我需要这样做，以便用户不必执行 [Ctrl+F5] 或手动清除缓存，并且最新版本的 javascript 文件已加载到浏览器中。
The main aim is to load the latest javascript files every time the user visits the website. My application in ASP.NET MVC based and javascript files are included in .csHtml file.

There are other ways to prevent a JavaScript file (or other files) from being cached.
还有其他方法可以防止 JavaScript 文件（或其他文件）被缓存。
Simply append some dummy parameters to the end of the url. For example -
只需将一些虚拟参数附加到 url 的末尾。例如 -
http://www.yourCoolSite.com/resources/js/main.js?r=SOME_RANDOM_VALUE
You would optimally do this on the server side. In PHP, this would look something like this -
您最好在服务器端执行此操作。在 PHP 中，这看起来像这样 -
echo "http://www.yourCoolSite.com/resources/js/main.js?r=".time();
Using the time()function, we append the current epoch timestamp to the URL and therefore guarantee* that the file will appear different to the browser each time.
使用该time()函数，我们将当前纪元时间戳附加到 URL 中，从而保证*该文件每次在浏览器中显示的内容都不同。
