I am playing around with CSS
-animated SVG
elements and came across the problem that even though all technologies, which are used, are supported by some browsers the combination is not, i.e. CSS
-animated DIV
s work but SVG
elements don't. I am wondering if there is a way to detect if a browser is capable of animating SVG
elements using CSS
.
Here is a jsFiddle with an example. It works in the latest versions of Chrome, Firefox and Safari. But when opening it with e.g. Firefox 5 only the div
rotates while the rect
doesn't.
You can add an event listener to check for the completion of an animation iteration, and within the corresponding event handler set a flag like supportsSVGKeyFramedAnimatedProps = true
(if the iteration never completes then it is not animating).
elem.addEventListener('animationiteration', eventHandler, false)
This would allow you to 'fall forward' to your SVG animation, instead of providing a fallback.
