Trouble extending Validator

[NoumanSaleem]

When running my custom 'validState' validation, the param 'str' comes out as undefined.

Any idea?

When the methods are chained together you can access the string with this.str rather than as a parameter

Validator.prototype.validState = function () {
    if (states.indexOf(this.str) === -1) {
        this.error(this.msg || 'Invalid state');
    }
    return this;
}

//then
check('AK').validState();
