问题描述
我正在为一个网站使用JavaScript，使用Firefox进行开发，当我刷新页面时，我没有看到我的更改。 JavaScript文件位于外部文件中。我重新加载并刷新了多次页面，但旧的JavaScript文件仍然被缓存。最后，我直接在浏览器中加载JavaScript页面，看到旧脚本，点击重新加载，看到我的更改。
如何清除缓存的外部JavaScript文件？当我告诉客户端所做的更改时，我也需要知道这一点，以便他们没有看到旧的缓存功能。在Firefox中，您可以安装名为 Web Developer Toolbar 的插件，该插件有一个<$ c $ c> appcache clear command
我认为没有办法通过编程来实现，但是您可以使用类似于
< script type =text / javascriptsrc ='js / my.js？x =<？php echo rand （0,100）？>'>< / script>
I'm working on JavaScript for a site, developing with Firefox, and when I refresh the page, I don't see my changes. The JavaScript file is in an external file. I reloaded and refreshed the page several times, but the old JavaScript file was still cached. Finally, I loaded the JavaScript page in the browser directly, saw the old script, hit 'reload', and saw my changes.
How can I clear cached external JavaScript files? I'll need to know this also when I tell the client that the changes are made, so that they aren't seeing the old cached functionality.
In Firefox you can install a plugin called Web Developer Toolbar which has a appcache clear command
I think there is no way to do it programmatically but you could give a hint to the browser using something like
<script type="text/javascript" src='js/my.js?x=<?php echo rand(0,100) ?>'></script>
