A neat trick I sometimes use to "scrape" data from sites that use jquery ajax to load data is to plug in a middleware in jquery xhr:

      $.ajaxSetup({
        dataFilter: function (data, type) {
          if (this.url === 'some url that you want to watch!') {
            // Do anything with the data here
            awesomeMethod(this.data)
          }
          return data
        }
      })

I remember last using it with an infinite-scroll page with a periodic callback that scrolled the page down every 2 seconds, and the `awesomeMethod` just initiated the download. Pasted it all in dev-tools console, and the cheap "scraper" was ready!
