Dear Ann,
I have tested your "index.html" file in a recent version of NetBeans and
reproduced your problem. I regret having to say that you have found a
bug in the "NetBeans Connector". I have filled issue #6601 (see [1]) for
you.
In order to communicate with the Chrome web browser, NetBeans uses a
"browser plugin" called the "NetBeans Connector" that is published in
the Chrome Web Store (see [2]).
As you can see, this plugin has not been updated since 2015, two years
before NetBeans was donated by Oracle to the Apache Software Foundation.
Since then, web browsers have evolved rapidly, and I suspect this
"browser plugin" from 2015 doesn't work in recent versions of Chrome. We
must review the source code of this "browser plugin" ([3]).
As an immediate aid, you may want to explore the so called "Chrome
DevTools" (see https://developer.chrome.com/docs/devtools/ for more
details and videos), that are installed by default and that allow you to
inspect and modify the HTML DOM and to debug JavaScript within the
browser itself. Note that modifying the HTML DOM in the browser itself
does not allow you to save changes to disk.
Finally let me tell you, Ann, that I think the entire NetBeans Team
envies your curiosity and desire to learn. Let us know if we can be of
further help.
Our best wishes,
Antonio

For about 5 years, I have not tried though.
I want to find out if I can use javascript, html, css to create a
browser program to process a whole bunch of images in an sophisticated
directory structure. When I try to run Netbeans (8 or 12) with the
Chrome connector, I get an error dialog. If / I double click on the
index.html I get an error dialog. As shown below and also attached./

/The program runs. What can I do to gert rid of this?/
