Looping through all instances of a javascript object

and I make some cats:

Answer 1

since i just had a similar problem, here's one easy solution if you use jquery:

function Cat(color, sex){
     this.color = color;
     this.sex = sex;
}

var cats = [];
function createCat(color, sex)
{
    cats.push(new Cat(color, sex)));
}

createCat("white", "male");
createCat("black", "female");

//iterating cats by using jQuery's $.each
$.each(cats, function(index, object){
        alert(object.color);
});
