How to use

    To bind on form submit event.
    var validator = new FormValidator('example_form', [{
        name: 'req',
        display: 'required',
        rules: 'required'
    }, {
        name: 'alphanumeric',
        rules: 'alpha_numeric'
    }, {
        name: 'password',
        rules: 'required'
    }, {
        name: 'password_confirm',
        display: 'password confirmation',
        rules: 'required|matches[password]'
    }, {
        name: 'email',
        rules: 'valid_email'
    }, {
        name: 'minlength',
        display: 'min length',
        rules: 'min_length[8]'
    }, {
        names: ['fname', 'lname'],
        rules: 'required|alpha'
    }], function(errors) {
        if (errors.length > 0) {
            // Show the errors
        }
    }); 

With autload you need to add inline attributes
data-yavjs-rules = same syntax as in the declaration of the rules
data-yavjs-display = The display name to use in message else name is used
data-yavjs-on = a json compose of 2 property : on:eventName, callback
The callback of data-yavajs-on receive two parameter, the event and errorObject

errorObject =   id: field.id,
                display: field.display,
                element: field.element,
                name: field.name,
                message: message,
                messages: [],
                rule: method
