@ -83,6 +83,18 @@ All validators return `false` if the required validity state is met.
All validators are considered self explanatory due to their explicit namings.
You can implement your own custom message for a default validator. Pass a getMessage function via the options in the construtor.
```js
function getCustomMessage(data) {
return `${data.name} is a required field`;
}
```
```html
<validatable-el .validators="${[new Required({}, { getMessage: getCustomMessage })]}"></validatable-el>
```
