updating href when onclick or onchange in drop down box/menu selection

chineerat

hi!
I would like to know if there is a way to update a href link (without page reload) when a selection is made in a drop down box/menu?

for example:
<?php
echo "<select name='subcat' onchange('function to append noticia[x] to href')><option value=''>Select caterogry</option>";
while (query=true){
echo "<option selected value='$noticia[x]>$noticia[y]</option>"."<BR>";}

?>
<a href= localhost/?subcat=noticia[x] /a>

note: the page is not to be reloaded nor are the drop down boxes to be reset when selection is made in menu

thanks in advance

<script type="text/javascript">
function one() {
	alert('one');
}
function two() {
	alert('two');
}
function setHref(o) {
	var val	= o.value;
	var d	= document;
	var a	= d.getElementById('lnk');

if (parseInt(val) == 1)
	a.href = 'javascript:one()';
else if (parseInt(val) == 2)
	a.href = 'javascript:two()';
}
</script>
</head>
<body onload="">
<div style="margin: 12px;">
<select onchange="setHref(this);">
	<option value="0">Please choose...</option>
	<option>1</option>
	<option>2</option>
</select>
<br/>
<a id="lnk" href="not set">Not set</a>

Or, if you don't want to call js functions

function setHref(o) {
	var val	= o.value;
	var d	= document;
	var a	= d.getElementById('lnk');

a.href = val;
}
