call javascript when user logs in

[spacexplorer]

in

custom/modules/Users/logic_hooks.php

I have the following:

 $hook_array['after_login'][] = Array(1, 'call login javascript', 'custom/modules/ExternalHooks/callJavascript.php','myClass', 'phpFunctionToCall'); 
  

and in the callJavascript.php I can have

 function phpFunctionToCall(&$bean, $event, $arguments)
    {
//die("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx $bean->assigned_user_id");    
    } 
  

I want to call a javascript with the user_id as param - the reason is that I am testing embedding sugar in an adobe-air app that will talk to sugar through javascript
