由于 document.domain 以避免被Same Origin策略拒绝访问.
Making a call to a sub domain is seen as a different domain because of the Same Origin policy. Make sure that you are setting document.domain to avoid access denied with the Same Origin policy.
要同步document.domain，您需要在两个位置进行设置.添加一个用于设置域的脚本标签，然后您需要在页面上具有一个iframe，以便在另一个域上设置相同的内容.
To get the document.domain in sync you need to set it in two places. Add a script tag that set the domain, and you need to have an iframe on the page that sets the same thing on the other domain.
通过"www.example.com"进行Ajax调用并正在调用"ajax.example.com"的页面:
The page that the Ajax call is made from "www.example.com" and is calling "ajax.example.com":
<script type="text/javascript">
document.domain = "example.com";
</script>
<iframe src="http://ajax.example.com/domainCode.html"></iframe>
"domainCode.html"将仅包含脚本标记
The "domainCode.html" would just contain the script tag
<html>
<head>
<script type="text/javascript">
document.domain = "example.com";
</script>
</head>
<body>
</body>
</html>
有了这个，您应该能够在子域之间进行通话.
With that in place you should be able to talk between your sub domains.
