 1

我决定以不同的方式解决这个问题。

将editable的table赋予不同的ID，然后用上面的代码初始化。其余部分将在第一列中没有创建超链接的部分进行初始化。所以现在我有了这个来创建我的 tables:

<table id="<?php if($Edit == 1){echo "DataTableEdit";}elseif($Edit == 0){echo "DataTable";}?>" class="display nowrap" style="width: 100%; border: 1px">

因此，如果他们有 $Edit = 1，他们将获得不同的初始化。新脚本现在看起来像这样：

<script type="text/javascript" class="init">
    $.fn.dataTable.ext.buttons.export =
    {
        className: 'buttons-alert',
        "text": "Export All Test",
        action: function (e, dt, node, config)
        {
            alert('Export All Test');
        }
    };

    $(document).ready(function ()
    {
        // Setup - add a text input to each footer cell
        $('#DataTableEdit tfoot th').each(function ()
        {
            var title = $(this).text();
            $(this).html('<input type="text" placeholder="Search ' + title + '" />');
        });

        var table = $('#DataTableEdit').DataTable({
            "lengthMenu": [[25, 50, 75, 100, 150, -1], [25, 50, 75, 100, 150, 'All']],
            "dom": '<"top"Bifpl<"clear">>rt<"bottom"ip<"clear">>',
            "buttons": [{
                extend: 'collection',

            }, {
                extend: 'collection',

这允许我拥有 table 的 editable 和 table 不是的。我可以将 $Edit 添加到任何需要编辑的 table 中。
