首先在html中的写法是

历史数据

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中的代码

import { Component, SystemJsNgModuleLoader,HostListener,NgZone ,ViewChild } from '@angular/core';

import { NavController, NavParams,IonicPageModule} from 'ionic-angular';

import{RestProvider} from '../../providers/rest/rest';

import {Http,Response, Jsonp} from '@angular/http';

import { IonicModule } from 'ionic-angular';

import { NgModule, ErrorHandler ,CUSTOM_ELEMENTS_SCHEMA, SchemaMetadata} from '@angular/core';

import { Directive, ElementRef, Output,Input, EventEmitter } from '@angular/core';

import { ScrollEventModule,ScrollEvent } from 'ngx-scroll-event';

import {Content,Scroll,Spinner} from 'ionic-angular'

import { asElementData } from '@angular/core/src/view';

/**

* Generated class for the AlarmPage page.

*

* See https://ionicframework.com/docs/components/#navigation for more info on

* Ionic pages and navigation.

*/

@Component({

selector: 'page-rank',

templateUrl: 'rank.html',

})

@NgModule({

imports: [IonicModule,IonicPageModule,ScrollEventModule]

})

export class RankPage {

@Output() scrollChange = new EventEmitter();

@ViewChild(Spinner) spinnerElement: Spinner;

@ViewChild(Content) content: Content;

@ViewChild('scroll3') scroll3: Scroll;

@ViewChild('scroll1') scroll1: Scroll;

@ViewChild('scroll2') scroll2: Scroll;

//括号中的值在html页面中标注的时候，名称不能其他属性相同。如该文件已经有一个pnavs的变量，则会报错。

addScrollEventListener() {

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;

}

this.scroll1._scrollContent.nativeElement.onscroll = event => {

//this.scroll3._scrollContent.nativeElement.scrollTop =this.scroll2._scrollContent.nativeElement.scrollTop;

this.scroll3._scrollContent.nativeElement.scrollLeft =this.scroll1._scrollContent.nativeElement.scrollLeft;

}

this.scroll3._scrollContent.nativeElement.onscroll = event => {

this.scroll2._scrollContent.nativeElement.scrollTop =this.scroll3._scrollContent.nativeElement.scrollTop;

this.scroll1._scrollContent.nativeElement.scrollLeft =this.scroll3._scrollContent.nativeElement.scrollLeft;

}

}

ionViewDidLoad() {

this.addScrollEventListener();

}

}

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
