推荐答案
您请求的页面位于其他域中，因此跨域策略适用.您只能在远程服务器允许的情况下跨域访问数据(我相信，只能使用JSONP，如果我对此有误，请纠正我).如果您想获取Google页面的源代码，则需要使用服务器端脚本作为jQuery的代理:
You are requesting a page that is on a different domain so Cross-Domain-Policies apply. You can only access data cross-domain if the remote-server allows it (and only using JSONP I believe, anyone please correct me if I'm wrong on this). If you want to grab the source of a Google page, you will need to do it with a server-side script as a proxy for your jQuery:
$(function() {
//notice the client-side code (JS) is requesting a page on the save domain
$("#dialog").load('my-script.php #maia-main');
});
在my-script.php中，您将获取所需的远程页面:
And in my-script.php you would grab the remote page you want:
<?php
//PHP, like all server-side languages has no cross-domain-policy
echo file_get_contents('http://www.google.com/intl/en/about/index.html');
?>
file_get_contents()的文档: http://www.php.net/file_get_contents
