Callback without ajax or iframe (Pure Code)

I have a conditional function in my controller for what it has been posted from the view. Therefore, I want to send the respond or a callback to the view when the data is submitted.

For some reason, I don't want to use ajax or iframe to handle this callback.

I am expecting a pure javascript combined with php to do this:

The sketch might be like this: 

<script>
    var callbackFromController = <?php echo $callbackFromController;?>

    if(callbackFromController == "Love")
        {
            alert("This is Love"); 
        }
    else if(callbackFromController == "Wealth")
        {
            alert("This is Wealth"); 
        }
    else if(callbackFromController == "Healt")
        {
            alert("This is Healt"); 
        }
    else 
        {
            alert("This is Life"); 
        }

</script>

But I want to get the $callbackFromController as soon as the button is submitted (Like ajax success respond)

Once again, I don't want to use ajax or iframe for this one.

The reason I don't want to use ajax is I don't want to pass the url as well as the data in the ajax post.

[Updated]

Based on the answer I've got from this question, it is said that I have to use either ajax or iframe.

If I have to use ajax, can I do this without passing the url and/or data post or get?

PHP writes the value out before the page is served to the browser.

If that's the case, then PHP can not write it out after a button has been clicked on the page, unless you are reloading the page.

...an alternative might be to dynamically create a link to a new script page (which is actually a .php page, but served with an application/javascript MIME type), which contains both your script logic and your PHP writing...

This is a horrible solution, but it's technically possible; you just have to do the wrong thing at every level (client, apache web-server and php web-app) layer.

You are unable to interact with PHP without reloading the page or using AJAX request or iframe, as you suggested.
