javascript - 如何在数据表中启用复制、PDF、Excel 按钮

Question

我想启用复制、PDF、Excel 按钮，这样它看起来像这样:

这是我的代码，但未能将其发布:

<table id="example" class="display" width="100%">

之前我们可以使用TableTools but now it's called Button .

在此代码中，您可以找到完整的运行代码。不是那个代码我已经included “按钮”的 CSS 和 JS功能。正确的做法是什么？

Answer 1

DataTables Buttons extension默认情况下不提供。所以一定要将它添加到您的依赖项中(有关更多信息，请参见链接)。 “Excel”、“PDF”等导出按钮需要“Flash 导出”或“HTML5 导出”代码或两者都在 Download builder 中.

并且您必须告诉 DataTables 在何处插入按钮。您有两个选择:

• 在dom中包含字符B选项，例如 dom: 'Bfrtip'
• 使用 $('#example').DataTable().buttons() 获取包含按钮的 jQuery 集合并将其插入到您想要的位置。
