您无法与本地文件的工作。本地文件系统，沙箱，这样，比如你不能双击一个HTML文档中的电子邮件附件，在浏览器中打开它，有它你的私人文件上传到发件人的服务器。
如果你想在本地测试阿贾克斯，然后通过它安装一个本地网络服务器和测试。
Okay i cannot solve this problem for 2 days straight.. This examlpe here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_xml2 works just fine on the w3schools site. But when i copy and paste the code in notepad++. It doesn't work. I have the XML file downloaded. Than i was reading that AJAX doesn't support work with local files. I don't get this?? I have an assingment for school to work with a local XML file. How can i work with local XML file and AJAX when AJAX doesn't support working with local files. And the only response that i get from the teaching assistant is that i should use firefox... But No.. it doesn't work on : Chrome, Internet Explorer, Mozila, Opera.. basicaly nothing...
I know that something similar has been asked here but i just can't make it work. If anyone got any idea how can i modify this given code to work localy, i would be thankful.. THANKS in advance..

You can't work with local files. The local file system is sandboxed so that, for example, you can't double click an HTML document in an email attachment, open it in your browser and have it upload your private files to the sender's server.
If you want to test Ajax locally, then install a local webserver and test through it.
