ANGULAR 15 : CREATE DYNAMIC CONTROLS IN REACTIVE FORMS

In this tutorial, we will see how to add the form controls in the html at runtime using formarray in reactive forms in Angular 10.
Here we will just take an example of the Mobile numbers in form.
When the user clicks on add new mobile button, the new mobile input textboxes will be generated at runtime. The user can then enter there alternative mobile numbers.
We will also see how to fetch those values from the runtime generated textboxes.

Example of FormArray in Reactive from :

userprofileForm = this.fb.group({
firstName: ['', Validators.required],
lastName: [''],
address: this.fb.group({
address1: [''],
address2: [''],
state: [''],
zip: ['']
}),

mobiles: this.fb.array([
this.fb.control('')
])
});

Here mobiles is the formarray.
We will now see how to add the formcontrols in this formarray at runtime and display those controls in Html.
Also we will see how to fetch the values from those runtime controls.
