The real problem is: How to get row of table using id?
真正的问题是：如何使用id?
The method fnGetPosition($('#row'+id+'-tr')isn't returning row.
该方法fnGetPosition($('#row'+id+'-tr')不返回行。
I put this code before calling fngetPosition: console.log($('#row'+id+'-tr'))and
returns: ({length:1, 0:({}), context:({}), selector:"#row1-tr"})
我在调用 fngetPosition: 之前放置了这段代码console.log($('#row'+id+'-tr'))并返回：({length:1, 0:({}), context:({}), selector:"#row1-tr"})
Thanks for help!
感谢帮助！

Looking at the jquery.dataTables source code around line 1903, it seems to me that $('#row'+id+'-tr')does return an empty object in your case. This means that the selector does not exist on your page.
查看第 1903 行附近的 jquery.dataTables 源代码，在我看来，$('#row'+id+'-tr')在您的情况下确实返回了一个空对象。这意味着您的页面上不存在选择器。
You can verify this by putting a console.log($('#row'+id+'-tr'))before the oTable.fnDeleteRow(
您可以通过console.log($('#row'+id+'-tr'))在oTable.fnDeleteRow(
