Rails spinoffs - Mar 2006 - problems with ".this"

Hello I´m making a class using prototype''s class.create(), like this:
var onewClass = Class.create();
onewClass.prototype = {
    initialize : function(array) {
        this.variable = "fooo";
        this.array = array;
    },
    function1 : function() {
        this.array.each(function(element){
                       alert(element);
                       alert(this.variable);
                  });
    }
};

and I intance it like this:
var array = ("house", "car", "tree");
var newClass = new onewClass(array);
newClass.function1();
The problem is that the alerts appear, but this.variable says
"undefined",
how can i do to make it say "fooo", as is declarated in the initialize
part?
Thank you and sorry for my english :) :) !!

this.array.each((function(element){
                       alert(element);
                       alert(this.variable);
                  }).bind(this));


Hope this helps,

Thank you Nicolas!! your soluction worked wonderfull.
Now I have another cuestion related to this: I have a class with an object
inside:

var onewClass = Class.create();
onewClass.prototype = {
   initialize : function() {
       this.variable = "fooo";
   },
   myrules : {"fooo" : this.variable
   }
};
and I intance it like this:
var newClass = new onewClass();
if I do alert(newClass.myrules.fooo) it doesn´t show "fooo". How can I
do to
correct this? Thank you!!

This may have just been a typo by you, but I think you just need to
remove the quotes from the "fooo" in your object...

 

var onewClass = Class.create();
onewClass.prototype = {
   initialize : function() {
       this.variable = "fooo";
   },
   myrules : {fooo: this.variable
   }
};

fooo is being set at "compile time" to this.variable which
isn''t
defined until you call new onewClass().

Just define this.myrules in initialize() and you should be able to
access them via newClass.myrules like in your example.

Ryan, the quotes around fooo are valid syntax.
