Question

我正在使用这些cdn

 <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/buttons/1.2.2/css/buttons.dataTables.min.css">

代码如下：

 $('#tblId').DataTable({
                    dom: 'Bfrtip',

                    buttons: [
                      {
                          extend: 'collection',
                          text: 'Export',
                          buttons: ['pdfHtml5', 'csvHtml5', 'copyHtml5', 'excelHtml5']
                      }
                    ]
                });

当我执行此代码段时，按钮未显示

Answer 1

您的代码存在问题，这是扩展和添加自定义文本的正确语法

buttons: [
    {
    extend: 'copyHtml5',
    text: "copy to clipboard"
  },
  {
    extend: 'excelHtml5',
    text: 'Save as excel sheet'
  },
  'csvHtml5',
  'pdfHtml5'
]
