我想加载一个本地 .txt 文件并使用 javascript 中的内容。我的本地文件就像 C:\Users\Who\Desktop\file.txt 谢谢

by default javascript is NOT allowed to access local file system for security reasons. If you want to allow a particular script access to a local file then you have 2 options.
默认情况下，出于安全原因，不允许 javascript 访问本地文件系统。如果要允许特定脚本访问本地文件，则有 2 个选项。
1a. Change your model, put the text file on a server and load from there...
1a. 更改您的模型，将文本文件放在服务器上并从那里加载...
1b. Run a local webserver :-)
1b. 运行本地网络服务器:-)
2 ... this becomes browser dependent,
2 ...这变得依赖于浏览器，
In particular,
特别是，
you can create a signed javascript for Mozilla like browsers, see http://www.mozilla.org/projects/security/components/signed-scripts.htmlfor details
you can create an ActiveX plugin that allows local access for IE types... ;
and for anything else again read up o local access.
您可以为 Mozilla 之类的浏览器创建一个签名的 javascript ，详情请参见http://www.mozilla.org/projects/security/components/signed-scripts.html
您可以创建一个 ActiveX 插件，允许对 IE 类型进行本地访问...；
对于其他任何事情，请再次阅读 o 本地访问。

You can't, place it on a web server (on the same domain you are working on) then perform an AJAX GET.
你不能，把它放在一个网络服务器上（在你工作的同一个域上）然后执行 AJAX GET。
var file = (function func1() {
var result;
$.ajax({
type: "GET",
url: file,
async: false,
success: function(data){
result = data;
}
});
return result;
})();

I'm guessing by your question that maybe you're trying to do some form of JS templating. In which case, you'd probably want to look at something like this: http://github.com/andyet/icanhaz.js
我猜你的问题，也许你正在尝试做某种形式的 JS 模板。在这种情况下，您可能想查看以下内容：http: //github.com/andyet/icanhaz.js
The short of it is, you can store text that you want access to in JS in this way:
简而言之，您可以通过这种方式在 JS 中存储您想要访问的文本：
<script id="my_snippet" type="text/html">
Whatever random text here, format doesn't really matter,
you can use whatever unless you're trying to serve it as xml.
</script>
It's actually valid in HTML 5. Then you can retrieve the contents in JS like so:
它实际上在 HTML 5 中有效。然后您可以像这样在 JS 中检索内容：
$('#my_snippet').html();
$('#my_snippet').html();
ICanHaz.js abstracts this all a bit for you so if you're templating... I'd recommend using that instead.
ICanHaz.js 为你抽象了这一切，所以如果你正在做模板......我建议改用它。

Allowing a website to access c:\path\file.xxx on the client's computer is a major security breach. Javascript will never have this functionality.
允许网站访问客户端计算机上的 c:\path\file.xxx 是一个重大的安全漏洞。Javascript 永远不会有这个功能。

You could instantiate a WebBrowser control, use C# to load the .txt file contents into a div or something and go from there.
您可以实例化 WebBrowser 控件，使用 C# 将 .txt 文件内容加载到 div 或其他内容中，然后从那里开始。
