首先在html中的写法是
<ion-header>
<ion-navbar>
<ion-title>历史数据</ion-title>
</ion-navbar>
</ion-header>
<ion-content >
<div style="display:flex;width:625px;">
<div class="head">地区</div>
<div style="overflow: hidden;white-space: nowrap;width:250px;height: 50px;" >
<ion-scroll #scroll1 scrollX="true" overflow-scroll="true" has-bouncing="false" (onScroll)="addScrollEventListener()" style="margin-top:0;height:50px">
<div style="display:flex;width:500px;height:50px" id="right">
<div class="head" >到件量</div>
<div class="head">出仓量</div>
<div class="head">滞留量</div>
<div class="head" style="border-right:0;">未派送量</div>
</div>
</ion-scroll>
</div>
</div>
<div style="display:flex;width:625px;height: 650px;white-space: nowrap;" >
<ion-scroll #scroll2 scrollY="true" overflow-scroll="true" has-bouncing="false" style="height:550px;width: 125px">
<div *ngFor="let d of data" class="head" >
{{d.zoneName}}
</div>
</ion-scroll>
<div style="overflow: hidden;white-space: nowrap;width:250px">
<ion-scroll direction="xy" #scroll3 scrollX="true" scrollY="true" overflow-scroll="false" has-bouncing="false" delegate-handle="rightContainerHandle" style="height:550px;">
<div style="width:500px;" >
<div *ngFor="let d of data" style="display:flex;" >
<div class="head" >
{{d.arriveTickets}}
</div>
<div class="head">
{{d.moniOutCnt}}
</div>
<div class="head">
{{d.moniStayCnt}}
</div>
<div class="head" style="border-right:0;">
{{d.moniUndeliveryCnt}}
</div>
</div>
</div>
</ion-scroll>
</div>
</div>
</ion-content>
标红颜色的首先是在ts中滚动时需要用到的变量，是个标识符。这个问题我纠结了两天才搞出来。一定记得滚动的监听事件不是on-scroll了

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
