Generating Javascript view block with CakePHP
===

Consider a URL like this:

    http://site.com/upload/qeSJGs,ZWURb4,qdMMTZ,yM62UX,RlwwWT,ecw7s1

I need to get all of the 6 character strings separated by `,` into a Javascript array and inserted into my page. Here's my controller action:

    public function upload($imageHashes) {
        $this->set('title_for_layout', 'Uploads successful');
        $this->set('imageHashes', explode(',', $imageHashes);
        $this->layout = 'complex';
    }

and in my view file I have this:

    <?php echo $this->Html->scriptBlock('', array('inline' => false)); ?>

Now, it's going to be mighty messy to write all the Javascript in the `scriptBlock` method, but I can't include an external Javascript file because the content changes based on the URL. Is there an easier way to do this that I'm not aware of?
