It doesn’t work – “unsupported removeEventListener”.
I guess it is only a polyfill for addEventListener, not for removeEventListener ;
But you should be able to add this feature in this example pretty easily I guess !
I thought I would give my to pennies, for those looking for a polyfill for both add and remove EventListener, try the MDN website:
https://developer.mozilla.org/en-US/docs/Web/API/EventTarget.addEventListener$revision/650019#Compatibility
what about this?
is more simple but i think it will work on ie8+
