Plumbing code to hook up Mkay to jQuery.Validate.

mkay.jquery.js

jQuery.validator.addMethod("mkay", function (value, element, param) {
    "use strict";
    var ruledata = JSON && JSON.parse(param) || $.parseJSON(param);
    var validator = MKAY.getValidator(ruledata.rule, ruledata.ast);
    return validator();
});

jQuery.validator.unobtrusive.adapters.add("mkay", ["rule"], function (options) {
    "use strict";
    options.rules.mkay = options.params.rule;
    options.messages.mkay = options.message;
});
