Ajax请求子域

Question

Is there a way to get ajax requests from http://foobar.com to snatch data from pages such as http://sub1.foobar.com/choco.php ?

It seems subdomain requests are still not allowed via javascript

Answer 1

If the data is not sensitive, you may use JSONP (JSON with Padding) as an alternative.

Answer 2

JSONP（如Andrew 所述 ）或代理脚本 。

Answer 3

您可以将Access-Control-Allow-Origin标头用于现代浏览器，并将请求包装在本地域中以用于古董浏览器。
