first modal:

href="http://localhost/pe//aprove/download/4"

second modal:

href="http://localhost/pe//aprove/download/41"

i need to refresh the table to make it just get their own id

Answer 1

So do something like

<a type="button" id="down" data-href="<?php echo base_url(); ?>/aprove/download/">Berkas</a>

and read the data attribute

var anchor = modal.find('#down')
anchor.attr('href', anchor.data('href') + div.data('id'));
