如何在 ionic2 中为 Web 应用程序管理多个滑块?

问题描述

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

   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}}}

   查看:

   <ion-header><离子导航栏><离子标题>多张幻灯片</离子标题></离子导航栏></离子头><离子含量填充><ks-swiper-container [options]="options"><ks-swiper-slide *ngFor="让items_a滑动"><ion-card class="list-card"><div class="cardInnerWrap"><离子项目>{{ slide.gameTitle }}</离子项目><img src="{{ slide.gameImage }}"></div></离子卡></ks-swiper-slide></ks-swiper-container><ks-swiper-container [options]="options"><ks-swiper-slide *ngFor="让items_b滑动"><ion-card class="list-card"><div class="cardInnerWrap"><离子项目>{{ slide.gameTitle }}</离子项目><img src="{{ slide.gameImage }}"></div></离子卡></ks-swiper-slide></ks-swiper-container></离子含量>

   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>
   

   its working in mobile device. problem is when i drag slide 2 in Firefox(also in chrome) , slide 1 also getting dragged. cant drag slide 2 alone. How can i make 2 completely independent slider in ionic 2 that work in browser

   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
       }
     }
   
   }
   

   View:
