页面加载时此动画有效,但是我需要在单击按钮时对此图像进行动画处理
<div [@fadeInDownOnEnter]="'true'">
<img src="https://www.seoclerk.com/pics/556744-1wYpi51504622425.jpg" alt="animatepic">
</div>
<button (click)="animate()">Animate it</button>
在component.ts文件中
import { fadeInDownOnEnterAnimation } from 'angular-animations';
@Component({
animations: [
fadeInDownOnEnterAnimation()
]
})
//method
animate(){
//what should I do here
}

在您的组件中,
animationWithState = false;
animate(){
this.animationState=true;
this.animationWithState = !this.animationWithState;
}, 1);
和
<div [@fadeInDownOnEnter]="'true'">
应该像
<div [@fadeInDownOnEnter]="animationState">

将模板'true'
的值设置为一个变量,而不是模板中的静态值[@fadeInDownOnEnter]
,像这样
<div [@fadeInDownOnEnter]="animationState" >
<img src="https://www.seoclerk.com/pics/556744-1wYpi51504622425.jpg" alt="animatepic">
</div>
<button (click)="animate()" >Animate it</button>
然后在您的组件中
import {fadeInDownOnEnterAnimation} from 'angular-animations';
@Component({
animations:[
fadeInDownOnEnterAnimation()
]
})
animationState = 'true';
//method
animate(){
//what should I do here
this.animationState = this.animationState === 'true' ? 'false' : 'true';
// the code above will toggle the value of animationState between 'true' and 'false'
// in order to update the animation
}
