jQuery: count number of rows in a table

2018-06-30 00:48:48

How do I count the number of tr elements within a table using jQuery?

I know there is a similar question, but I just want the total rows.

Use a selector that will select all the rows and take the length.

var rowCount = $('#myTable tr').length;

Note: this approach also counts all trs of every nested table!

如果您在表中使用<tbody>或<tfoot> ，则必须使用以下语法，否则您将得到不正确的值：

var rowCount = $('#myTable >tbody >tr').length;

Alternatively...

var rowCount = $('table#myTable tr:last').index() + 1;

This will ensure that any nested table-rows are not also counted.
