How to display json object using *ngFor and access

Question

I want to display the below data from Server in ionic 2. and access key and value of object using *ngFor.

i want to display this object dynamically using *ngFor. how to get it ?

Is there a simpler solution to this problem because I feel that it would be really common for developers using Angular2 to display such json data.

Answer 1

to print Admiranda array in *ngfor loop, first write one pipe

Pipe.ts

@Pipe({
  name: 'objectValues'
})
export class ObjectValuesPipe implements PipeTransform {
  transform(obj: any) {
    let result = [];
    for (var key in obj) {
      if (obj.hasOwnProperty(key)) {
        result.push(obj[key]);
      }
    }
    return result;
  }
}

do not forget to import your pipes in @NgModule, than you can use this pipe like this.

<ul *ngFor="let item of items">
   <li *ngFor="let value of item | objectValues">
     {{ value }}
   </li>
 </ul>
