Description
Note that support for using the ngModel
input property and ngModelChange
event with reactive
form directives was deprecated in Angular v6 and is scheduled for removal in
a future version of Angular.
For details, see Deprecated features.
The following example shows how to register a standalone control and set its value.
import {Component} from '@angular/core';
import {FormControl, Validators} from '@angular/forms';
@Component({
selector: 'example-app',
template: `
<input [formControl]="control" />
<p>Value: {{ control.value }}</p>
<p>Validation status: {{ control.status }}</p>
<button (click)="setValue()">Set value</button>
`,
})
export class SimpleFormControl {
control: FormControl = new FormControl('value', Validators.minLength(2));
setValue() {
this.control.setValue('new value');
}
}
