                        else if (RtObject.CId == -1) {
                            jAlert(RtObject.Message, "Failure");
                        }
                    }
                },
                failure: function (response) {
                    jAlert("Cant go to payment process", "Failure");
                }
            });

        });

please help me to solve this.

Instead window.location = RtObject.ReturnVal; use window.open(RtObject.ReturnVal, '_blank');
