<select id="userid[]" name="userid[]" onchange="changeuserinfo();">
and in the javascript use
FormObject=document.forms['name of form'];
SelectObject=FormObject.elements['userid[]'];
you can then loop through the array SelectObject.options[], checking the
'selected' property to see which items have been selected
SelectionCount=0;
for(n=0;n<SelectObject.options.length;n++)
{
if(SelectObject.options[n].selected)
{
// option selected
SelectionCount++;
}
else
{
// option not selected
}
}
The SelectObject.selectedindex property only shows the first selected
element.
