Bug 10151 – ghostmap XHTML + SVG fails due to javascript undefined exception

• Status: RESOLVED
• Resolution: FIXED
• Component: SVG

I'm not sure from looking at the JS console as to why this SVG + XHTML document is failing.  The error shown in the console does not make any sense.

This would be a cool demo of SVG + XHTML if we could make it work.

Actually there does not seem many problems. The main one is that the js contains document.URL, which AFAIK is a not supported IE extension. Note that FF must support it since this svg just works there. When I replaced it in the <script>
with window.location.href (in 2 places) at least it rendered fine. After that
the only problem is that the drawing area is unclipped, but I bet there is
a seperate bug on that. Maybe someone with authority/experience can say
how to handle document.URL, I have no idea how much it is used in real-life
web pages.
Cheers,

Rob.

Forget my earlier comment, document.URL *is* supported. Just in this
particular testcase it evaluates to 'undefined'. Maybe something to
do with being of xhtml+svg kind, further investigating...
Cheers,

Rob.

The problem in the end was not very svg specific. document.URL just only worked
for html documents, this patch should fix that and the testcase. I also included
the one changed result. Let me know if this requires an extra testcase, I don't
think so since HTMLDocument04.xhtml tests it.
Cheers,
