jQuery Datatables按钮显示为链接..而不是按钮

Question

使用jQuery DataTables 1.10.15，我正在尝试使用文件导出选项。

以下是我在页面上加载脚本的方式：

<script src="/Scripts/DataTables/jquery.dataTables.js"></script>
<script src="/Scripts/DataTables/dataTables.bootstrap.js"></script>
<script src="/Scripts/DataTables/dataTables.buttons.min.js"></script>
<script src="https://cdn.datatables.net/buttons/1.3.1/js/buttons.flash.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.3/jszip.min.js"></script>
<script src="https://cdn.rawgit.com/bpampuch/pdfmake/0.1.27/build/pdfmake.min.js"></script>
<script src="https://cdn.rawgit.com/bpampuch/pdfmake/0.1.27/build/vfs_fonts.js"></script>
<script src="https://cdn.datatables.net/buttons/1.3.1/js/buttons.html5.min.js"></script>
<script src="https://cdn.datatables.net/buttons/1.3.1/js/buttons.print.min.js"></script>

这是我的DataTable设置：

var table = $('#NewTable').DataTable({
    dom: 'Bfrtip',
    buttons: [ 'excel', 'pdf' ],
    'aoColumnDefs': [
        { "bSortable": false, "aTargets": [2, 7] },
        { "bSearchable": false, "aTargets": [7] }
    ]
});

以下是它们的显示方式：

如何让它们显示为按钮而非链接？

Answer 1

你很可能错过了正确的css文件。

尝试将此css链接（从CDN）添加到标题中。

https://cdn.datatables.net/buttons/1.3.1/css/buttons.dataTables.min.css

工作示例：

var table = $('#NewTable').DataTable({
    dom: 'Bfrtip',
    buttons: [ 'excel', 'pdf' ],
    'aoColumnDefs': [
        { "bSortable": false, "aTargets": [2, 7] },
        { "bSearchable": false, "aTargets": [7] }
    ]
});
