Navigating through an array in Angular 5: a guide

This question may seem simple, but I'm having trouble figuring it out.

Here is the code snippet I am working with:

getInstabul(): void {
    this.homeService.getWeather()
    .subscribe((weather) => {

      this.instanbulWeathers = weather
      // console.log(this.instanbulWeathers);
    });

Within my service, I have the following code:

getWeather(): Observable<any>{

    return this.http.get<any>(this.getWeatherUrl())
    .pipe(
      tap(weather => console.log(weather || 'not working')),
      catchError(this.handleError('getWeather', []))

      // this.getWeatherDetails();
    );

After running the code, it returns the following response:

[…]
​
0: Object { title: "Istanbul", location_type: "City", woeid: 2344116, … }
​
length: 1
​
<prototype>: Array []

However, when attempting to access [weather.title], no value is displayed in the console. I need to retrieve this value to pass to another function within the component.

If anyone could provide assistance, especially since I am new to Angular, it would be greatly appreciated.

Answer №1

climate is a single-item collection, therefore utilize {{ cityClimates[0].name }} within your template.

Alternatively, assign cityClimates to climate[0] and subsequently {{ cityClimates.name }} will function in your template.
