How to extract a string value from an observable array in Angular2 NativeScript?

I inserted JSON data into an observable array. My goal is to extract only the address from ShowData, specifically as a string value based on its position.

ShowData.ts:

 class ShowData{

  constructor(public id:number, public name:string, public address:string, public code:string) {
  }

 }

ts file:

  private arrList: ObservableArray<ShowData> = new ObservableArray<ShowData>();

openData(pos : number){    --->listview item position


   let getValue: any = this.arrList.get(pos);  // this is not worked


}

When accessing the arrList based on the listview item position, I need to retrieve only the address value.

Answer №1

When working with observable arrays, it is important to use the method .getItem instead of .get to retrieve items from the array.

openData(pos : number){   
   let getValue: any = this.arrList.getItem(pos).address;
}

Answer №2

For those seeking the address, this code snippet may be of assistance:

retrieveAddress(position : number){    
   let addressValue: any = this.arrayList[position].address;
}
