如何获得被点击的表格行的TBODY？

Question

I have a table with a few rows in it. Each row has an onclick event that is supposed to check the ID of the tbody element. This is stored in a variable for later use in a function.

Right now I have this snippet of jQuery:

var parentTable = $(this.parentNode)[0].id;

However, this only gets the ID of the entire table, not the tbody .

What's the best way to specify the ID of the tbody element?

Answer 1

First, your use of jQuery is wasted there. It would be written like this:

var parentTable = this.parentNode.id;

As far as getting the tbody id, assuming this is actually the row, your code should do it.

If you're actually getting the table, then that would be very unusual. The only way a tbody would not get created would be if you manually created the table from DOM creation methods, and left it out.

Answer 2

您可能希望将该信息存储在每一行的data-tbody-id中，然后，当用户单击该行时，事件对象将保存该信息。

Answer 3

您可以使用以下功能

var tobody = parentTable.children('tbody')

Answer 4

You can use the following function

var tbody = $(this).parents("tbody");
var id = tbody.attr("id");
