Accessing Nested FormGroup in Angular 6 by its name

Dealing with Nested Form Groups

address = new FormGroup({
'com.complex.Address':new FormGroup({
            city: cityControl,
            streetName: streetNameControl,
            houseNumberAddition: houseNumberAdditionControl,
            houseNumber: houseNumberControl,
            postcode: postcodeControl
          })
});

In search of the nested form group labeled "com.complex.Address".

My attempts so far:

this.form.get('address').get('com.complex.Address');

Unfortunately, this always returns a Null value.

As a workaround, if I change the nested form group's name to something like "test" and run

this.form.get('address').get('test');
, it actually returns the desired value.

However, changing the nested name is not an option, especially if it contains special characters.

Is there a way to escape these characters and use the form group as intended?

Answer №1

Examining the angular code of the .get() function, it appears to use "." as a delimiter to create an array of paths.

In this situation, there doesn't seem to be a clear solution to navigate through it. However, an alternative approach could be to use :

(<FormGroup>this.form.get('address')).controls['com.complex.Address']; 

Answer №2

give it a shot this way

 BuildForm = this.fb.group({
        partnerId: this.fb.group({
            key: [null, Validators.required]
        })});

this.BuildForm.get('partnerId').value.key  
this.BuildForm.get('partnerId').get('key').value`
