推荐答案
否，您不能物理删除缓存的文件。相反，您可以动态生成到文件的链接，例如
No you cannot physically delete cached file. Instead you can generate link to the file dynamically, for example
<script type="text/javascript">
document.write('<img id="without-cache" src="image.jpg?v=' + new Date().getTime() + '" />');
</script>
并最终使用不同的？v = 当您要重新加载而不从缓存中加载它时。
and eventually change the source with different ?v= when you want to reload it without loading it from cache.
$("#without-cache").attr("src", "image.jpg?v=" + new Date().getTime());
