Keep menu tree expanded after loading page

Is there a way to keep a menu tree expanded to the proper section after clicking a menu link and loading the page? For example, say I have this menu:

one
--one-a
--one-b
--one-c
----one-c-one
----one-c-two
two
--two-a
--two-b

...etc

If I click on one-c-one and load page one-c-one, I want the menu to stay expanded up to parent one-c. Is there a way to do this without using iframes?

Here is my javascript:

<script type="text/javascript">
function handleParent(parentId)
{
	myParent = document.getElementById("menu" + parentId)

	if (myParent.style.display=="none") {
		myParent.style.display="block"
	} else {
		myParent.style.display="none"
	}
}
</script>

Code (markup):

And a sample of my menu structure:

<div id="storemenu">	

	<menu id="booksandmovies">
	<li><a href="javascript:handleParent(1)">Books &amp; Movies</a>
	<menu id="menu1" style="display:none;">
			<li><a href="javascript:handleParent(2)">Books</a>
			<menu id="menu2" style="display:none;">
				<li><a href="javascript:handleParent(3)">Food</a>
				<menu id="menu3" style="display:none;">
					<li><a href="<?php echo get_permalink(175); ?>">Cookbooks</a></li>
					<li><a href="<?php echo get_permalink(176); ?>">Shopping</a></li>
					<li><a href="<?php echo get_permalink(177); ?>">Gardening</a></li>
					<li><a href="<?php echo get_permalink(174); ?>">Uncategorized</a></li>
				</menu><!-- menu3 -->
				</li>
				<li><a href="<?php echo get_permalink(178); ?>">Baby</a></li>
				<li><a href="<?php echo get_permalink(179); ?>">Kids Books</a></li>
				<li><a href="<?php echo get_permalink(180); ?>">Entertainment</a></li>
				<li><a href="<?php echo get_permalink(181); ?>">Health &amp; Beauty</a></li>
				<li><a href="<?php echo get_permalink(182); ?>">Home</a></li>
				<li><a href="<?php echo get_permalink(183); ?>">Pets</a></li>
				<li><a href="<?php echo get_permalink(173); ?>">Uncategorized</a></li>
			</menu><!-- menu2 -->
			</li>
			<li><a href="<?php echo get_permalink(184); ?>">Movies</a></li>
	</menu><!-- menu1 -->
	</li>
	</menu><!-- booksandmovies -->

Anyone? I can't find information for how to make this work right.
