        yourOtherFunction: function (el, options) {
            // some logic
        }
    };

    // A really lightweight plugin wrapper around the constructor,
    // preventing against multiple instantiations
    $.fn[pluginName] = function (options) {
        return this.each(function () {
            if (!$.data(this, "plugin_" + pluginName)) {
                $.data(this, "plugin_" + pluginName, new Plugin(this, options));
            }
        });
    };

})(jQuery, window, document);

حال می خواهم برای قسمتهای زیر

 var upperCase = new RegExp('[A-Z]');
            var lowerCase = new RegExp('[a-z]');
            var numbers = new RegExp('[0-9]');
            var specialchars = new RegExp('([!,%,&,@,#,$,^,*,?,_,~])');

علاوه بر کلمات انگلیسی حروف فارس هم چک شود 
کد را باید چگونه تغییر بدهم
باتشکر
