Try this:

The method returns an object, that contains the parts.

function getPath(obj, value, path){
    path = path || [];   
    if(obj instanceof Array || obj instanceof Object){
        //Search within children
        for(var i in obj){
           path.push(i); //push path, will be pop() if no found
            var subPath = getPath(obj[i], value, path);
            //We found nothing in children
            if(subPath instanceof Array){
                if(subPath.length == 1 && subPath[0]==i){
                  path.pop();   
                }
            //We found something in children
            }else if(subPath instanceof Object){
               path = subPath;                
               break;   
            }
        }
    }else{
        //Match ?
        if(obj == value){            
            return {finalPath:path};   
        }else{
            //not ->backtrack
            path.pop();
            return false;   
        }
    } 
    return path;
}

Maybe its not the best code, took me 10min there but it should work.

To see any result, check your dev console F12.
