Firstly the text files are going to have to be publicly accessible. 首先，文本文件必须是可公开访问的。 They cannot exist in a private context on the server, as JavaScript is a client side technology. 它们不能存在于服务器的私有上下文中，因为JavaScript是一种客户端技术。

Once they are public, you can simply do an AJAX request on the file location, and then parse them as required. 它们公开后，您只需在文件位置发出AJAX请求，然后根据需要解析它们。

If having them in a public location is going to be a problem, you will need to have a page that serves them to authenticated accounts only, so only people that are logged in can view them. 如果将它们放在公共场所将是一个问题，则需要有一个仅将它们提供给经过身份验证的帐户的页面，因此只有登录的用户才能查看它们。 This means they will have to be served via a server side script at some point, which the AJAX request can then fetch as required. 这意味着它们将必须在某个时候通过服务器端脚本提供服务，然后可以根据需要获取AJAX请求。

However if you take this approach, you might as well take out the AJAX and just have the server side script do the processing for you and feed out the result. 但是，如果您采用这种方法，则最好删除AJAX，只让服务器端脚本为您进行处理并提供结果。
