undefined value from function??

[crabby80]

Hi guys

Any ideas why this is returning undefined?

function get_question_id(element,needle) {
    
    parentElement = element.parentNode;
    
    if(parentElement.className == needle) {
        for(i=0; i<parentElement.childNodes.length; i++) {
            if(parentElement.childNodes[i].id == "question_id" ) {
                alert(parentElement.childNodes[i].value); // ok
                return parentElement.childNodes[i].value;
            }
        }
    } else {
        get_question_id(parentElement,needle);
    }
}

function add_answer(element) {
    alert(get_question_id(element,'question')); // undefined
}

Can you show a relevant html code?

[Kravvitz]

    } else {
        get_question_id(parentElement,needle);
    }

needs to be

    } else {
        return get_question_id(parentElement,needle);
    }
