global variables in requireJS

[felito]

This is a simple demo about my problem.

 

I need to access the id_user in main.js file. My question is, how to avoid global variables in this situation? It is bad practice use global variables for this purpose?

 

main.js

require({
    paths : {
        jQuery : 'http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min'
    }
});

require([ 'jQuery' ], function() {
       alert(id_user);
    });

 

index.php

 

<script data-main="js/main" src="js/require.js"></script>

<script type="text/javascript">
function users() {
    id_user = <?php echo $id; ?>
}

users();
</script>
