What's the easiest way to filter a Dropdown listbox based on the value of another listbox without having to submit the form?  Is there an easier way than using div statements?

Example:

Listbox A is a list of stores. "S1", "S2", etc...
Listbox B is a list of products for a store "S1P1", "S1P2", "S2P1", S2P2", etc....

I want to retrieve all of the products when the page is accessed but I want to filter the list based on which store is selected in Listbox A.

Thanks

<script>
function setVal(theSel) {
   if (theSel.selectedIndex < 1) return;
   storeSel = theSel.form.store;
   prods = theSel.options[theSel.selectedIndex].value.split('|')
   for (i=0;i<prods.length;i++) {
      storeSel.options[i+1] = new Option(prods[i],prods[i]);
   }
}
</script>
<form>
<select onChange="setVal(this)"><
<option value="">Select store
<option value="P1|P2">Store 1</option>
<option value="P2|P3">Store 2</option>
</select>
<selectname="store">
<option value="">Select Product
<option>__________________</option>
<option>__________________</option>
</select>
</form>

You can also store the values in arrays and access them directly without using the split method
