Calling a method function from a jQuery plugin

Give the following jQuery plugin:

(function($) {

  $.fn.prefCookie = function(method) {

    var options = {
      cookieName : 'prefs',
      actionType : 'click',
      key : '',
      value : false
    }

    var $obj;

    var methods = {

      init : function(config) {
        return this.each(function() {
          if(config) { $.extend(options, config) }
          $obj = $(this);
          options.value ? 
            $obj.bind(options.actionType,helpers.setPref) :
            $obj.bind(options.actionType,helpers.togglePref) ;
        });
      },

      anotherFunction : function() {
        console.log('you did it!');
      }

    }

    var helpers = {

      togglePref : function() {

      },

      setPref : function() {

      }

    }

    if (methods[method] && method.toLowerCase() != 'init') {
      return methods[method].apply(this, Array.prototype.slice.call(arguments, 1));
    } else if (typeof method === 'object' || !method) {
      return methods.init.apply(this, arguments);
    } else {
      $.error( 'Method "' +  method + '" does not exist in the Pref Cookie plugin!');
    }

  }

})(jQuery);

How can anotherFunction without attaching the plugin to anything. I'd like to do $.prefCookie.anotherFunction or something, but it doesn't work. Any suggestions?

It looks like you have set it up to handle the method call passed in by string.

If you want to do it as you say $.prefCookie.anotherFunction (which is different because there is no jQuery collection associated with it), try something like...

$.fn.prefCookie.anotherFunction = function() { }

jsFiddle.

$('your selector').prefCookie('anotherFunction'); should do it.

If you need to pass any parameters to anotherFunction, just add them after the string 'anotherFunction'.
