Dobbelt drop down

Hej med jer.

Jeg vil gerne benytte nedenstående script, men jeg vil gerne have, at scriptet fungerer uden en "go" knap.

Det skal fungere således, at når 2. dropdown vælges, skal der hoppes til pågældende side.

Er der nogen der kan hjælpe?

Scriptet ser således ud:


<CENTER>

<form name="doublecombo">

<p><select name="example" size="1" onChange="redirect(this.options.selectedIndex)">

<option>Webmaster Sites</option>

<option>News Sites</option>

<option>Search Engines</option>

</select>

<select name="stage2" size="1">

<option value="http://wsabstract.com">Website Abstraction</option>

<option value="http://www.free-backgrounds.com">Free-backgrounds.com</option>

<option value="http://www.dynamicdrive.com">Dynamic Drive</option>

<option value="http://www.reallybig.com">Reallybig</option>

</select>

<input type="button" name="test" value="Go!"

onClick="go()">

</p>



<script>
