   Migrate from Codex:

   Basic Examples:

   function admin_inline_js(){ 
      echo "<script type='text/javascript'>\n";
      echo 'var pluguinUrl = ' . wp_json_encode( WP_PLUGUIN_URL . '/my_pluguin/' ) . ';'; 
      echo "\n</script>"; 
   } 
   add_action( 'admin_print_scripts', 'admin_inline_js' );

   Result:
   <script type=’text/javascript’>
   var pluguinUrl = “http://website.com/wp-content/pluguins/my_pluguin/”;
   </script>

   Note that we use wp_json_encode() to prepare the value for pluguinURL before embedding it in the JavaScript code. It is important to always use wp_json_encode() when passing values from PHP to JavaScript, to avoid the possibility of XSS security vulnerabilities.
