jQuery: How to make function in an object public?

I use a pagination plugin and I'd like to make one of it's functions public, so I can call it from "outside". I can not call it di开发者_如何转开发rectly, using pageSelected($(obj)).

Is there an easy way to make it visible so I can call it?

window is the global object in JavaScript, so do window.myfunc = myfunc and myfunc will be available globally.

Have a look at line 818 of the jQuery core source to see an example of this in action:

// Expose jQuery to the global object
window.jQuery = window.$ = jQuery;

You could also use a more Object-Oriented way to write plugins.

Hector Virgen posted a great approach on his blog:

Plugin code:

(function($){

   var MyPlugin = function(element, options)
   {
       var elem = $(element);
       var obj = this;
       var settings = $.extend({
           param: 'defaultValue'
       }, options || {});

       // Public method - can be called from client code
       this.publicMethod = function()
       {
           console.log('public method called!');
       };

       // Private method - can only be called from within this object
       var privateMethod = function()
       {
           console.log('private method called!');
       };
   };

   $.fn.myplugin = function(options)
   {
       return this.each(function()
       {
           var element = $(this);

           // Return early if this element already has a plugin instance
           if (element.data('myplugin')) return;

           // pass options to plugin constructor
           var myplugin = new MyPlugin(this, options);

           // Store plugin object in this element's data
           element.data('myplugin', myplugin);
       });
   };

})(jQuery);

Calling the plugin:

$('#test').myplugin();
var myplugin = $('#test').data('myplugin');
myplugin.publicMethod(); // prints "publicMethod() called!" to console
