Question

relipse has a good point - as you are cluttering the main namespace. A solution if you have more objects than just eg. MessageBox is to create your own namespace like this:

jQuery.myLib = {
  MessageBox: function() {
    var show = function() {
      // something...
    }
    var hide = function() {
      // something...
    }
    return {
      show: show,
      hide: hide
    }
  }
}

That means you are only taking one place in the main namespace (the name of your library, in this case myLib). You'd call it like this:

jQuery.myLib.MessageBox.show()
