我有一个 JavaScript 数据表。下面列出了加载的 JS 库，完全按照该顺序。
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.19/js/jquery.dataTables.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/1.5.2/js/dataTables.buttons.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/1.5.2/js/buttons.flash.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.3/jszip.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.36/pdfmake.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.36/vfs_fonts.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/1.5.2/js/buttons.html5.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/1.5.2/js/buttons.print.min.js"></script>
数据表的创建如下:
myTable = $('#example').on('error.dt', function (e, settings, techNote, message) {
console.log('An error has been reported by DataTables: ', message);
}).DataTable({
dom: 'lBfrtip',
buttons: ['copyHtml5', 'excelHtml5', 'pdfHtml5', 'csvHtml5'
],
fixedColumns: true,
"columnDefs": [{
//"bSortable": false,
"width": '60%',
"defaultContent": "-",
"targets": "_all"
}]
});
问题是，我在浏览器上看不到导出按钮。我正在使用谷歌浏览器。在类似的问题中，人们说 JS 库的顺序很重要，但我的顺序与他们的一致。在站点设置中，还允许使用 Flash。当我按F12时，Chrome控制台没有错误。我找不到为什么按钮没有显示在屏幕上。尝试在设置按钮时不使用 Html5，但没有成功。任何帮助将不胜感激。
最佳答案
您可能已经完成了此操作，但只是为了检查...您是否还加载了按钮的 CSS？
<link href="https://cdn.datatables.net/buttons/1.5.1/css/buttons.dataTables.min.css" rel="stylesheet">
这个基于您的代码的示例对我有用。
