Global var with jquery plugin

Global var with jquery plugin

Hi all,

I make my personal plugin dialog because I can make a theme design with the jQuery UI dialog.

I want to use a global variable for each window dialog.

This is my code :

$.fn.myDialog = function(options)
{
      //  Options

      
   var zIndex   = 100;
   var settings = {
      
   };
   
   options = $.extend(settings, options);
   
      // Each   
   
   this.each(function()
   {
      init($(this));      
   });
   
   
   /*
    *         INIT
    ****************************************/
   
      // Init
   
   function init(me)
   {      
   
      alert(zIndex);
      zIndex++;
   }

   
};


But I have only 100 and never 101,102,...

What can I do for that ??

Thank you all
