Oops, that isn't legitimate... I was trying to remove the Mustache code and simplify it.

I saw some code which uses statements like this... <div class="img01" style="background-image:url(/utilities/imageurl.php?no=1651)"></div> Is this commonly done?

As Dsonesuk says above, study the examples. Are you using GET or POST?

One thing that you might be confusing is that client-side session storage is not the same as server-side session storage. Server-side session storage is secure, while Javascript sessionStorage is just a variation of localStorage which is a replacement for old-fashioned cookies. Server: https://www.w3schools.com/asp/asp_sessions.asp Client: https://www.w3schools.com/html/html5_webstorage.asp

Hmmm... why do you expect server-side code to be able to see client-side Javascript variables? Server-side code runs and then the browser loads the page and then client-side Javascript runs.

What are you using as server-side code?

I get a 404 error on that page so I suspect the site designers are changing things. You might start here... https://www.w3schools.com/howto/howto_css_parallax.asp

If your pages are properly marked as copyrighted material you could try mailing warning letters to the offenders. Javascript can be turned off so you can't expect Javascript to protect anything.

Sorry, Javascript can't open Notepad or run any other executable. https://www.w3schools.com/jsref/met_win_open.asp

So if you can't even log into the server to administer your website then you obviously need to contact the hosting support.

What JustSomeGuy says is also true if you use element.addEventListener(). The function name is used without the argument parens.

It seem like SEO is mostly voodoo. https://www.seroundtable.com/google-absolute-vs-relative-urls-26001.html

Learn about relative paths... https://www.w3schools.com/htmL/html_filepaths.asp Also another common problem is that when testing on a Windows pc the paths and file names are not case-sensitive -- but then you transfer the file to a Linux server which is case-sensitive.

File upload to the web root folder?

If you're using Windows 10 you can install Linux and use Bash scripts. https://docs.microsoft.com/en-us/windows/wsl/install-win10
