在服务器上修改时，JavaScript文件不会在浏览器中重新加载 [英] JavaScript file not reloading in browser when modified on server

问题描述

所以我有这个ASP.Net 2.0网站，它使用JS文件中包含的功能。当一个网页加载js文件加载正常。但是当我在服务器上更改该文件中的某些内容时，更改不会传播到用户的浏览器。它根据过时的文件继续工作。如何强制浏览器从服务器重新加载修改后的文件？

So I have this ASP.Net 2.0 website that uses functions contained within a JS file. When a webpage loads the js file loads fine. But when I change something in that file on the server the changes are not propagated to user's browser. It keeps working according to the out dated file. How can I force the browser to reload the modified file from the server?

推荐答案

一种相当常见的解决方案（也在这里使用）在SO我想）是在javascript文件的url中添加一个查询字符串，其中包含一个版本号。当您更改查询字符串时，浏览器会将其视为新文件并下载而不是从缓存中选择。

One rather common solution (that is also used here at SO I think) is to add a query string to the url of the javascript file, containing a version number. When you change the query string, the browser will treat it as a new file and download it rather than picking it from the cache.

<script type="text/javascript" src="http://example.com/file.js?v=2"></script> 

在上面的例子中，更改 file.js？v = 2 到 file.js？v = 3 会强制浏览器下载文件，而不是加载缓存的 file.js？ v = 2 。

In the above example, changing file.js?v=2 to file.js?v=3 would force the browser to download the file, instead of loading the cached file.js?v=2.
