我收到以下错误:jquery ajax readystate 0 responsetext status 0 statustext error给它时: url(http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm)但是当我url(localhost:""/embparse_page)在我的localhost上给它时,它工作正常.
我曾尝试使用我在Google搜索中找到的标题,我也使用beforeSend:""了它,但它仍然无效.
我认为主要问题是:XMLHttpRequest cannot load http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm. Origin "local server" is not allowed by Access-Control-Allow-Origin.但我不明白.
任何人都可以向我解释这个问题,因为我对此很陌生.
