HTML input Javascript to detect enter/return key not working

Question

I have been calling this script from a Windows batch file, to input data into a variable.

It works, but I have two problems.

It does not detect the return/enter keypress in Chrome. I only have a return key, but I presume Enter returns the same code.
When the input box appears is there a way to make it active, with the cursor already in the box?

<!-- :
::
@echo off
setlocal EnableDelayedExpansion

if "%~1" equ "/?" (
    echo Creates an input value window and output
    echo   the result to console or assign it to variable
    echo   if variable name is passed
    (echo()
    echo Usage:
    (echo()
    echo %~0nx [storeInputTo]
)
for /f "tokens=* delims=" %%p in ('mshta.exe "%~f0"') do (
    set "input=%%p"
)


if "%~1" equ "" (
    echo "%input%"
    endlocal
) else (
    endlocal & (
        set "%~1=%input%"
    )
)
exit /b
-->

<html>
<head><title>Enter Album Name</title></head>
<body>

    <script language='javascript' >
        window.resizeTo(650,250);
        window.moveTo((screen.width/2)-325, (screen.height/2)-125);
        function enterPressed(e){
                if (e.keyCode == 13) {
                    pipePass();
                }
        }
        function pipePass() {
            var pass=document.getElementById('input').value;
            var fso= new ActiveXObject('Scripting.FileSystemObject').GetStandardStream(1);
            close(fso.Write(pass));

        }
    </script>

    <input type="text" id="input" value="" size="50">
    <hr>
    <button onclick='pipePass()'>Submit</button>

</body>
</html>

Ideally, I would like:

Return/Enter to be detected instead of having to click Submit.
Cursor is to be active in input box so no need to click before typing.

Please do not use the comparison operator `equ` for a string comparison in a Windows batch file. It is possible, but it is better to use the comparison operator `==` for a string comparison. See my answer on [Symbol equivalent to NEQ, LSS, GTR, etc. in Windows batch files](https://stackoverflow.com/a/47386323/3074564) for a detailed description about the difference between `==` and `equ` on comparing two strings. — Mofi, Jul 09 '23 at 16:21

ActiveXObject is not supported by any browsers except IE

I suggest you set up a simple web server on your box and use a standard form submit.

Since a single field will submit on enter, you can then have

<form action="yourserverprocess">
  <input type="text" id="title" name="title" value="" />
  <input type="submit" value="Optional Submit button"/>
</form>
<script>
  window.addEventListener("DOMContentLoaded", () => {
    const field = document.getElementById("title")
    field.select();
    field.focus();
  });
</script>
