Hmm, how about...a simple link:
Code:
<a href="your link" target="your iframe" onclick="focusIframe();">Hello</a>
Then some JS (put this in the <head> or <body> area):
Code:
<script type="text/javascript">
function focusIframe( ) {
var theElement = document.getElementById( "your iframe id" );
if ( document.all ) {
// Internet Explorer
theElement.document.body.focus( );
} else {
// Firefox
theElement.contentDocument.body.focus( );
}
}
</script>
...with some credit due to the FF/IE differences here.
Just remember to set the id="your iframe id" attribute.
That might work, though it's pure speculation...
