jquery ajax readystate 0 responsetext status 0 stext错误

I am getting the following error: jquery ajax readystate 0 responsetext status 0 statustext error when giving it: url(http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm), however it's working fine when I give it url(localhost:""/embparse_page) on my localhost.

我得到了以下错误:jquery ajax readystate 0 responsetext status 0在给出url时出现了:url(http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm)，但是当我在本地主机上给它url(localhost:""/embparse_page)时，它工作得很好。

I have tried using the headers which I found on a Google search, and I have used beforeSend:"" too, but it's still not working.

我尝试过使用在谷歌搜索中找到的标题，我也使用了前面的“”，但是它仍然不能工作。

I think the main problem is: XMLHttpRequest cannot load http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm. Origin "local server" is not allowed by Access-Control-Allow-Origin. but I don't understand it.

我认为主要的问题是:XMLHttpRequest不能加载http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm。访问控制允许的源不允许“本地服务器”。但我不明白。

Can anyone please explain the problem to me, as I'm quite new to this.

谁能给我解释一下这个问题，因为我对这个问题很陌生。
