One*_*ror 1 javascript datatable jquery
我正在使用jQuery DataTable创建网页。我有一个用例，其中打开的页面已填充表格。现在，页面上有一个表单，他可以在其中放置一些过滤器并刷新表格。另外，更重要的是，对于每一行，我可以展开以查看更多详细信息，如此处所述。
就我而言，提交表单后重新加载数据后，用于扩展每个数据行的详细信息按钮将停止工作。它给出以下错误：
jquery.dataTables.min.js：120未捕获的TypeError：无法读取未定义的属性'_detailsShow'
我通过先清除，销毁然后调用DataTable方法来重新加载您的表。这是我的代码：

有人可以指出我做错了吗。在此先感谢一吨。这已经困扰了我一段时间了。

这个对我有用。只需通过添加.off删除最新的click事件处理程序，然后再添加新的事件处理程序即可。
$(dashboard_table_id).find('tbody').off('click', 'tr td.details-control');
$(dashboard_table_id).find('tbody').on('click', 'tr td.details-control',function(){...});
