JavaScript - 缓存书签，但始终加载最新版本

Question

I'm working on a JavaScript bookmarklet that lets users send a link to a website. Is it possible to cache the bookmarklet but also reload it if a new version is available? (Maybe with htaccess?)

Edit: This is my bookmarklet:

javascript:javascript:(function(){new_script=document.createElement('SCRIPT');new_script.src='https://www.example.com/folder/bookmarklet.js?v=1';document.getElementsByTagName('head')[0].appendChild(new_script);new_script.type='text/javascript';})();

Answer 1

The nature of bookmarklets is that "cache" is irrelevant to them: The exist entirely within the browser's bookmark storage, there is no server call (unless you write one as part of the bookmarklet code).

You could have your bookmarklet load and check a version string from your website using ajax or JSONP.
