The animVal read-only property of the SVGAnimatedRect interface represents the current animated value of the viewBox attribute of an SVG element as a read-only DOMRectReadOnly object. It provides access to the rectangle's dynamic state, including the x, y, width, and height values during the animation.
If no animation is applied, the animVal property reflects the SVG element's viewBox attribute value and will be identical to SVGAnimatedRect.baseVal.
A DOMRectReadOnly object representing the animated value of the viewBox attribute.
<svg viewBox="0 0 200 100" id="mySvg">
<rect width="100" height="100" fill="blue" />
</svg>const svgElement = document.getElementById("mySvg");
const animatedRect = svgElement.viewBox.animVal;
// Log the animated value (assuming an animation is applied)
console.log(animatedRect.x);
console.log(animatedRect.y);
console.log(animatedRect.width);
console.log(animatedRect.height);
