1. Because I'm sure it'll come in handy later, here's a javascript object clone function:

   function clone(obj){
    if(obj == null || typeof(obj) != 'object')
        return obj;

    var temp = {};
    for(var key in obj)
        temp[key] = clone(obj[key]);
    return temp;
}


   Update: From feedback in the comments, a better version is:

   function clone(obj){
    if(obj == null || typeof(obj) != 'object')
        return obj;

    var temp = new obj.constructor(); // changed (twice)
    for(var key in obj)
        temp[key] = clone(obj[key]);

    return temp;
}
