我正在使用角度动画生成器来创建动画。我有一个带有卡片列表的网格列表。当我点击一个按钮时，我希望另一个div出现在初始卡片的顶部（从左侧浮动以覆盖第一张卡片） ）。到目前为止，div带有动画，但是显示在初始卡片的侧面。我制作了一个stackblitz示例来显示当前进度。这是我的stackblitz：
https://stackblitz.com/edit/angular-ty4rfh
也将代码粘贴到此处：
import { Component,OnInit,ElementRef } from '@angular/core';
import { trigger, state, style, transition, animate, AnimationBuilder, AnimationPlayer } from '@angular/animations';
export class Asset
{
constructor(public name:string,public description:string){};
}
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
name = 'Angular';
assets:Asset[]=[];
cards=[];
private player: AnimationPlayer;
constructor(private animationBuilder:AnimationBuilder,
private elRef:ElementRef
){}
ngOnInit(){
this.setAssets();
this.setswitch();
}
setAssets(){
this.assets.push(new Asset("Asset1","Latest1"));
this.assets.push(new Asset("Asset2","Latest2"));
this.assets.push(new Asset("Asset3","Latest3"));
this.assets.push(new Asset("Asset4","Latest4"));
this.assets.push(new Asset("Asset5","Latest5"));
this.assets.push(new Asset("Asset6","Latest6"));
this.assets.push(new Asset("Asset7","Latest7"));
this.assets.push(new Asset("Asset8","Latest8"));
this.assets.push(new Asset("Asset9","Latest9"));
for(var i=0; i<this.assets.length;i++){
console.log(this.assets[i].name);
}
}
setswitch() {
for (let i = 0; i < this.assets.length; i++) {
let cardshow = {
id: i.toString(),
isShow : false
};
this.cards.push(cardshow);
}
console.log(this.cards);
}
animate(i){
this.cards[i].isShow=true;
let animationFactory;
animationFactory = this.animationBuilder
.build([
style({ width: '0' }),
animate(200, style({ width: 200 }))
]);
let elem:Element = document.getElementById("div"+(i));
console.log("Elament",elem);
console.log("INDEX",i);
this.player = animationFactory.create(elem);
this.player.play();
}
}
html：
<div>
<mat-grid-list cols="3" rowHeight="3:1">
<mat-grid-tile *ngFor="let asset of assets; index as i">
<div class="border">
<p>{{asset.name}} </p>
<p>{{asset.description}} </p>
<button (click)="animate(i)">click</button>
</div>
<div [ngClass]="!cards[i].isShow?'hide':''" id="{{'div'+i}}" class="border" >
<p>{{asset.description}} </p>
<button>click</button>
</div>
</mat-grid-tile>
</mat-grid-list>
</div>
css：
p {
font-family: Lato;
}
.border{
border:1px solid black;
padding-left: 20px;;
padding-right:20px;
}
.hide{
display:none;
}
编辑：我需要将另一张卡片完全隐藏在收到的卡片下方。此外，在点击收到的卡片内的按钮后，动画应撤消（该卡片应退回）。另外，我现在正在做的是增加宽度。我期望新卡应该像我们在抽屉中看到的那样从左侧进来

选中此stackblitz
app.component.css 为：
p {
font-family: Lato;
}
.border{
border:1px solid black;
padding-left: 20px;;
padding-right:20px;
background: #ffe6ea;
}
.hide{
display:none;
}
.borderPopUp{
padding-left: 20px;;
padding-right:20px;
position:absolute;
background:#d3d3d3d4;
animation: openLikeDrawer 800ms ease-in-out;
width:50%;
left:20%;
}
@keyframes openLikeDrawer{
from {left:0px; }
to { left: 20%; }
}
app.component.html 为：
<div>
<mat-grid-list cols="3" rowHeight="3:1">
<mat-grid-tile *ngFor="let asset of assets; index as i">
<div class="border">
<p>{{asset.name}} </p>
<p>{{asset.description}} </p>
<button (click)="asset.isShow = true">click</button>
</div>
<div *ngIf="asset.isShow" class="borderPopUp" >
<p>{{asset.description}} </p>
<button (click)='asset.isShow = false'>click</button>
</div>
</mat-grid-tile>
</mat-grid-list>
</div>
