Populating a class object with all fields simultaneously from a FormGroup

Working with Angularjs projects involves creating an input form with various fields to collect data. The provided documentation includes examples on how to retrieve individual field values as well as how to save all the fields at once, potentially in a class or interface like Fruit. One important question to consider is whether the functionality will still function correctly if the number of fields in the Fruit interface differs from those in the fruitForm form.

fruit!: Fruit;

fruitForm = new FormGroup({
  name: new FormControl(),
  ... adding 5 additional fields
  series: new FormControl('series-01')
});
onFormSubmit(): void {
  console.log('Name:' + this.fruitForm.get('name').value);
  ...
  console.log('Series:' + this.fruitForm.get('series').value);
}

interface / class

export interface Fruit {
  id: number;
  name: string;
  ... there are 5 more fields
  series: string;
  data: Data;
}

Answer №1

To view all of them at once, you can use this.fruitForm.getRawValue();

Alternatively, if you want to loop through them and log their values similar to what you have in your code snippet:

Object.keys(this.fruitForm.controls).forEach(key => {
   console.log(key + ': ' + this.fruitForm.controls[key].value);
});
