How to dynamically loop through webpages using nightmareJS and cheerio?

Question

var scrape = new Nightmare({
        show: false
    })
    .goto(urlOb.url)
    .wait(1000)
    .evaluate(function() {
        return document.body.innerHTML;
    }).end().then(function(html) {
      if (html == undefined) {
        console.log('========================');
        console.log('html not there!');
        console.log(arg);
        console.log('========================');
        return;
      }

  var $ = cheerio.load(html);

I need for this scrape to jump to the next page once it's done scraping the first page. I've been working with the .click(), .visible() function in addition to other nightmareJS native functions, but I keep coming up short. Any thoughts on this?
