如何在 ionic2 中为 Web 应用程序管理多个滑块?

2022-01-13 00:00:00 javascript ionic3 angular typescript ionic2

我有这样的 html 用于幻灯片

它在移动设备中工作.问题是当我在 Firefox(也在 chrome 中)拖动幻灯片 2 时，幻灯片 1 也被拖动.不能单独拖动幻灯片 2.如何在浏览器中工作的 ionic 2 中制作 2 个完全独立的滑块

解决方案

更新感谢来自 Slack 频道的@cookiecookson:

  1. t

    首先你需要安装它

    npm install angular2-swiper --save

    然后将其导入到app.module.ts文件中(或者你想要的模块中)

    import { KSSwiperModule } from 'angular2-swiper';//...@NgModule({声明:[...]，进口:[KSSwiperModule，...]，引导程序:[...]，入口组件:[..]，供应商:[...]})导出类 AppModule { }

    然后在你的页面中使用它.

    组件代码:

    从'@angular/core'导入{组件}；从离子角度"导入 { NavController }；@零件({选择器:'page-home'，模板网址:'home.html'})导出类主页 {public items_a: 数组<any>;public items_b: 数组<any>;公共选项:任何；构造函数(公共 navCtrl:NavController){这个.items_a = [{游戏标题:'Title1'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title2'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title3'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title4'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title5'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title6'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title7'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title8'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title9'，游戏图像:'http://via.placeholder.com/200x200'}];this.items_b = [{游戏标题:'Title10'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title11'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title12'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title13'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title14'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title15'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title16'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title17'，游戏图像:'http://via.placeholder.com/200x200'}，{游戏标题:'Title18'，游戏图像:'http://via.placeholder.com/200x200'}];this.options = {slidesPerView: 3}}}

    I have html like this for slides

    <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>

    解决方案

    Update Thanks to @cookiecookson from Slack channel:

    1. link to the github issue
    2. link to a PR that fixes this issue (not yet merged as of 27/06/2017)

    Seems like it's a bug in Ionic's implementation of the Swiper wrapper. One way to solve it would be to use another wrapper for the Swiper library, just like this one. You can find a demo app in this github repo.

    The end result will be something like this:

    t

    First you'd need to install it

    npm install angular2-swiper --save

    Then import it in the app.module.ts file (or in the module you want)

    import { KSSwiperModule } from 'angular2-swiper';

// ...

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

    And then just use it in your page.

    Component code:

    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
    }
  }

}
