Answer 1

You can do something like this :

var elements = {
    element : {
            date: {
                 day: 'Monday'
            }
    },
    cars : {
        racing : "Lamborghini",
        classic: "Rolls Royce"  
    }
}


function getObjectByStringIdentifier ( stringId ) {
    objects = stringId.split(".");
    element = elements; 
    for(i=0; i < objects.length; i++)
        element = element[objects[i]]; 
    return element;
}

alert(getObjectByStringIdentifier("cars.racing"));
alert(getObjectByStringIdentifier("element.date.day"));
alert(getObjectByStringIdentifier("cars.classic"));
