Top menu Breadcrumbs disappear when an anchor is selected

[goutnet]

Hi,

It seems the top breadcrumbs disappear when I select a section, here is an example, in a test page I created 2 sections:

This is displayed correctly in the URL does not have a #my_section in the end. But if A section is selected, this happens:

As you can see, the upper section (breadcrumbs and Edit) is gone :'(

Hi.

When you click a section in the TOC, the content is scrolled to where the section is. I think you can scroll up to the top and breadcrumbs are there. If you can't scroll I need to investigate it.

Unfortunately, we can not scroll up ^^;

That's weird, it never happened to me. Did you clean install Dokuwiki? Are you using some plugins?

Yes we are using quite a few plugins, I can investigate that too, but I am not sure I have the bandwidth to do a clean install anytime soon ^^;

If you can list your plugins I'll test them on my computer. Or you can test by disabling all plugins and see if the bug still occurs.

Hi,

here is the list of plugins we have installed on our production environment:

I am not sure if that would help ^̂^;

let us know :)

That's quite a lot! I've installed all those plugins but sadly I couldn't reproduce the situation…Maybe depends on the plugin settings?

Is the sidebar shown when breadcrumbs are displayed correctly? If not, user custom styles might be the cause.

I’ll continue to investigate to reproduce the bug but it is better to test on your site, by disabling all the plugins or disabling user custom styles if possible.

Hi, thanks for the hard work, I am thinking it might be in js code:

Here are steps to reproduce it at least on my end:

1. Create a page with several sections (the page itself must be longer that can be displayed in one page)
2. Edit one of the sections (e.g. using fastwiki)
3. save
4. you will be redirected to http://wiki/your/page#anchor (anchor being the section editted)

From there the top header is hidden.

If you directly connect onto the page itself: http://wiki/your/page#anchor (no editting required) the same behavior happens too.

I think the (maybe) impactful plugins would be markdown and fastwiki, but I doubt it.

Also, in the script.js:

/* DOKUWIKI:include js/readthedokus.js */                                                                                                                                                                                   

var dokus;                                                                                                                                                                                                                  
document.addEventListener("DOMContentLoaded", function() {                                                                                                                                                                  
        if (document.body.id === "dokuwiki__top") {                                                                                                                                                                         
                dokus = new ReadtheDokus();                                                                                                                                                                                 
                dokus.run();                                                                                                                                                                                                
        }                                                                                                                                                                                                                   
}); 

If I disabled the code here, the problem does not show up (still investigating).

[my17560]

The function called _jumpToAnchor() is called to jump to the section. That must be conflicting with something. Are there any errors shown in Developer Mode's console?

[goutnet]

Might be related, but I do have an error here:

Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.
(anonymous) @ js.php?t=readthedokus&tseed=f5699ab5b0f63b30408d6a692b33949e:9

on the following line

document.write('<style type="text/css" media="screen"><!--/*--><![CDATA[/*><!--*/ .folded.hidden { display: none; } .folder .indicator { visibility: visible; } /*]]>*/--></style>');

[goutnet]

From a grep in the code, that was in the folded plugin, but even after disabling it, while the message is gone, the header problem still remains.

[goutnet]

Looking in the debugger, and adding a breakpoint in the _jumpToAnchor method, I see the following line seems to change the header height to 0:

        location.href = hash;

Seems after executing that line the header is gone.

[goutnet]

For information, for now I just comment this line to fix this issue … (which works) ^^;

https://github.com/my17560/dokuwiki-template-readthedokus/blob/main/js/readthedokus.js#L535

(clicking on the TOC still brings the section, and linking to the section too)…

With that said, I still have the problem after editting a section and cancel/save, seems a similar code must be somewhere too.

[goutnet]

I think I found the issue (even though the cause is not clear):

if my footer.html I had a code like this:

<div id="page_disclaimer">
     <div id="page_disclaimer_content" class="group">
    My Disclaimer here
     </div>
<div/>

in the header.html I had a style css to add a padding-top of 1.6em to the inner div. Removing that or replacing it with a margin-top instead fixes the issue.

So, I am going with this :)
