如何为web应用程序管理ionic2中的多个滑块？

Question

我有这样的html用于幻灯片

<ion-slides   [pager]="false" slidesPerView="6" #slider_a>
        <ion-slide  *ngFor="let slide of  items_a " #ddd>
            <ion-card class="list-card" >
                <div class="cardInnerWrap">
                    <ion-item>
                      {{slide.gameTitle}}
                    </ion-item>
                     <img src="{{slide.gameImage}}">

                </div>
            </ion-card>
        </ion-slide>
</ion-slides>

<ion-slides   [pager]="false" slidesPerView="6" #slider_b>
        <ion-slide  *ngFor="let slide of  items_b " #ddd>
            <ion-card class="list-card" >
                <div class="cardInnerWrap">
                    <ion-item>
                      {{slide.gameTitle}}
                    </ion-item>
                     <img src="{{slide.gameImage}}">

                </div>
            </ion-card>
        </ion-slide>
</ion-slides>

它在移动设备上工作。问题是，当我拖动幻灯片2在火狐(也在铬)，幻灯片1也被拖动。不能单独拖动幻灯片2。如何使在浏览器中工作的离子2中2完全独立的滑块

更新，感谢来自Slack频道的@cookiecookson：

1. 链接到github问题
2. 链接到解决此问题的PR (截至2017年6月27日尚未合并)

似乎这是Ionic实现Swiper包装器中的一个bug。解决这个问题的一种方法是为Swiper库使用另一个包装器，就像这一个一样。您可以在这个github回购. 中找到一个演示应用程序

最终的结果将是这样的：

首先你需要安装它

npm install angular2-swiper --save

然后将其导入app.module.ts文件(或您想要的模块中)

import { KSSwiperModule } from 'angular2-swiper';

// ...

@NgModule({
  declarations: [...],
  imports: [KSSwiperModule, ...],
  bootstrap: [...],
  entryComponents: [..],
  providers: [...]
})
export class AppModule { }

然后在你的页面上使用它。

组件代码：

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  public items_a: Array<any>;
  public items_b: Array<any>;

  public options: any;

  constructor(public navCtrl: NavController) {
    this.items_a = [
      { gameTitle: 'Title1', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title2', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title3', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title4', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title5', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title6', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title7', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title8', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title9', gameImage: 'http://via.placeholder.com/200x200' }
    ];

    this.items_b = [
      { gameTitle: 'Title10', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title11', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title12', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title13', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title14', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title15', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title16', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title17', gameImage: 'http://via.placeholder.com/200x200' },
      { gameTitle: 'Title18', gameImage: 'http://via.placeholder.com/200x200' }
    ];

    this.options = {
      slidesPerView: 3
    }
  }

}

查看：

<ion-header>
    <ion-navbar>
        <ion-title>
            Multiple slides
        </ion-title>
    </ion-navbar>
</ion-header>

<ion-content padding>

    <ks-swiper-container [options]="options">
        <ks-swiper-slide *ngFor="let slide of items_a">
            <ion-card class="list-card">
                <div class="cardInnerWrap">
                    <ion-item>
                        {{ slide.gameTitle }}
                    </ion-item>
                    <img src="{{ slide.gameImage }}">
                </div>
            </ion-card>
        </ks-swiper-slide>
    </ks-swiper-container>

    <ks-swiper-container [options]="options">
        <ks-swiper-slide *ngFor="let slide of items_b">
            <ion-card class="list-card">
                <div class="cardInnerWrap">
                    <ion-item>
                        {{ slide.gameTitle }}
                    </ion-item>
                    <img src="{{ slide.gameImage }}">
                </div>
            </ion-card>
        </ks-swiper-slide>
