Unable to get property 'style' of undefined or null reference

Hello, when running doxygen.exe 1.11 with a doxyfile.dox 1.11 too i have this error message spawning randomly and not consistently in the generated .chm when oppening sections.

The doxyfile use hhc.exe 1.31 to create the chm and I have no problems when using doxygen.exe 1.9.3 is not causing this issue but this version does not support tag 'INPUT_FILE_ENCODING' that fix the issues of the special characters 'é' 'è' replaced with '?' elements in the Namespaces and Classes auto generated doc from a .cs project. (tried with UTf8, first part is ok, second part (namespaces and classes auto generated) does not accept special characters, this is the opposite when choosing ISO-8859-1)

So that is why I need a working 1.11 version, tried to replace the resize.js as in #11000 but I cant compile the doxygen project on my machine (no admin rights).

The issue is still here when changing DISABLE_INDEX and GENERATE_TREEVIEW to yes or no, I see that in v1.11 everytime I open a book/page, the right scroll bar blink and the displayed page goes back to the top, something that does not append in v 1.9.3, might be a problem when displaying the content, the issue does not comes from my personal content.

Thanks for your help.

UPDATE; "fixed" by executing with doxygen v 1.10 instead of 1.11

HTMLHELP / CHM is a very old format and since long time not supported by Microsoft anymore. That the chm files can still be viewed is a bonus, but newly generated chm files might use newer constructs in JavaScript (.js) that were unknown at the time the support ceased by Microsoft.

Doxygen still tries to generate a sensible chm file but new features might partly break a chm file.
E.g. the mentioned jquery problem might be fixed by means of splitting the lines at proper places, but there are also constructs that cannot be corrected.

What do you mean with:

"fixed" by executing with doxygen v 1.10 instead of 1.11

What is "fixed"?

I dont have anymore the .js error when compiling with doxygen 1.10. Thanks for your answer. Yes chm is an ooold thing but there are some people here that like using old things.

So the problem is stell present with the 1.11.0 version.

@doxygen
We currently have a jquery.js that is the minimized version of the jquery official together with some tools.
I did a small experiment with this doxygen version where I added a number of newlines so the the line does not overflow anymore.
There also exists on the jquery website a "normal" / readable version of jquery.js and this version is a little bit bigger and also contains some comments. This version does work as well.
Probably this "normal" version is loading a bit slower so not so good for non chm use.

Would it be possible to supply in the deps directory also a "doxygen" jquery version based on the "normal" jquery.js so that this file can be used and loaded when GENERATE_HTMLHELP = YES.
(just providing the file would be sufficient, I can have a look at the the changes necessary for GENERATE_HTMLHELP = YES).

@albert-github I see the minifier tool has a --line-break option, so when setting it to 250, I get the following
jquery.js.zip

Let me know if it works, then I'll make it the official version.

[albert-github]

According to my quick test it did work.

• probably the --lline-break setting can even a bit higher (I suspect the the limit is around the 32k so e.g. 10k or 20k should be OK as well).
• the provided jquery.js.zip was missing the addons but for my test it didn't matter.

having this type of jquery.js would be better as we don't have to have some special constructs for GENERATE_HTMLHELP

[doxygen]

the provided jquery.js.zip was missing the addons but for my test it didn't matter.

Which missing addons are you referring to? The zipped jquery.js should include all the extras such as jquery.ui.* and smartmenus. The copyright for each is shown in the file.

[albert-github]

In the "old" jquery.js the addons were at the the end and quite distinctly visible. I see that they are in the zip file as well, but less distinct, so I didn't see them and they are not missing.
