input-validation

Very simple universal input validation module

This module has zero dependencies, is extensible and uses data attributes to target validation conditions

Getting Started

1. Installation (node)

npm install input-validation

2. Examples

    var validatior require('input-validation'),
        handlers = {
            blur: function(target) {
                target.className = validator.validate(target) ? '' : 'invalid';
            }
        }
   

    <input name="email" data-required data-valid-email onblur="handlers.onblur(this)">

• data-required The user must supply some value to for the input to be valid

    <input data-required>

• data-valid-email The user must supply a loosely valid email for the input to be valid

    <input data-valid-email>

Adding new validators

When extending input validation with new validators use camelCase without 'data' when specifying the attribute name.

    
    var validatior require('input-validation');
    
    validator.add('greaterThanTen', function(value) {
        return value !== undefined && parseInt(value,10) > 10;
    })
    

The user must supply an int value greater than 10

    <input data-greater-than-ten>
