Andre and David: Thanks for your responses. I think my problem has to do with my lack of understanding of the SVG DOM and event handling. Here's my example that I'm wresting with:
A web page 3.html contains 3.svg in an iframe: <html> <head> <title>TestBed</title> </head> <body> <iframe id="map" width="400" height="400" src="3.svg" type="image/svg+xml"></iframe> <textarea id="output" rows="10" cols="40" > </textarea> </body> </html> 3.svg looks like: <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd";> <svg width="210pt" height="272pt" viewBox = "-1 -1 209 271" xmlns="http://www.w3.org/2000/svg"; > <script type="text/ecmascript"> <![CDATA[ function getSummary(evt) { var element = evt.target; var myid = element.getAttributeNS(null,'id'); var buf = "The ID is " + myid + "."; // textarea in html var foo = top.document.getElementById("output"); foo.value = buf; } ]]> </script> <g id="node1" class="node" onclick="getSummary(evt);" > <title>node1</title> <polygon id="poly" fill="#ff0000" stroke="#ff0000" points="59,4 5,4 5,40 59,40 59,4" /> <text id="text" text-anchor="middle" font-family="arial" font-size="8px;" x="32" y="23"> Node 1 </text> </g> </svg> So what happens is that when I click on the polygon I get the output "The ID is poly." When I click on the text node 1, I get "The ID is text." Makes sense, but I what I really want is the id of the surrounding group (id="node1") to be returned. Is there a way to do that? BTW, I'm using Firefox 1.5rc2 without a plugin if that makes a difference.
