In the first way, is "Unexpected Exception" the entire text of the
error? Assuming this is in Firefox, there's usually more detail than
that. If there's not, then try splitting that line across multiple
lines of code to see which step causes the exception.
I did a little test in Firefox to see if I could get your code working
(just for the first method). I changed:
var myWidth = svgdoc.ElementById('tooltipBoxLabel').getBBox().width;
to:
var myWidth = document.getElementById('tooltipBoxLabel').getBBox().width;
And I get the error:
uncaught exception: [Exception... "Component returned failure code:
0x80004005 (NS_ERROR_FAILURE) [nsIDOMSVGLocatable.getBBox]" nsresult:
"0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file:///... ::
init :: line 22" data: no]
This is an internal error in Firefox and I think it might mean that
getBBox() isn't available in their implementation, even though the
function is there and you can call it. Someone please correct me if
I'm wrong.
