Opera Select selected index
Hi All,
I have a document that uses the following javascript code to let me know what the currently selected index of a select box is.
This works fine in IE though it doesn't work in Opera - I have had a look around and can't find a replacement or workaround for this.PHP Code:document.<form_name>.<select_name>.selectedIndex
Does anyone know of any solutions?
Many Thanks.

I can't post a link as it isn't on the internet.
The page is the top part of a two row frame.
Here is the code:
Hope this makes it clearer.
<script>
function nextsite() {
maxposition = document.browselinks.browseoptions.length;
curposition = document.browselinks.browseoptions.selectedIndex;
if (curposition!=(maxposition-1)) {
curposition++;
document.browselinks.browseoptions.selectedIndex = curposition;
//parent.content.location.href=document.browselinks.browseoptions.selectedIndex.value;
parent.content.location.href=document.browselinks.browseoptions.options[document.browselinks.browseoptions.selectedIndex].value;
}
}
function prevsite() {
curposition = document.browselinks.browseoptions.selectedIndex;
if (curposition>0) {
curposition=curposition-1;
document.browselinks.browseoptions.selectedIndex = curposition;
parent.content.location.href=document.browselinks.browseoptions.selectedIndex.value;
}
}
</script>
</head>
<body>
<table>
<tr>
<td valign="top">
<a href="#" onClick="prevsite();">Previous Site</a>
</td>
<td>
<form name="browselinks" action="">
<select name="browseoptions" onChange="parent.content.location.href = this.options[this.selectedIndex].value;">
<option selected></option>
<option value="http://link1.com">This is link1</option>
<option value="http://link2.com">This is link2</option>
<option value="http://link3.com">This is link3</option>
</select>
</form>
</td>
<td valign="top">
<a href="#" onClick="nextsite();">Next Site</a>
<!-- document.browselinks.browseoptions.selectedIndex -->
</td>
<td>
<script>
var value1=document.browselinks.browseoptions.length;
var value2 = document.browselinks.browseoptions.selectedIndex;
document.write(value1);
document.write(value2);
//This is a test to see if the selected index works in Opera
</script>
</td>
</tr>
</table>

The transfer line (parent.content.location.href=...) in prevsite() is wrong, it should be the same as the one in nextsite().

That bit works fine - it is the code:
document.<form_name>.<select_name>.selectedIndex
that doesn't work in Opera.

The bit here:
In Opera I generally get undefined for value2 - thought in IE it will say 0<script>
var value1=document.browselinks.browseoptions.length;
var value2 = document.browselinks.browseoptions.selectedIndex;
document.write(value1);
document.write(value2);
//This is a test to see if the selected index works in Opera
</script>
