通过域之间的JavaScript进行通信 [英] Communicating via javascript across domains
问题描述
嘿所有，
这就是情况：
- 两个网站，一个在domain1上，另一个在domain2上br />
- domain1打开一个新窗口，这是一个来自domain2的javascript应用程序
- domain1需要与domain2上的javascript应用程序进行通信
问题出现在最后一步。出于安全原因，浏览器不允许跨域访问
，这是正确的。尽管如此，我仍然需要与应用程序进行通信。我可以重新加载窗口
通过网址传递必要的命令，但这很慢，因为
整个javascript应用程序必须重新加载。
任何人都有任何想法绕过这个限制，这将是半效率，至少比重新加载应用程序更有效吗？签署
由于成本原因，脚本不是一个选项。我可以控制两个
的网站，所以我可以做任何需要做的事情。
问候，
克雷格< br>
Hey all,
Here''s the situation:
- two websites, one on domain1 and the other on domain2
- domain1 opens a new window which is a javascript app from domain2
- domain1 needs to communicate with the javascript app on domain2
The problem occurs in that last step. Browsers don''t allow script access
across domains for security reasons, rightly so. Nonetheless, I still
need to communicate with the application. I can reload the window
passing the necessary commands through the url, but this is slow because
the whole javascript app must reload.
Anyone have any ideas about a way around this limitation that would be
semi-efficient, at least more efficient than reloading the app? Signing
the script isn''t an option for cost reasons. I have control over both
sites, so I can do anything that needs to be done.
Regards,
Craig

嗯，它不是一个跨浏览器的解决方案，但如果你使用超文本
应用程序（HTA），你可以绕过一些安全性。当我想要IE的DOM检查器时，我做了类似
的事情。不幸的是，HTA在IE中只能运行
。我认为其他
系统有类似的浏览器特定解决方案，但我不知道。您可以在以下网址阅读有关HTA的更多信息：

Well, it is not a cross-browser solution, but if you use HyperText
Applications (HTA), you can bypass some security. I did something like
that when I wanted a DOM inspector for IE. Unfortunately HTA only works
in IE. I think there are similar browser-specific solutions for other
systems, but I dont know offhand. You can read more about HTA at:

如果这些网站共享一个公共域，然后您可以使其工作。对于
示例，如果您有''domain1.commom.com''和''domain2.common.com''，那么你可以将
放入< / b ; head> s：
document.domain =''common.com'';
这将绕过相同的网站规则。

If the sites share a common domain, then you can make it work. For
example, if you have ''domain1.commom.com'' and ''domain2.common.com'', you
can put the following in the <head>s:
document.domain = ''common.com'';
This will get around the same site rule.
