Newbie ask:

Did I miss something?

Loaded scripts

Code

Ext.onReady(function() {
    Ext.Ajax.request({
        method: 'GET',
        url: '<?php $template_url."/raw-post.php" ?>',
        params: { Xc : 0, Xp : <?php echo '84'; ?> },
        success: function( result, request ){
            Ext.get('test').dom.innerHTML = result.responseText;
        }
    });
});
