doesntContain

Validate that the array contains none of the given values (membership via Array.includes). A non-array value fails.

Signature​

NguardValidators.Array.doesntContain(...values: primitive[]): ValidatorFn
ParameterTypeDescription
...valuesprimitive[]The values that must all be absent

Reactive forms​

import { FormControl } from '@angular/forms';
import { NguardValidators } from 'ng-nguard';

new FormControl(['read'], [NguardValidators.Array.doesntContain('admin', 'root')]);

Template-driven forms​

<!-- Array form -->
<input ngModel name="scopes" [nguardArrayDoesntContain]="['admin', 'root']" />

<!-- Single value shorthand -->
<input ngModel name="scopes" [nguardArrayDoesntContain]="'admin'" />

The directive selector is nguardArrayDoesntContain (prefixed for symmetry with nguardArrayContains).

Error key​

{ doesntContain: true }

Notes​

  • Membership uses Array.prototype.includes (strict, SameValueZero).
  • A non-array value (including null/undefined) fails.
