When navigating to a child component from the parent component's HTML template using a button, how can I pass the parent component's data (such as a name) to the child component without displaying it in the URL?
From what I gather from your inquiry, it seems you are looking to transmit data from the parent route to the child route without revealing the actual URL and without using router links to prevent displaying the true links. If this is the case, you can implement the following approach:
In your HTML file, incorporate a button styled like a link using Bootstrap 4, and include an onclick function as shown below:
<button type="button" class="btn btn-link" (click)="gotoChildRoute()">Link</button>
Within the gotoChildRoute() method, utilize routing in the following manner:
this.route.navigate(['childroute'], {skipLocationChange: true});
If you opt for using a link, you can set skipLocationChange as demonstrated below:
<a [routerLink]="['/childroute']" replaceUrl="false" skipLocationChange="true"></a>
I trust this information will be beneficial to you.
Consider utilizing a service to share the state across your components.
To begin, set up a service:
@Injectable()
export class DataSharingService {
data: string;
}
You can then integrate this service in both the source and target components.
@Component({
...
})
export class SourceComponent {
constructor(private dataService: DataSharingService) {}
onAction() {
dataService.data = "Some Information";
// Navigate to your component.
}
}
This is how you can access the data:
@Component({
...
})
export class TargetComponent {
data: string;
constructor(private dataService: DataSharingService) {}
ngOnInit() {
this.data = this.dataService.data;
}
}
Don't forget to include DataSharingService in the main module:
@NgModule({
imports: [ ... ],
providers: [ DataSharingService ],
declarations: [ SourceComponent, TargetComponent ]
})

When your child component is nested within your parent component, you have the option to send data as an input parameter. For more information, visit: https://angular.io/api/core/Input
To pass data from your parent component to the child component, follow these steps:
<child-component [inputdata]="yourDataObject">
In this code snippet, "inputdata" is a customizable name and "yourDataObject" represents the data attribute you wish to transfer to the child component. In your child component, access the passed data using the following syntax:
@Input('inputdata') passedData;
Remember to ensure that the name matches what was specified in the parent component.
