Embedding php in javascripts

I tried to inject some PHP into a javscript function that is called from onChange in a drop down list. the javascript function is in the .js file, I can force the DDL to call the function, however I cannot make this function work with php ... in the end I am going to use the value selected in DDL to access the DB and fill in other fields from there, right now I'm trying to get it to work with php:

    function controllerType(){

       alert('outside php');
       <?php
       $message = "inside php";
       echo "alert('$message');";
       ?>

     }

The function prints the first warning, but not the warning called in php.

Your web server is probably not looking for PHP code in the .jsdefault files . You will need to say that you need to look for PHP in these files or change the file extension to .php.

, - Apache, .htaccess:

AddHandler application/x-httpd-php .js

function controllerType() {
    alert('outside php');
    alert('<?php echo $message; ?>');
}

It looks like you are trying to run PHP code at runtime in a browser. PHP is a server-side language and you cannot just use it in a javascript file as you try.

You need the javascript function to output the value from the drop-down list to the PHP page through an HTML form or through AJAX.

Forgive me if I misunderstood you.
