Yes you can ! :-)

var elements = {
    element : {
            date: {
                 day: 'Monday'
            }
    }
}

function getObjectByStringIdentifier ( stringId ) {
    
    //return elements[stringId];
    //            ^      ^  
    //            |      |  
    //            |------|---------------------------------------------|  
    //                   |                                             |
    //        -----------|                                             | 
    //        |                                                        |
    //        °                                                        °
    return stringId.split('.').reduce(function(t,v){return t[v]; } , elements)
}


/** let's test it now ! **/

var stringIdentifier = "element.date.day";
var result = getObjectByStringIdentifier( stringIdentifier );


document.getElementById('el').innerHTML = result;
