Possible duplicate:JavaScript: delete item by ID
I know only their identifiers and do not know specifically about their parent nodes ....
You can use parentNodefor an element to get its parent element, and use removeChildon it.
parentNode
removeChild
var el = document.getElementById( 'id' ); el.parentNode.removeChild( el );
In jQuery will work only $('#your_id').remove();.
$('#your_id').remove();
