Question

Добрый вечер! Подскажите, что нужно сделать чтобы код заработал в IE и опере. В ff все работает отлично.

Пробовал через appendChild, но переставало работать вообще везде ;).

<script type="text/javascript" language="javascript">
function changeView(name){

var arSelect = new Array();
arSelect[123] = '<select name="reg[subkat]" id="123"><option value="" /><option value="124"/>subkat1<option value="125"/>subkat2</select>';
arSelect[126] = '<select name="reg[subkat]" id="126"><option value="" /><option value="127"/>subkat1<option value="128"/>subkat2<option value="129"/>subkat3</select>';
if (name == '')
{
arSelect[name] = '';
}
var sub = document.getElementById('sub');
sub.innerHTML = arSelect[name];
}
</script>
...
<select name="reg[kat]" onchange="changeView(this.value)">
<option value="" />
<option value="123"/>kat1
<option value="126"/>kat2
</select>
<span id="sub"></span>
