I want to pass data on button click of parent component to child component and render child component as a separate page in angular 5 instead of rendering child component in parent's template.

Suppose, My child component is 'AstronautComponent' and when I add ,

<app-astronaut *ngFor="let astronaut of astronauts"
  [astronaut]="astronaut">
</app-astronaut >

this in parent template it is showing child template on same page instead of separate page.Actually I am able to get data from parent to child but on same parent template.I am using @Input annotation with service(as Observable).

Kindly Help.

Thanks

  • What do you mean by separate page? Is it a new tab in the browser altogether?
  • if you're opening a new page, I believe router params are your only option. but why use a single page application framework like angular and not use a single page is beyond me
  • @AnkitSharma Yes, it's a new tab.If parent is at 127.0.0.1:4200/parent then new tab at 127.0.0.1:4200/astronaut.
  • @Stavm As you suggested will go through router params.But do I achieve a parent template is fully replaced by child template using SPA?If yes then please tell how do it?
  • @NareshPawar - Did the solution help?
