Node request HTML accessing global variables

Hey I'm trying to access global variables from the result of a HTML request in node. I can currently access the nodes using the cheerio module however I'm stumped as to how I can access a global page variable ?

request(options, function(error, response, html) {

        if (!error && response.statusCode == 200) {

                var productData = {};

                // access html with JQUERY
                var $ = cheerio.load(html);

                // is it possible to access global 
    // page variables here ?
    
        }
}
