ViewChild您可以使用它ViewChildren来获取该页面中滑块的所有实例(Angular docs),而不是.请看看这个工作的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;

  constructor() {}

  public move(index: number): void {
    this.slides.toArray()[index].slideNext(500);
  }      

}

然后在视图中:
