Hi everyone,
I have recently entered the Angular world and I am running into a problem
that I really can't solve.
I created a service called UsersService where inside I invoke a rest
service that returns the list of registered users.
getUtenti() : Utente[]{
let data = this.http.get(this.API).subscribe((data) => {
let output = data['utenti'];
for (var i = 0; i < output.length; i++){
let utente = <Utente> output[i];
this.listaUtenti.push(utente);
}
});
I call this method from a component.ts
getUtenti(){
this.listaUtenti = this.serviceUtente.getUtenti();
console.log("Risultato utenti" +JSON.stringify(this.listaUtenti));
The getUtents does not wait for the "this.serviceUtente.getUsenti ()" to
end and consequently the User list will always be empty.
In fact if I put a timeout to my getUsers it works.
setTimeout(() => {
console.log("Risultato utenti" +JSON.stringify(this.listaUtenti));
}, 300);
I was wondering, is there a way to solve this problem or do I have to play
with event emitters? Thanks a lot to everyone
