Blue Meanie

No form is safe in Pepperland.

What is Blue Meanie?

Blue Meanie is a simple form validation engine. It accepts rules, validates form elements (event based), and triggers events. It does not care how you render error messages or maintain state. It is a jQuery plugin, of course.

Disclaimer

As of publishing, 01/10/2013, Blue Meanie has some rough edges and needs some improvement. Blue Meanie is currently being used in a limited case. Blue Meanie will be refined as/if the scope of usage increases. Blue Meanie is being used as part of larger validation library that contains state management and rendering modules. The modules are then tied together through a common API. Documentation and examples will be added as time permits.

How Does it Work?

It listens for certain DOM events and validates when the events occur.

First thing you will need are some rules. Rules can be loaded like so:

$.fn.meanie('addRule', { // this will add the rule to the plugin itself not an instance of the plugin, so that rules can be shared with all instances
    name: 'required',
    msg: 'This field is required.',
    test: function (target, options) {
        // target is the input being validated
        // an options argument can be defined when a rule set is created (see example later on)
        return true; // this should return a boolean value
    }
});

Now that we have a rule lets validate a form:

$('form').meanie({
    rulesets: [ // there can be an infinite number of rule sets that contain an infinite number of rules
        {
            qrysel: 'input[type="text"]', // THIS IS COOL: apply this rule to all elements that match this query selector
            rules: [
                {
                    // use the required rule we defined above; options is an optional argument;
                    // options will be passed as an argument to validation function (see addRule example above)
                    { name: 'required', options: {} },
                    { name: 'number' } // pretend this rule has already been defined
                }
            ]
        }
    ]
});

Lets listen for validation events:

$('form').on('meanie.validate', function (event, verdicts) {
    // when an input is validated an event is triggered
    // an array of verditc objects is returned; each object cotains the following properties
    // $target, msg, options, rules, valid
});

Validate this element:

// returns an array of verdict objects
$('form').meanie('validate', target, silent); // target is a DOM element; silent is a bool indicating whether an event should be triggered

Let me see all the rules:

$('form').meanie('rules');

No longer validate this element:

$('form').meanie('remove', target); // target is a DOM element

We are done validating. Lets remove the validation:

$('form').meanie('destroy');
