SVGAnimatedLengthList

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

The SVGAnimatedLengthList interface is used for attributes of type SVGLengthList which can be animated.

Instance properties

SVGAnimatedLengthList.baseVal Read only: An SVGLengthList that represents the base value of the given attribute before applying any animations.
SVGAnimatedLengthList.animVal Read only: A read only SVGLengthList that represents the current animated value of the given attribute. If the given attribute is not currently being animated, then the SVGLengthList will have the same contents as baseVal. The object referenced by animVal will always be distinct from the one referenced by baseVal, even when the attribute is not animated.

The SVGAnimatedLengthList interface does not provide any specific methods.
