Custom validators

Adding custom validators is fairly simple, just add the function to the Rules object. The first argument of you function will always be the value of the input. The second one you will have to set yourelf, please note that this is the only parameter you can supply at this time.

const FormValidator = require('form-validator');

FormValidator.Rules.myRule = function(value, parameter){
    // Do whatever you want
    return true;
}

(function () {
    const myValidator = new FormValidator.FormValidator({
        'form': 'my-form',
        'rules': {
            'my-input': 'myRule:10'
        }
    });
})();
