Angular 2 change image src attribute

Question

Assuming I have the following code:

Answer 1

Add a imgSrc in your component

class Component {
 constructor(jwtService: JwtService) {
     this.imgSrc = JwtService.characterImage(enemy);
 }
}

<img [src]="imgSrc" 
        class="{{enemy.status}}"
    (click)="sidenav.toggle();" style="cursor:pointer">

Answer 2

You could pass a reference of your tag using $event and change it's attribute from your typescript code.

<img (click)="functionInTypeScript($event.target)">

Or if you want to change something in image tag on another event you could do it like this

<img #image>
<button (click)=functionInTypeScript(image)>

and then simply access in typescript code like this

functioninTypeScript(image:any) {
   image.src='path to new image';
}

Answer 3

Typescript:

getImage(image: any, time: string) {
    const t1 = '06:00';
    const t2 = '18:00';
    if (time >= t1 && time < t2) {
      return ('/images/morning.png');
    } else {
      return ('/images/evening.png');
    }
  }

HTML :

  <img [src]="getImage(this,bettrainList.departureTime)" width="25">
