Validation().isValid

The isValid accessor property returns the current validity state of the Validation object.

Value

A Boolean value.

Description

This property returns true when all predicate groups of the Validation are in the “valid” state. After creation of an instance of Validation, this property is set to false, except for validations created with the parameter optional=true for which it is set to true by default.

Examples

import { Validation } from 'isomorphic-validation';

// validatable objects
const obj1 = { value: '' };
const obj2 = { value: '' };

// predicate functions
const hasCapitalLetters = (value) => /[A-Z]/.test(value);
const hasNumbers = (value) => /[0-9]/.test(value);

const validation1 = Validation(obj1)
    .constraint(hasCapitalLetters);

const validation2 = Validation(obj2)
    .constraint(hasNumbers);

const validationGr = Validation.group(validation1, validation2);

const validations = { validation1, validation2, validationGr };

obj1.value = 'asdf';
obj2.value = 'asdf';
await validationGr.validate();
console.table(validations, ['isValid']);

obj1.value = 'asdf';
obj2.value = 'asdf1';
await validationGr.validate();
console.table(validations, ['isValid']);

obj1.value = 'asdfG';
obj2.value = 'asdf1';
await validationGr.validate();
console.table(validations, ['isValid']);
