扫过段标签 - Ionic 3 [英] Swipe through segment tabs - Ionic 3

问题描述

下面的代码使用了 ionic 3 中的片段.文档显示了 ngSwitch、ngModel 的使用.但我想简单地在细分上滑动并切换到另一个细分选项卡.我怎样才能做到这一点?

我对滑动顶部的选项卡不感兴趣，但通过滑动内容我想更改分段选项卡.

<离子内容填充>
<离子段[(ngModel)]="abc"><ion-segment-button value="Segment1">段标题</离子段按钮><ion-segment-button value="segment2">段标题</离子段按钮></离子段></div><div [ngSwitch]="abc"><ion-list *ngSwitchCase="'segment2'" class="list-fixed"><离子项目><ion-thumbnail item-start><img src="assets/imgs/1.jpg"></离子缩略图><h2>列表项 1</h2><p>列表项副标题</p><button ion-button clear item-end>查看</button></离子项目></离子列表><ion-list *ngSwitchCase="'segment1'" class="list-fixed"><离子项目><ion-thumbnail item-start><img src="assets/imgs/3.png"></离子缩略图><h2>列表项标题 1</h2><p>副标题</p><button ion-button clear item-end>查看</button></离子项目></离子列表></div>

解决方案

我的解决方案是添加:

.html 文件

//在您想检测用户输入的滑动的地方添加以下代码//当用户进行滑动时，只需检查并在选项卡之间进行切换.(pan)='swipeEvent($event)'

.ts 文件

pages: string = "pageA";滑动事件($e){控制台.log($e.deltaX+", "+$e.deltaY);如果($e.deltaX > 0){console.log("从左向右滑动");this.pages = "pageB";}别的{console.log("从右向左滑动");this.pages = "pageA";}}

The code below uses segments from ionic 3. docs show the use of ngSwitch, ngModel. but I would like to simply swipe on the segment and switch to another segment tab. How can I achieve this?

I am not interested in swiping the tabs at the top but by swiping on the content i would like to change the segment tab.

<ion-content padding>

  <div>
    <ion-segment [(ngModel)]="abc">
      <ion-segment-button value="Segment1">
        Segment Title
      </ion-segment-button>
      <ion-segment-button value="segment2">
        Segment Title
      </ion-segment-button>
    </ion-segment>
  </div>

  <div [ngSwitch]="abc">
    <ion-list *ngSwitchCase="'segment2'" class="list-fixed">
      <ion-item>
        <ion-thumbnail item-start>
          <img src="assets/imgs/1.jpg">
        </ion-thumbnail>
        <h2>List Item 1</h2>
        <p>List Item Subtitle</p>
        <button ion-button clear item-end>View</button>
      </ion-item>
    </ion-list>

    <ion-list *ngSwitchCase="'segment1'" class="list-fixed">
      <ion-item>
        <ion-thumbnail item-start>
          <img src="assets/imgs/3.png">
        </ion-thumbnail>
        <h2>List Item Title 1</h2>
        <p>Subheading</p>
        <button ion-button clear item-end>View</button>
      </ion-item>
    </ion-list>
  </div>

解决方案

My Solution was to Add :

.html file

//Add below code where you would like to detect the swipe from users input
// When user makes a swipe simply check and do the switch between Tabs.

(pan)='swipeEvent($event)' 

.ts file

pages: string = "pageA";

swipeEvent($e) {
    console.log($e.deltaX+", "+$e.deltaY);
    if($e.deltaX > 0){
      console.log("Swipe from Left to Right");
      this.pages = "pageB";
    }else{
      console.log("Swipe from Right to Left");
      this.pages = "pageA";
    }
}
