Call a function inside ngFor in angular2

Question

Hello I am using Angular2 and wanted to fetch the server and get some values for each ID I get inside ngFor.

Answer 1

Doesn't sound very good , however , the simplest way :

   here call a function that do something with 'item' and return something new 

Proper way :

@Directive({
  selector: '[runDummyFunc]'
})
export class runDummyFunc {

  constructor() {}
  ngOnInit() {      
     this.runDummyFunc()
  } 

}



     here call a function that do something with 'item' and return something new 

In your class :

      myFunction = ():void=>{

         console.log('whatever');
      }
