5、Ionic4 手势相关事件
详情参考:http://www.ionic.wang/article-index-id-155.html 1、首先需要安装 hammerjs
ionic4 中的 gestures 手势事件包括: tap, press, pan, swipe, rotate, and pinch events 等。详细使用方法参考:
详情参考:http://www.ionic.wang/article-index-id-155.html
1、首先需要安装 hammerjs
npm install hammerjs --save
2、在项目的 src/main.ts 中引入 hammerjs
import ‘hammerjs‘;
3、在项目中使用
<ion-button (press)="doPress()"> 长按触发的事件 </ion-button> <ion-button (tap)="doTap()"> 点击触发的事件 </ion-button>
说明:如果未来的 ionic4.x 版本可以直接使用手势事件的话忽略上面的安装引入过程。
