Current behavior
Errors are thrown during collection of animation styles (in older browsers).
The problem is on this line:
|
return element.style[ANIMATION_PROP + name]; |
Most of browsers will return empty string if the style property is not set. But some browsers (like Chrome on Android 4.4) returns null instead of empty string.
Several string functions are applied on the output of the method "getAnimationStyle" - like trim, split, indexOf, etc... But if the output of the"getAnimationStyle" is null, exception is thrown.
Simple fix of this bug:
return element.style[ANIMATION_PROP + name] || '';
Expected behavior
Animation should work without errors.
Minimal reproduction of the problem with instructions
What is the motivation / use case for changing the behavior?
