Question

I know how to append or prepend a new row into a table using jquery:

$('#my_table > tbody:last').append(html);

How to I insert the row (given in the html variable) into a specific “row index” i. So if i=3, for instance, the row will be inserted as the 4th row in the table.

Answer 1

You can use .eq() and .after() like this:

$('#my_table > tbody > tr').eq(i-1).after(html);

The indexes are 0 based, so to be the 4th row, you need i-1, since .eq(3) would be the 4th row, you need to go back to the 3rd row (2) and insert .after() that.
