（ this ）.attr（' name'）。slice（ 9 ， - 1）;
itemqty =

(this).attr('name').slice(9, -1); itemqty =

（ this ）。value;


if （ window .XMLHttpRequest）{
xmlhttp1 = new XMLHttpRequest（）;
}
xmlhttp1.onreadystatechange = function （）{
if （xmlhttp1.readyState == 4 && xmlhttp.status == 200 ）{
document .getElementById（ cart1 ）.innerHTML = xmlhttp1.responseText;
}
}
alert（itemname）;
xmlhttp1.open（ GET， php / updateqty.php？order = 238& id = + itemname + & qty = + itemqty， true ）;
xmlhttp1.send（）;
}
