static variables in javascript

how can make static encapsulation self members in javascript? such in php:

class bar{       static public $foo;       static public function set() {             self::$foo = 'a';       } } bar::set(); 

in javascript: var bar = function () { ???????? } bar.set();

thanks!

simply define them properties of bar.

bar.foo = null; bar.set = function() {     bar.foo = "a"; } 

here's nice overview:

var bar = function() {     // private instance variables     var = 1;     // public instance variables     this.b = 5;     // privileged instance methods     this.c = function() {         return a;     } }; // public instance methods bar.prototype.d = function() {     return ++this.b; }  // public static variables bar.foo = null; // public static methods bar.set = function() {     bar.foo = "a"; }
