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:

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...

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.

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.

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.

As Ingolme says, you have the decryption code and obviously Javascript is the only reasonable language choice. The problem is choosing passwords and detecting success. Now, as an example, if you know that the successful decryption will result in a phrase that contains one of the English words; "the", "and", or "is" then an "appropriate test" you might use;

test = toLowerCase(test);

if(test.indexOf('the') != -1 || test.indexOf('and') != -1 || test.indexOf('is') != -1){
    alert(test);
}

or this might be better...

var t = toLowerCase(test);
if(t.indexOf(' the ') != -1 || t.indexOf(' and ') != -1 || t.indexOf(' is ') != -1){
   alert(test);
}

1. You need to have some idea what was encrypted -- and an appropriate test that will detect that output.

2. You need a list of passwords such as Popular Passwords 2017

3. You need to write a script that will attempt each password in the list and test the result.

I think this would be a good beginner's project for you.

Sure, if the password that was used was weak and you have a dictionary of all probable passwords.

The file "form-to-email.php" does not exist.

We have no idea what is available in your country. You will have to search.

W3Schools does not have an Android or a Java tutorial. Do you know Java?
