Unable to load data inside ngOnInit

Question

My goal is to load a dropdown when a component renders. I have a service which hits a url and gets json data. Something like this

 @Injectable()
 export class St         


        

Answer 1

ngOnInit() {
       setTimeout(()=>
          {
            this.studentListService.getStudent().subscribe(response =>{
             this.items = response;
          },error=>{
           console.log(error);
         });
     },1000);
 }
