Pass dynamic click handler to Angular button












0















I have the following Angular code in my component which works out from a service which buttons to display:



buttons: any;
private buttonsSubscription: Subscription;

ngOnInit() {
this.buttonsSubscription = this.toolbarService.getButtons().subscribe((buttons: any) => {
this.buttons = buttons;
});

}


And then in my html I do the following:



<li *ngIf="buttons && buttons.length>0" class="buttons">
<span *ngFor="let button of buttons">
<a [routerLink]="[button.link]" title="{{button.text}}"><span>{{button.text}}</span></a>
</span>
</li>


I'd like to include a button.onclick item, so some buttons will have Delete(), others may have Print().



How do I pass this to my html?



This is what I want to do (but obviously doesn't work):



<a (click)="{{button.onclick}}" title="{{button.text}}"><span>{{button.text}}</span></a>

You can configure something like this [routerLink]="['/', button.link]"



HTML:



<li *ngIf="buttons && buttons.length>0" class="buttons">
<span *ngFor="let button of buttons">
<a [routerLink]="['/', button.link] title="{{button.text}}"><span>{{button.text}}</span></a>
</span>




if you want to add a button, then you can add a click event and call a method from TS to route it.



  <li *ngIf="buttons && buttons.length>0" class="buttons">
<span *ngFor="let button of buttons">
<button (click)="routeButton(button)">Click ME</button>
</span>
</li>


TS:



   routeButton(button){
this._router.navigateByUrl(button.link);
}
