The FormControlDirective is used to synchronize a standalone FormControl instance to a form control element
<form [FormControlDirective] ="name">

Selectors:
Approach:
- Create the Angular app to be used
- In app.component.ts make an object that contains a value for the input.
- In app.component.html use FormControlDirective to get values.
- Serve the angular app using ng serve to see the output.
Example:
app.component.ts
import { Component, Inject } from '@angular/core' ;
import { FormGroup, FormControl, FormArray } from '@angular/forms'
@Component({
selector: 'app-root' ,
templateUrl: './app.component.html' ,
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
geek: FormControl = new FormControl( '' );
}
|
app.component.html
< br >
< input [formControl]="geek">
< p >Value: {{ geek.value }}</ p >
|
