JSON Question

How to display json object using *ngFor and access key,value of object

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

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

@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>
