Array in Array Angular ReactiveForms

1 answer

I am trying to insert an array of tags in reactive form, however I get an array in an array

logically, I have a form, on the form there is a button that calls up a separate modal window, for adding representative contacts, I want to collect these contacts into an array, which I then transfer to the main form

The model is as follows

export class RepresentativesModel {     id: number;     surname: string;     name: string;     middleName: string;     email: string;     phone: string[] }     

component is as follows

representativesArray: RepresentativesModel[] = [];  this.formBasic ={   id: 0,   name: [''],         representatives: this.fb.array([]) }); 

Submit Button logics

const RepresentativeItems = this.formBasic.get('representatives') as FormArray;  this.representativesArray.forEach(element => {   const phones = new FormArray([     new FormControl(   ])   RepresentativeItems.push({     id:,     surname: element.surname,     name:,     middleName: element.middleName,     email:,     phone: phones   })); }); 

HTML Controls is as follows

<div class="col-md-12">     <label for="phone">Contact Phones</label>     <tag-input formControlName="phone"         [modelAsStrings]="true"         theme='primary'>     </tag-input> </div> 

The result that I get, a little confuses me and I do not know how to solve it

{   "id": 0,   "name": "",     "representatives": [     {       "id": 0,       "surname": "First Name",       "name": "Last Name",       "middleName": "Middle Name",       "email": "[email protected]",       "phone": [                      <-- ARRAY 1          [                            <-- ARRAY 2             "123456",             "654321",             "1111"          ]       ]     }   ] } 

but how to fix this array in an array?

The best answer:

Use formBuilder array method should solve your problem. Your this part of code is creating nested array

 const phones = new FormArray([    new FormControl(  ]) 

change to this

const phones = this.fb.array(;
