errors.email = 'Required';
} else if (!/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i.test(values.email)) {
errors.email = 'Invalid email address';
}
if (!values.password) {
errors.password = 'Required';
}
return errors;
}}
onSubmit={(values, { setSubmitting }) => {
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
setSubmitting(false);
}, 400);
}}
>
{({ isSubmitting }) => (
<Form>
<div className="form-group">
<label htmlFor="email">Email</label>
<Field type="email" name="email" className="form-control" />

)}
</Formik>
);
};
export default MyForm;

<div>
<label for="email">Email</label>
<input id="email" v-model="email" @blur="validateEmail" />
<span v-if="errors.email">{{ errors.email }}</span>
</div>
<div>
<label for="password">Password</label>
<input id="password" type="password" v-model="password" @blur="validatePassword" />
<span v-if="errors.password">{{ errors.password }}</span>
</div>
<button type="submit">Submit</button>
</form>

</template>
<script>
import { required, email } from 'vee-validate/dist/rules';
import { extend, validate } from 'vee-validate';
extend('required', {

});
extend('email', {
...email,
message: 'Invalid email address'
});
export default {
data() {
return {
email: '',
password: '',
errors: {}
};
},
methods: {
validateEmail() {
this.errors.email = validate(this.email, 'required|email');
},
validatePassword() {
this.errors.password = validate(this.password, 'required');
},
submitForm() {
this.validateEmail();
this.validatePassword();
if (!this.errors.email && !this.errors.password) {
alert('Form submitted successfully!');
}
}
}
