So, you want to update the name of input with name id0 in second last row?

$('#myTable tr:last-child').prev().find(' td input[name="id0"]').attr('name', 'id1');

Unlike the .eq(index) method, the :eq(index) selector does not accept a negative value for index. For example, while $('li').eq(-1) selects the last li element, $('li:eq(-1)') selects nothing.

Try this :
$('#myTable tr').eq(-2).find('input[name="id0"]').attr('name', 'id1');

That code does not find name id0 in second last row ONLY.  it searches entire table.

I want to update the name of input with name id0 in second last row only. I dont want to search other places
