9 years ago I ran into this problem too when trying to upgrade from jQuery 1.5 to 1.6.1 in
my svgweb application.
The short solution:
It was found that moving all non-svgweb script tags out of the <head> section
of the page and putting them at the very bottom solved this problem.
Detailed explanation:
The error that was reported in the original post was thrown from line 2274 of
svg-uncompressed.js. This is where svgweb tries to get the value of the
'onsvgload' attribute from the HTML body tag. This was failing because the
statement
>> body = document.getElementsByTagName('body')[0]
was returning undefined.
Through a lot of debugging using Visual Studio, it became apparent that for
some reason (the exact cause still is still unknown) Internet Explorer did not
parse the HTML document fully when jQuery 1.6(.1) was used instead of jQuery
1.5(.1|2). This meant that when the empty script that svgweb adds to the end
of the file to test the DOM's ready-state was 'finished' loading, the DOM
didn't exist or wasn't parsed for whatever reason. The result is that the the
body of the document was undefined.
This suggested that the process of loading jQuery 1.6 immediately after svgweb
was somehow corrupting the process of parsing the entirety of the HTML file. A
point to note is that during testing, when loading just svgweb or just jQuery
Internet Explorer had no issues parsing the entire document. Somehow, the
combination of svgweb and jQuery 1.6(.1) caused it to fail.
All this suggested that it was not a problem that could be fixed through syntax
corrections (at least without far more in-depth knowledge of both projects).
So, to try and give Internet Explorer a chance to parse the HTML before the
scripts were loaded (and potentially corrupt the loading process) the scripts
were moved to the end of the HTML file which solved the problem.
From what I have seen in dealing with this issue, I would lean towards this
being a problem with the changes made to jQuery in 1.5.2->1.6 since that is
when the error arose. It is my best-guess that it is not a problem with
svgweb, but I could be wrong.
Note: I had my svg included directly in the HTML with a <script
type="image/svg+xml"> tag. I have not tested things with the <embed> method of
including SVG code.Original comment by david.qu...@gmail.com on 22 Jun 2011 at 7:14
