I want to use the results to add a hyperlink to an HTML page, but I don't know how to access the results/ return them outside of the callback. I've seen other posts but they all use other libraries and usually

There is a global variable on a page that contains an object that I'd like to set up a scraper for. What's the best way to do this with Node / Express / potentially Cheerio? I understand Cheerio's benefit in traversing a DOM, but I know the name of the global variable I want to scrape and just need to extract its information on a set schedule charly rl Cheerio is just a dom parser, so you wont have acces to any javascriot or any javascript generated content. What you need is something like PhantomJS that simulates a browser. Have a look at this Stackoverflow answer 来源： https://stackoverflow
