iframe被拒绝

I was recently rolling my own AJAX upload script, posting a form to a hidden IFRAME and using the load event to know when the upload was complete.  When the upload completed, I wanted to access the IFRAME content so I could verify that the upload completed successfully.  Surprisingly I ran into the following JavaScript error:

最近，我正在滚动自己的AJAX上传脚本，将表单发布到隐藏的IFRAME中，并使用load事件知道何时完成上传。 上传完成后，我想访问IFRAME内容，以便可以验证上传成功完成。 令人惊讶的是，我遇到了以下JavaScript错误：

Error: Permission denied to access property 'document'

If you were using jQuery, you may see this error instead:

如果您使用的是jQuery，则可能会看到此错误：

Error: Permission denied to access property 'nodeType'

This confused me because I knew that my IFRAME was accessing an address on the same host, including protocol. After pulling my hair out and sending a plea for ideas on Twitter, Daniel Buchner mentioned a server-side header that I needed to adjust to allow for accessing that frame's nodes: `x-frame-options`. The header can have values of `NONE` or `SAMEORIGIN`, and setting the `x-frame-options` to `SAMEORIGIN` fixed my issue!

这让我感到困惑，因为我知道我的IFRAME正在访问同一主机上的地址，包括协议。 在拔出头发并在Twitter上发表想法请求后，Daniel Buchner提到了服务器端标头，我需要对其进行调整以允许访问该框架的节点： `x-frame-options` 。 标头可以具有`NONE`或`SAMEORIGIN`值，并且将`x-frame-options`为`SAMEORIGIN`解决我的问题！

If you continue seeing a "Permission Denied" error, it's very possible you're trying to do a cross-origin request, and that simply wont allow you access to the IFRAME content, unless a CORS configuration has been added.

如果您继续看到“权限被拒绝”错误，则很可能是您尝试进行跨域请求，并且除非您添加了CORS配置，否则根本就不允许您访问IFRAME内容。
