在客户端加载外部脚本

Question

I'm using this method when file is loaded:

$("<script/>", { "class": "test", "src": 'http://www.externalSite.com/js/xxx.js' }).appendTo("head");

the file is loaded fine and no problem with it.

Im try to make an ajax call in this file to get some data from the server DB, and then simply alert the result.

When Im making the call from the same server it works good, but when Im trying to call this script from an outside server it alerts an empty string

Answer 1

Ajax不能用于从另一台服务器获取数据，这被称为同一原始策略，主机名和端口号必须相同才能发出请求。
