我有一些问题与yboussard建议的代码。内j循环不起作用。下面是我成功使用的修改后的代码。

function reloadScripts(toRefreshList/* list of js to be refresh */, key /* change this key every time you want force a refresh */) {
    var scripts = document.getElementsByTagName('script');
    for(var i = 0; i < scripts.length; i++) {
        var aScript = scripts[i];
        for(var j = 0; j < toRefreshList.length; j++) {
            var toRefresh = toRefreshList[j];
            if(aScript.src && (aScript.src.indexOf(toRefresh) > -1)) {
                new_src = aScript.src.replace(toRefresh, toRefresh + '?k=' + key);
                // console.log('Force refresh on cached script files. From: ' + aScript.src + ' to ' + new_src)
                aScript.src = new_src;
            }
        }
    }
}

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
      } 
   }
}

或者你可以通过服务器用file_get_contts读取js文件，然后在js内容的头中放入echo

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。

Maybe "clearing cache" is not as easy as it should be. Instead of clearing cache on my browsers, I realized that "touching" the file will actually change the date of the source file cached on the server (Tested on Edge, Chrome and Firefox) and most browsers will automatically download the most current fresh copy of whats on your server (code, graphics any multimedia too). I suggest you just copy the most current scripts on the server and "do the touch thing" solution before your program runs, so it will change the date of all your problem files to a most current date and time, then it downloads a fresh copy to your browser:

<?php
    touch('/www/control/file1.js');
    touch('/www/control/file2.js');
    touch('/www/control/file2.js');
?>

.．.剩下的程序…

我花了一些时间来解决这个问题(因为许多浏览器对不同的命令有不同的行为，但它们都检查文件的时间，并将其与浏览器中下载的副本进行比较，如果日期和时间不同，将进行刷新)，如果你不能按照假设的正确方式进行，总有另一种可用的更好的解决方案。祝你露营愉快。

如果你使用php可以做:

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