A DOM script is dumb, like an X3D script that only uses directouts. The DOM script doesn't declare fields, but can act like a directout with get and assignments. If you want to track events caused by the dom script then you must watch or observe, or set a listener or whatever, at the attribute actually changed by the script. If we can understand this then we can deal with the differences. When we see mutation finders, watch and observe stuff, then we see that DOM is just getting around to designing some interfaces that allow an x3d-like event system. <br><br>For me, this makes me appreciate scripts that don't send events until complete and routes that make it easy to monitor and process updates. <br><br>All Best, <br>Joe<br><br><blockquote style="padding-left: 5px; margin-left: 0px; border-left: #0000ff 2px solid; font-weight: normal; font-style: normal; text-decoration: none; font-size: 10pt; font-family: arial,sans-serif; color: black;">-----Original Message-----
