inEnum

The value must be one of a TypeScript enum's numeric values. The control value is coerced numerically; non-numeric values fail.

Signature

NguardValidators.Number.inEnum(enumObject: Record<string, string | number>): ValidatorFn

Parameter	Type	Description
enumObject	Record<string, string | number>	The enum to check membership against

Reactive forms

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

enum Priority {
    Low = 1,
    High = 5,
}

new FormControl('', [NguardValidators.Number.inEnum(Priority)]);

Template-driven forms

<input ngModel name="priority" [nguardNumberInEnum]="Priority" />

Error key

{ inEnum: true }

Notes

• Membership is checked against the enum's values. The reverse-mapping keys numeric enums generate are filtered out, so a key number like 3 (absent from the values) correctly fails.
