ApproveJs

A simple validation library that doesn't interfere

ApproveJs doesn't automatically attach itself to input change events or form submit events. It also doesn't manipulate the DOM for you by automatically displaying errors. This allows you to automate validation how you want.

With a single method (approve.value()), you can decide how to handle validation.

If you like to be in control or have a little OCD like me, ApproveJs is for you.

ApproveJs is also easily extended with custom tests.

var approve = require('approvejs');

Usage

ApproveJS exposes a single method value that takes two parameters.

The first parameter is the value to validate and the second is the set of rules to test against.

var rules = {
    required: true,
    email: true
};

var result = approve.value('user@domain.com', rules);

The returned result contains two properties:

{
    approved: boolean,
    errors: []
}

Accessing Errors

You can access errors returned by the result in one of two ways:

Errors Property

var i = result.errors.length;
while(i--) {
    console.log(result.errors[i]);
}

`.each` Method

The result object exposes an each() method for easily getting to errors.

result.each(function(error) {
    console.log(error);
});
