首先要在Component裏引入對應的組件:
immport { trigger, state, style, animate, transition } from "@angular/animations";
然後就可以在你@Component註入器寫你的animation代碼:
@Component({ selector: "hero", templateUrl: "./hero.html", styleUrls: ["./hero.scss"], encapsulation: ViewEncapsulation.None, animations: [ trigger("signal",[ state("hide", style({ "height": 0, "background-color": "green" })), state("show": style({ "height": "100px", "background-color": "yellow" })), transition("*=>*",animate(500)) ]) ] })
聲明signal
export class hero {
public signal: string;
}
html的結構
<div [@signal]="signal"></div>
<button (click)="hide()">hide</button>
<button (click)="show()">show</button>
最後在創建hide、show方法觸發就可以了
hide() { this.signal = "hide" } show() { this.signal = "show" }
