打印预览在jQuery数据表中不显示任何数据

Question

我正在实现Copy、Excel、PDF和Print。前三个工作没有问题，但Print给我带来了问题。尝试打印时，如果单击"打印"按钮，则会打开打印预览页，但打印预览页上不会显示任何数据。打印预览仅显示标题。这是我的密码。

$("#task_table_list").DataTable({
dom: "fBrt",
buttons: [
{
extend: 'copy',
text: '<i class=" icon-file-openoffice position-left"></i>',
"className": 'all_button'
},{
extend:'pdf',
text:'<i class="icon-file-pdf position-left"></i>',
"className": 'all_button'
},
{
extend:'csv',
text:'<i class="icon-file-excel position-left"></i>',
"className": 'all_button'
},
{
extend:'print',
text:'<i class="icon-printer position-left"></i>',
"className": 'all_button',
// "autoPrint": false,
exportOptions: {
stripHtml: true
},
exportOptions: {
modifier: {
page: 'current'
}
},
},
]
})

Answer 1

下面是一个使用相同按钮的工作示例。

之前，这里有一些需要考虑的事项：

1. 确保样式表/脚本的顺序正确

<link rel="stylesheet" href="https://cdn.datatables.net/1.11.5/css/jquery.dataTables.min.css">
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/buttons/2.2.2/css/buttons.dataTables.min.css"/>
<script src="https://code.jquery.com/jquery-3.5.1.js"></script>
<script src="https://cdn.datatables.net/1.11.5/js/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jszip/2.5.0/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/1.11.5/js/jquery.dataTables.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.2.2/js/dataTables.buttons.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.2.2/js/buttons.html5.min.js"></script>
<script type="text/javascript" src="https://cdn.datatables.net/buttons/2.2.2/js/buttons.print.min.js"></script>

2. 在表声明中，您有两次相同的exportOptions，而不是定义两次，而是将它们组合为一个，如下所示：

{
extend:'print',
text:'Print',
"className": 'all_button',
// "autoPrint": false,
exportOptions: {
stripHtml: true,
modifier: {
page: 'current'
}
},
},
