I need some way of overcoming the incompatibility issues between canvas and IE8.

I'm currently using charts.js to render certain charts onto a canvas, which obviously doesn't display in IE8.

My ideal approach would be to detect compatibility on the client and then fallback to an ajax request for a jpeg version of the canvas (i.e. the chart is rendered on the server) but I can't find a way to do this. I'm currently open to any other feasible suggestions.

NOTE: I have already opted for charts.js, unfortunately switching plugins is not an option at this point.

  • What strange situation is forcing you to support IE8? Also: do you have to support other browsers? If you can adjust IE8 out of your scope/requirements your life will be much better. Having been there and done that (my strange reason was that some parts of the Goverment refused to upgrade/update things, ever.) Supporting IE8 and anything else, Almost involved developing two versions of everything. A version that works for IE8 (but is painfully slow/laggy), and a version for everything else. – Lyndon White Jun 6 '14 at 5:53

You can use HTML5Shiv. It adds (partially) HTML5 support for old browsers. You must include it as the first script in the <head>. You can include it only for legacy IE versions with something like this:

<!--[if IE]><script type="text/javascript" src="js/html5shiv.js"><![endif]-->
