How to access variables from a class using static methods?

Question

//my class
function myClass()
{
   this.pubVar = 'hello public';
   var priVar = 'hello private';


}

myClass.staticMethod = function()
{

   //how do i access thos variables here

}

I tried alert(this.pubVar), and alert(priVar)without success. What am I doing wrong?

I will change the question a little. I did not explain this for the first time.

How to declare static variables in a class?

I know that with java it's simple, you just put a static infront of type variable and presto, you have a static variable. I can not find this parameter for javascript ..

Answer 1

Definition:

myClass.staticMethod = function(obj)
{
    alert(obj.pubVar);
}

Using:

var instance = new myClass();
myClass.staticMethod(instance);

You cannot use "priVar" since it is not a class variable. This is a scope variable.

Also, if you need to access class properties, why are you making it a static method?
