Another possible cause of this is when you are working with a .html file directly on the file system. For example, if you're accessing it using this url in your browser: C:/Users/Someguy/Desktop/MyProject/index.html
另一个可能的原因是当您直接在文件系统上使用 .html 文件时。例如，如果您在浏览器中使用此 url 访问它：C:/Users/Someguy/Desktop/MyProject/index.html
If that then has to make an ajax request, the ajax request will fail because ajax requests to the filesystem are restricted. To fix this, setup a webserver that points localhost to C:/Users/Someguy/Desktop/MyProjectand access it from http://localhost/index.html
如果然后必须发出 ajax 请求，则 ajax 请求将失败，因为对文件系统的 ajax 请求受到限制。要解决此问题，请设置一个指向 localhostC:/Users/Someguy/Desktop/MyProject并从中访问它的网络服务器http://localhost/index.html

Sounds like you are breaking the same origin policy.
听起来您违反了同源政策。
Sub domains, different ports, different protocols are considered different domains.
子域、不同的端口、不同的协议被认为是不同的域。

Try adding Access-Control-Allow-Origin:*header to the server side script that feeds you the XML. If you don't do it in PHP (where you can use header()) and try to read a raw XML file, you probably have to set the header in a .htaccess file by adding Header set Access-Control-Allow-Origin "*". In addition you might need to add Access-Control-Allow-Headers:*.
尝试向Access-Control-Allow-Origin:*向您提供 XML 的服务器端脚本添加标头。如果您不在 PHP（可以使用header()）中执行此操作并尝试读取原始 XML 文件，则您可能必须通过在 .htaccess 文件中添加 .htaccess 文件来设置标头Header set Access-Control-Allow-Origin "*"。此外，您可能需要添加Access-Control-Allow-Headers:*.
Also I'd recommend to replace the * in production mode to disallow everybody from reading your data and instead add your own url there.
此外，我建议在生产模式中替换 * 以禁止所有人读取您的数据，而是在那里添加您自己的 url。

Without code impossible to say, but you could be running foul of the cross-site ajax limitation: you cannot make ajax requests to other domains.
没有代码是不可能的，但是您可能会违反跨站点 ajax 限制：您不能向其他域发出 ajax 请求。
