jQuery Ajax在IE中不起作用

Question

i have the following function to add an article in my basket:

$(".addtocart").click(function(){

   var product = $("#pid").val();
   var qty = $("#qty").val();
   if(isNaN(qty) || qty == '') alert("ERROR");
   else{                                    
        alert("HIHI");

        $.ajax({
            type:"post",
            url:"index.php",
            data:"page=ajax&action=add_product&product=" + product + "&qty=" + qty,
            success: function(html){
                alert("AAA");
                /*
                $("#maininf").html($("#thumbimg").html());
                $("#tinfo").html(html);
                var leftPoint = (Fensterweite()-$(".readybuy").width())/2;
                $(".readybuy").css("left",leftPoint);
                $(".glassbox").fadeIn();
                $(".readybuy").fadeIn();
                */
            },
        });
   }

the first alert is alling everytime in IE. the beforeSend Step is working too. But the second alert is never coming. Has anybody an idea why it doesn't work on IE?

Thanks.

            $(".readybuy").fadeIn();
            */
        },  < - Extra comma will break IE
    });
