I've adapter the answer of ltiong_sh to work for me:

function nextField(current){
    var elements = document.getElementById("my-form").elements;
    var exit = false;
    for(i = 0; i < elements.length; i++){   
        if (exit) {
            elements[i].focus();
            if (elements[i].type == 'text'){
                elements[i].select();
            }   
            break;
        }
        if (elements[i].isEqualNode(current)) { 
            exit = true;
        }       
    }
}
