Is there any way to retrieve span id? input element is embedded within span?

---

document.getElementById("inputId").parentNode;

---

If you're using jQuery:

$('#input-id').parent().attr('id');

If not:

document.getElementById('input-id').parentNode.getAttribute('id');

EDIT: Ooops - removed extra parentheses after parentNode!

---

var parentControl = document.getElementByID("id goes here").parentNode;
