ts中标红的代码是前面html标红的相呼应，然后addScrollEventListener进行滚动的监听 注意： ionViewDidLoad()这个是ionic3本身的方法，只要触动页面，就能调用这个方法，无论点击还是拉动。
然后就是
this.scroll2._scrollContent.nativeElement.onscroll = event => {
this.scroll3._scrollContent.nativeElement.scrollTop =this.scroll2._scrollContent.nativeElement.scrollTop;
// this.scroll1._scrollContent.nativeElement.scrollLeft =this.scroll2._scrollContent.nativeElement.scrollLeft;
}就是监听事件，只要滑动就能触发的事件
