qty in text input field. every qty text field name unique detail code. need every time change qty field, updates session array unigue detail code.
how can on jquery without submitting form?

sorry bad english, omerimuni

this code has been taken (and modified slightly) another answer - should solve problem. try -

$('input:text[id*="qty"]').bind('keyup',function() {     $.post("my_other_script.php", { qty: this.id} ); });

'my_other_script.php' -

<?php $_session['qty'] = $_post['qty']; ?>
