Hi Edith,
The problem is with the window object.
Most viewers return the window object of the browser, some (incl. the Adobe
viewer)
return the window object of the SVG viewer, which doesn't know the .open()
method.
What you could do is test if "window.open" is available and if not, use an
alternative. You
could use a try and catch construct for that purpose. Something like:
var xlinkNS = "http://www.w3.org/1999/xlink";;
var someLinks = new
Array("http://www.w3.org","http://www.svg.org/","http://
www.svgx.org","http://www.carto.net","http://www.svgopen.org";);
function openWindow(url) {
var index = Math.round(Math.random()*5);
try {
//case browsers with native SVG support
(Opera9, Firefox, Apple
Webkit)
window.open(someLinks[index]);
}
catch (er) {
//case ASV, where window defaults to the ASV
window object
browserEval("window.open('"+someLinks[index]+"')");
}
}
function alternativeOpenWindow(evt,url) {
var index = Math.round(Math.random()*5);
evt.target.parentNode.setAttributeNS(xlinkNS,"href",someLinks[index]);
}
I'd prefer the second method, though, since it works around some popup blockers.
Here is the example online:

Hope this helps,
Andreas
