When utilizing Vuelidate, the 'required' validator now accepts boolean 'false' as a valid value. To enforce required validation for checkboxes, you must use 'sameAs' such as sameAs: sameAs( () => true ). How can 'requiredUnless' validation be implemented for checkboxes in Vuelidate? In this scenario, the checkbox is only mandated to be checked if a specific property does not hold a certain value.
The system currently recognizes "false" as a valid input, so it is necessary to update it to an empty string. I will implement this adjustment in the watch function:
data() {
return {
email: '',
age: null,
password: '',
confirmPassword: '',
country: 'Malta',
hobbyInputs: [],
terms: '',
countries,
}
},
validations: {
terms: {
required: requiredUnless(vm => {
return vm.country === 'Malta'
}),
}
},
watch: {
terms() {
if (!this.terms) {
this.terms = '';
}
}
},
Struggling to find a way to validate with vuelidate, I decided to create a method that toggles a css class by executing a function and passing the $v object to it. Validation is only triggered when the value is not a selected option.
<div class="input inline" :class="{invalid: checkCountry($v)}">
The validation logic:
Validations: {
terms: {
sameAs: sameAs(vm => {
if (!(vm.country === 'germany')) {
return true;
} else {
return false;
}
})
The method:
methods: {
checkCountry($v) {
if (this.country === 'germany') {
return false;
} else {
return $v.terms.$invalid;
}
}
