how to redirect or call routerlink in ts file in angular2

Question

This is angular 2 routing code

     <nav>          <ul class="nav nav-tabs">         <li role="presentation" class="active"><a routerLink="/dashboard" routerLinkActive="active">Step I</a></li>         <li role="presentation"> <a routerLink="/faculty" routerLinkActive="active">Step II</a></li>         <li role="presentation"><a routerLink="/heroes" routerLinkActive="active">Step III</a></li>         </ul>               </nav>     <router-outlet></router-outlet> 

button click event

clickFunctionEvent(value: any) {        this.dataService.setFacultyAnswer(JSON.stringify(value)).subscribe(       tradeshows => {             this.data= tradeshows          //if data=success then redirect to next routerLink like "/faculty"                          },       error => {console.error('QuestionList:\n\t ' + error);}     ); } 

if data=success then redirect to next routerLink like "/faculty"

so how to it in .ts file

And how to disable previous routerLink so not allow to go back

thanks in advance

Answer 1

you use

 //in your constructor   constructor(public router: Router){}  //navigation link.  this.router.navigate(['your-route']);
