Hi,
I call this observable metod (it works):
constructor(private Servizio: Services) {
}
ngOnInit() {
this.getUtenti();
//this.utente.ute = this.Utenti[0] ;
//this.utente.azienda = this.Utenti['azienda'];
//this.utente.anno = this.Utenti['anno'];
}
getUtenti() {
this.Servizio.getUtente()
.subscribe(
Utenti => this.Utenti = Utenti,
error => this.errorMessage = <any>error);
}
If I use the ngFor it works well:
<h2 *ngFor="let utente of Utenti">
<h2>Operatore: {{utente.utente}}</h2>
<h2>Azienda: {{utente.azienda}}</h2>
<h2>Esercizio: {{utente.anno}}</h2>
</h2>
I would take the individual elements of the array, like this:
this.utente.utente = this.Utenti[0].utente
but I have the error:
*core.umd.js:3427 EXCEPTION: Cannot read property 'utente' of undefined*
or: *EXCEPTION: Cannot read property '0' of undefined*
Data from Observable is a file.json like this:
{
"data": [
{ "utente": "UTE", "azienda": "01", "anno": "2016"}
]
}
Thanks.
