click the button and increase number through component - angular
19,348
Solution 1
Try it:
public getCount() {
return this.counterService.count
}
public incCount(){
this.counterService.count += 1;
}
in html:
<button (click)="incCount()" class="btn btn-default form-control increaseBtn">INCREASE</button>
and in counter.service:
export class CounterService {
public count = 0;
}
But better manage variables in service
Solution 2
app.component.ts
<button type="text" class="btn btn-primary" (click)="onShowLog()">Click Me</button>
<p *ngIf="showLog">{{ log }}</p>
app.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.sass']
})
export class AppComponent {
log = 0;
showLog = false;
onShowLog(){
this.showLog = true;
return this.log = this.log + 1;
}
}

Hej, I'm having having a problem with button which should increase number +=1 and display in the view this number.
app.component.ts
import { Component } from '@angular/core'; import { CounterService } from '../common/services/counter.service'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.sass'] }) export class AppComponent { constructor(private counterService: CounterService) {} get count() { return this.counterService } set count(count){ this.counterService.count += 1; } }
counter.service
export class CounterService { count = 0; }
app.component.html
<div class="container"> <div> <p> {{ counterService.count }}</p> <button (click)="count()" class="btn btn-default form-control increaseBtn">INCREASE</button> </div> </div>
I can display 0 but when I'm stacked with incrementation. Thx in advance!
