Answer 1

You cannot do a xhr (ajax) request to another domain. Browsers implement a same domain policy. Your three choices are to use a jsonp call, use a server side proxy your side to make the request or use an iFrame to make the request.

Answer 2

You are attempting "cross-site scripting", that is you are accessing a different site than the one that served up the javascript in the first place. This is usually forbidden by the browser for (good) security reasons.

If your server can see the other site then you can create a proxy service. In doing so you are taking some responsibility for the content so served.
