errorMessage: true,
successClass: true,
language: "https://emretulek.github.io/jbvalidator/dist/lang/en.json"
});
//custom validate methode
validator.validator.custom = function(el, event){
if($(el).is('[name=password]') && $(el).val().length < 5){
return 'Your password is too weak.';
}
}
validator.validator.example = function(el, event){
if($(el).is('[name=username]') && $(el).val().length < 3){
return 'Your username is too short.';
}
