A simple, beautiful, unobtrusive JavaScript include which prompts old IE users to install Chrome.
Script is not downloaded for other browsers, so performance is not impacted.
(Coming soon.)
-
Include jQuery in your
<head> -
Put this snippet immediately after your
<body>tag:<!-- Display a notice to IE 8 and below, recommending they install Chrome --> <!--[if lte IE 8]> <script src="//cdn.jsdelivr.net/cookies.js/0.4.0/cookies.min.js"></script> <script src="//yumpdigital.github.io/Upgrade-IE-Already/ie-upgrade-prompt.js"></script> <![endif]--> -
You can configure the "IE 8" conditional comment to refer to any other version of IE that you prefer.
The JS code is in the gh-pages branch of this repository.

- Removing requirement for jQuery
- Making cookie library optional
- Asynchronous (non-blocking) loading - although I'm not particularly concerned with optimizing performance for old browsers, argh.
