I am working on an Angular class and I need to create a method that can retrieve a value from an observable and assign it to multiple class properties. Below is a snippet of my code:
export class SomeServiceClass implements OnInit {
someProperty1: someObject;
someProperty2: someObject;
somePropertyN: someObject;
ngOnInit() {
this.someProperty1 = getValueFromObservableGenericMethod("value1")
this.someProperty2 = getValueFromObservableGenericMethod("value2")
this.somePropertyN = getValueFromObservableGenericMethod("valueN")
console.log(someProperty1); // undefined
console.log(someProperty2); // undefined
console.log(someProperty3); // undefined
}
getValueFromObservableGenericMethod(someIncomingString: string): someObject {
let localVar: someObject;
this.anotherServiceClass.subscribe(
data => {
localVar = data;
},
() => {
return localVar;;
console.log(localVar);
}
)
return localVar;
}
}
After calling the method, all my class properties are showing as undefined. The variable localVar is available in the complete function. Does anyone have any suggestions on how to properly return values from this function call?
