Ok, got the script working with EMBEDs (just for the notes):
<script type="text/javascript">
// function to show line of any selected country
function showLine(id)
{
svgDocument = document.embeds["svg_object"].getSVGDocument();
delta = svgDocument.getElementById("g" + id);
delta.setAttribute("visibility", "visible"); //add
behaviour
}
</script>
Still wondering about the OBJECT/EMBED issue. And the script does not work with
the OBJECT...
