First, set up the input fields you want:
<form @submit.prevent="login(event.target)">
<input name='username' class='form-control' data-validate="required|len[3,16]|alphanum|nospace">
</form>
then, trigger the plugin:
login: function(e) {
$(e).validate(function(result) {
if (result.success) {
alert('Success!');
} else {
alert(result.msg);
}
})
}
