我救了一个页面在硬盘上，然后我打开了它，并想从已保存的HTML文件连接到互联网上的服务器的网站。当试图做使用 XMLHtt prequest 从装载在浏览器中手动将文件中的HTTP请求，它基本上做不到。能否请你告诉我，我应该怎么办？或者，这可能吗？

I saved a page on a hard drive then I opened it and wanted to connect from a saved html file to the server website on the Internet. When trying to do a HTTP request using XMLHttpRequest from a file that were loaded in browser manually, it basically fails to do. could you please tell me what should i do? Or is it possible?

推荐答案

除非是跨域xmlHtt prequest，它会由于同源策略的失败。

Unless it is a cross domain xmlHttpRequest, it will fail due to same-origin policy.
