 var r = '';
        $.ajax({
            type: "POST",
            url: "webservice/DataService.asmx/GetAccount",
            data: "{AccountNo: '" + Code +"' }",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            //async: false, //假設沒有這行
            success: function(msg){
            if (msg.length > 0) { r = msg; }
            }
        });
