Question

Node.js noob. I am using node.io to scrape websites but I would love to use jquery within node.io. The $ object provided by node.io doesn’t provide much flexibility.

var nodeio = require('node.io'), options = {timeout: 10},
    jQuery = require('jquery');

exports.job = new nodeio.Job(options, {
    input: ['hello', 'foobar', 'weather'],
    run: function (keyword) {
        this.getHtml('http://www.google.com/search?q=' + encodeURIComponent(keyword), function (err, $) {

            // SOMEHOW CREATE THE JQUERY OBJECT USING $

            var results = $('#resultStats').text.toLowerCase();
            this.emit(keyword + ' has ' + results);
        });
    }
});

Can anyone help?

UPDATE

I din’t notice that node.io had an option to use jquery with the jsdom:true option. It doesn’t work even when I use this option, I always get a timeout error OR $ is undefined error.

Ok, figured out the problem.

node.io has an option to use jquery, you need to pass this option jsdom:true. The version of node.io (0.3.0) I was using had a bug in it which always returned a timeout.

  // lib/node.io/dom.js
  window.onload = function() {
    callback.apply(self, [null, $, data, headers, response]);
  }

Now this is fixed in node.io version 0.3.1

Thank you all for your response!
