Node.js Web Scraping with Jsdom - node.js

Question

I would like to scrape the http://www.euromillones.com.es/ website to get the last winning 5 numbers and two stars. It can be seen on the left column of the website. I've been reading tutorials, but I am not capable of achieving this.
This is the code I wrote so far:
app.get('/winnernumbers', function(req, res){
//Tell the request that we want to fetch youtube.com, send the results to a callback function
request({uri: 'http://www.euromillones.com.es/ '}, function(err, response, body){
var self = this;
self.items = new Array();//I feel like I want to save my results in an array
//Just a basic error check
if(err && response.statusCode !== 200){console.log('Request error.');}
//Send the body param as the HTML code we will parse in jsdom
//also tell jsdom to attach jQuery in the scripts and loaded from jQuery.com
jsdom.env({
html: body,
scripts: ['http://code.jquery.com/jquery-1.6.min.js ']
}, function(err, window){
//Use jQuery just as in a regular HTML page
var $ = window.jQuery;
res.send($('title').text());
});
});
});
I am getting the following error:
Must pass a "created", "loaded", "done" option or a callback to jsdom.env.

It looks to me that you've just used a combination of arguments that jsdom does not know how to handle. The documentation shows this signature:
jsdom.env(string, [scripts], [config], callback);
The two middle arguments are optional but you'll note that all possible combinations here start with a string and end with a callback. The documentation mentions one more way to call jsdom.env, and that's by passing a single config argument. What you are doing amounts to:
jsdom.env(config, callback);
which does not correspond to any of the documented methods. I would suggest changing your code to pass a single config argument. You can move your current callback to the done field of that config object. Something like this:
jsdom.env({
html: body,
scripts: ['http://code.jquery.com/jquery-1.6.min.js'],
done: function (err, window) {
//Use jQuery just as in a regular HTML page
var $ = window.jQuery;
res.send($('title').text());
}
});
