重新执行JavaScript文件 [英] Re-executing JavaScript files

问题描述

之前我问过这类问题（应用程序无法动态_re_load JavaScript文件）但我无法解决问题（如果它有任何解决方案），所以我将以另一种方式，更简单的方式：

I asked this sort of question before ( Application fails to dynamically _re_load JavaScript files ) but I couldn't quite resolve the problem (if it has any solution), so I will put this in another fashion, a simpler one:

可以从浏览器的内存中卸载文件以便后重新加载吗？

（显然删除标签是不够的。）

Can one unload a file from the browser's memory for posterior reloading?
(Removing the tag is not enough apparently.)

或更相关，如果在删除标签后重新插入标签，该代码是否重新运行（显然不是）？

Or more relevant, if a reinsert the tag after removing it, is that code rerun (apparently not)?

如何完成后者？

提前致谢。

推荐答案

您可以生成一个随机数，然后将其附加到文件名末尾这个： ... / script.js？r = 0.25300762383267283 。然后浏览器会认为它是一个新文件，而不是从缓存中引用它。

You could generate a random number and then attach it to the end of the filename like this: .../script.js?r=0.25300762383267283. Then the browser would think it's a new file and not reference it from the cache.
