我正在使用离子3同时在同一页面上放置3个滑动滑块我无法分别控制它们的行为我对角度js以及ts和离子有点新
这是代码
<ion-slides style="height: 30%;" pager>
<ion-slide style="background-color: green" *ngFor="let post of posts">
<h1>{{post.title}}</h1>
<img [src]="post.image" />
</ion-slide>
</ion-slides>
<ion-slides style="height: 30%;" pager>
<ion-slide style="background-color: green" *ngFor="let post of posts">
<h1>{{post.title}}</h1>
<img [src]="post.image" />
</ion-slide>
</ion-slides>
ts是
@ViewChild(Slides) slides: Slides;
goToSlide() {
this.slides.slideTo(2, 500);
}
ngAfterViewInit() {
//this.slides.freeMode = true;
this.slides .slidesPerView=3,
this.slides.spaceBetween=5;
//this.slides.loop=true;
}
您可以使用ViewChild
来获取该页面中滑块的所有实例(ViewChildren
),而不是Angular docs。请看看this working plunker。最终结果将是这样的:
就像你在plunker中看到的那样,我们得到了滑块的所有实例,然后我们通过使用它的索引来获取目标实例:
import { Component, ViewChildren, QueryList } from '@angular/core';
import { NavController, Content, Slides } from 'ionic-angular';
@Component({...})
export class HomePage {
@ViewChildren(Slides) slides: QueryList<Slides>;
constructor() {}
public move(index: number): void {
this.slides.toArray()[index].slideNext(500);
}
}
然后在视图中:
<ion-header>
<ion-navbar>
<ion-title>Ionic Demo</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
<ion-slides style="height: 75px" pager>
<ion-slide><h1>Slide 1</h1></ion-slide>
<ion-slide><h1>Slide 2</h1></ion-slide>
<ion-slide><h1>Slide 3</h1></ion-slide>
</ion-slides>
<ion-slides style="height: 75px" pager>
<ion-slide><h1>Slide 1</h1></ion-slide>
<ion-slide><h1>Slide 2</h1></ion-slide>
<ion-slide><h1>Slide 3</h1></ion-slide>
</ion-slides>
<ion-slides style="height: 75px" pager>
<ion-slide><h1>Slide 1</h1></ion-slide>
<ion-slide><h1>Slide 2</h1></ion-slide>
<ion-slide><h1>Slide 3</h1></ion-slide>
</ion-slides>
<ion-row>
<ion-col>
<button (click)="move(0)" ion-button text-only>Move First</button>
</ion-col>
<ion-col>
<button (click)="move(1)" ion-button text-only>Move Second</button>

<ion-col>
<button (click)="move(2)" ion-button text-only>Move Third</button>
