Loading the html of a different website

I'm looking to get some data from a Facebook page of a restaurant, but I'm kinda stuck. I want to load some divs from the facebook page of the restaurant, then get the ID's of the divs, since they contain some information i would like to use. Ive tried using the .load function from jQuery, but no luck. Of all the answers I've seen, they all include a url that's something like somefile.html. Is it possible to load the divs ids and some innerHTML from a live page like Facebook? Are they somehow downloading the html to a file then using that? Keep in mind I know nothing about PHP, so any solutions? Thanks!

The right way to do it would be though Facebooks graph API, take a look at this site and see if it offers the information you need https://developers.facebook.com/docs/graph-api/reference/page/

NOTE

As comments have pointed out, "web scraping" is FORBIDDEN on Facebook.com by Facebook policy. http://www.facebook.com/apps/site_scraping_tos_terms.php

Technically, I don't think this is possible with Facebook and just JavaScript.

In general, using just JavaScript, one solution would be to load the (external) site like FaceBook into an Iframe, and then grab all the DIVs and search the DOM that's loaded into the iFrame. However, I believe FaceBook (and other sites) set something called "CORS Request Headers" which prevent the page from loading into an iFrame -- also, as far as I know, this cannot be hacked around except to use another language to pull the HTML as a file (like with PHP).
