如何在JavaScript中加载HTML页面

Question

I am trying to load a website into JavaScript so I can scrape it. My question is how would i load the website into client side JavaScript? I have tried loading it into a iframe and a JavaScript object element.

You'd use AJAX. In most cases, though, the same-origin policy will trip you up - JavaScript on example.com can't access the source code of example.net because they're different domains.

If both sites are under your control, CORS can fix this . If you're trying to scrape something like Facebook, you'd have to proxy the requests with some sort of server-side language like PHP.
