How about this (untested):

function bubbleUpNodes(a) // where a is array of IDs
{
	for ( x=1; x<a.length; x++) // bubble first to last by swapping  
adjacent nodes and IDs throughout the array
	{
		var tempId = a[x-1]; // prepare to swap IDs
		swapNodes( document.getElementById(a[x-1]) , document.getElementById 
(a[x]) ); // swap nodes
		a[x-1] = a[x]; // swap IDs
		a[x] = tempId; // swap IDs
	}
}

Peace,
