access other site using javascript/html5

Question

Just wonder is there a way for visitor

when he visits 'a.com' and communicates with the site using XMLHttpRequest, there are some javascript/html5 code hosted on a.com make the visitor can access the content of another site b.com

I memorise that for the security reason this is forbid.

Just make sure if it is possible or not

do you mean static html is ok, and url likes http://www.b.com?ref1=abc is ok also, but post to site b.com is forbid? — arachide, Oct 19 '13 at 15:29
your question is too broad for this forum, you need to be more specific http://stackoverflow.com/help/dont-ask — Christophe, Oct 19 '13 at 15:37

It is possible using JSONP or CORS.

You can read a comparison of the two here.
