把这个放在模板的末尾:

var scripts =  document.getElementsByTagName('script');
var torefreshs = ['myscript.js', 'myscript2.js'] ; // list of js to be refresh
var key = 1; // change this key every time you want force a refresh
for(var i=0;i<scripts.length;i++){ 
   for(var j=0;j<torefreshs.length;j++){ 
      if(scripts[i].src && (scripts[i].src.indexOf(torefreshs[j]) > -1)){
        new_src = scripts[i].src.replace(torefreshs[j],torefreshs[j] + 'k=' + key );
        scripts[i].src = new_src; // change src in order to refresh js
      } 
   }
}

请不要提供错误的信息。 缓存api是一种不同于http缓存类型的缓存

当服务器发送正确的头文件时，HTTP缓存被触发，你不能用javasvipt访问。

另一方面，缓存api在你想要的时候被触发，它在与service worker一起工作时很有用，所以你可以从这种类型的缓存中交叉请求和回答它 参见:插图1插图2课程

你可以使用这些技巧让你的用户总是有新鲜的内容:

Use location.reload(true) this does not work for me, so I wouldn't recomend it. Use Cache api in order to save into the cache and intersect the request with service worker, be carefull with this one because if the server has sent the cache headers for the files you want to refresh, the browser will answer from the HTTP cache first, and if it does not find it, then it will go to the network, so you could end up with and old file Change the url from you stactics files, my recomendation is you should name it with the change of your files content, I use md5 and then convert it to string and url friendly, and the md5 will change with the content of the file, there you can freely send HTTP cache headers long enough

我建议你看第三部

你不能用javascript清除缓存。 一种常见的方法是将修订号或最近一次更新的时间戳附加到文件中，如下所示:

myscript.123.js

or

myscript.js吗?更新= 1234567890

试试这个

 <script language="JavaScript" src="js/myscript.js"></script>

:

 <script language="JavaScript" src="js/myscript.js?n=1"></script>

如果你使用php可以做:

 <script src="js/myscript.js?rev=<?php echo time();?>"
    type="text/javascript"></script>

我已经通过使用解决了这个问题 ETag

Etag类似于指纹，如果给定URL上的资源发生变化，则必须生成一个新的Etag值。比较它们可以确定资源的两个表示是否相同。
