I am currently working on developing a filter set, and I am facing an issue with the salesChannels array content in my view. The array only gets populated after clicking a button that triggers the test() function. Interestingly, the first time I log the array in ngOnInit, it shows up empty, but it works fine after clicking the button. The getOrganisationChannels function returns an observable.
What is causing this behavior and how can I handle it correctly? I attempted to use an eventEmitter to trigger the population process, but that did not yield the desired result.
TYPESCRIPT
export class SalesChannelFilterComponent implements OnInit {
constructor(
public organizationService: OrganizationService
) { }
@Input() organizationId: any;
salesChannels: Array<any> = [];
selectedChannels: Array<any> = [];
allSelected: Array<any> = [];
ngOnInit() {
this.getChannels();
console.log(this.salesChannels);
}
getChannels() {
this.organizationService.getOrganizationChannels(this.organizationId).subscribe(
salesChannels => {
this.salesChannels = salesChannels;
})
}
test() {
console.log(this.salesChannels);
}
}
HTML
<div>
{{ salesChannels | json }}
</div>
<button (click)="test()">test</button>
<div *ngFor="let channel of salesChannels; let i = index;" class="checkbox c-checkbox">
<label>
<input type="checkbox">
<span class="fa fa-check"></span>{{channel.name}}
</label>
</div>
