                    // e.preventDefault();
                    var wheel = e.originalEvent.wheelDelta || -e.originalEvent.detail;
                    father2.scrollTop = father1.scrollTop-=wheel;
                    // var delta = Math.max(-1, Math.min(1, wheel) );
                    // if(wheel<0){//向下滚动
                    //     father.scrollTop+=10;
                    // }else{//向上滚动
                    //     father.scrollTop-=10;
