Ok, if I understand you correctly, implementing the mechanism akin to
the latex one, setting a new variable `org-html-prefer-user-labels` would
change the relevant exported HTML for the following piece of org:
----------------------
#+NAME: test_fun
#+BEGIN_SRC js :exports code
function test_fun() {
}
#+END_SRC
Link to [[test_fun]]
#+CAPTION: Caption of Another Test Fun
#+NAME: another_test_fun
#+BEGIN_SRC js
function another_test_fun() {
}
#+END_SRC
Link to [[another_test_fun]]
-----------------------
from
#+BEGIN_EXAMPLE html
<pre class="src src-js" id="orgsrcblock1">
...
</pre>
<pre class="src src-js" id="orgsrcblock2">
...
</pre>
Link to <a href="#orgsrcblock1">1</a>
Link to <a href="#orgsrcblock2">1</a>
#+END_EXAMPLE
to
#+BEGIN_EXAMPLE html
<pre class="src src-js" id="test_fun">
...
</pre>
<pre class="src src-js" id="another_test_fun">
...
</pre>
Link to <a href="#test_fun">1</a>
Link to <a href="#another_test_fun">1</a>
#+END_EXAMPLE
Looking at `org-html-link`, `org-export-get-reference` is only called
to get the _internal_ reference. That works perfectly fine already, and I am
quite happy with the way org mode generates labels/ids for the exported
code. That should, however, have no influence of the link description
(called `desc` in the code in `org-html-link`), which is the thing
that I actually want to change?
In summary, my exported output is supposed to look like that:
#+BEGIN_EXAMPLE html
<pre class="src src-js" id="orgsrcblock1">
...
</pre>
<pre class="src src-js" id="orgsrcblock2">
...
</pre>
Link to <a href="#orgsrcblock1">test_fun</a>
Link to <a href="#orgsrcblock2">another_test_fun</a>
#+END_EXAMPLE
