What is the best way to retrieve the component object of the child components I am rendering in a list?

Within my component, I have a JSON payload containing a service. However, I am unsure of the best way to access the list items component objects from the parent component.

Answer №1

To achieve this functionality, utilize the ngFor loop.

 {
  "data": [
      {
        "id": "4",
        "name": " Name1"
      },
      {
        "id": "21",
        "name": " Name2"
      },
      {
        "id": "24",
        "name": " Name3"
      },
      {
        "id": "11",
        "name": " Name4"
      }
  ]
}

Incorporate the following HTML code:

<select>
    <option *ngFor="let item of data" 
    [value]="item.id" >
  {{item.name}}
</option>
</select>
