次奥,form的onsubmit中加入了ajax后引发的问题


<form id="frmCreatSupplier" runat="server" method="post" action="CreatSupplier.aspx" onsubmit="supplierSubmit()" >function supplierSubmit() {
            var num = "false";
            SetIds();
            $.ajax({
                type: "post",
                url: "../CheckValidator.ashx",//验证码验证
                data: { validator: $("#txtValidator").val() },
                success: function (msg) {
                    num = msg;                    if (num != "true") {                        $("#txtValidator").css("border-color", "red");
                        alert(num);
                        return false;
                    }
                    return true;
                    //document.forms[0].submit();
                },
                error: function (msg) {
                    alert("other validator check false");
                }
            });
        }
在form onsubmit的ajax执行后后台PageLoad怎么也不执行了ajax onsubmitAjaxonsubmit
