SVGAnimatedRect: baseVal property

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 baseVal read-only property of the SVGAnimatedRect interface represents the current non-animated value of the viewBox attribute of an SVG element.

This property reflects the SVG element's viewBox attribute value as a read-only DOMRect object. It provides access to the static rectangle defined by the viewBox attribute, including the x, y, width, and height values.

Value

A DOMRect object representing the current non-animated value of the viewBox attribute.

Examples

html
<svg viewBox="0 0 200 100" id="mySvg">
  <rect width="100" height="100" fill="blue" />
</svg>
js
const svgElement = document.getElementById("mySvg");
const animatedRect = svgElement.viewBox.baseVal;

// Access the non-animated base value
console.log(animatedRect.x); // 0
console.log(animatedRect.y); // 0
console.log(animatedRect.width); // 200
console.log(animatedRect.height); // 100
