SVGAnimatedNumberList: baseVal property

The baseVal read-only property of the SVGAnimatedNumberList interface represents the base (non-animated) value of an animatable attribute that accepts a list of <number> values.

This property reflects the viewBox attribute of the <svg> element, the values attribute of the feColorMatrix element and the points attribute of the <rect>, <polygon>, or <polyline> element as a readonly SVGNumberList, providing access to a static list of points defined by the points attribute.

Value

An SVGNumberList object representing the base value of the attribute. The list contains one or more numbers corresponding to the individual number values specified in the attribute.

Examples

const rect = document.querySelector("rect");

// Set the animatable 'points' attribute with number values
rect.setAttribute("points", "10,10 20,10 20,20 10,20");

// Access the SVGAnimatedNumberList object
const points = rect.points;

// Modify the base value
points.baseVal = [10, 15, 25, 30];

// Verify the reflected attribute value
console.log(rect.getAttribute("points")); // Output: "10,15 25,30"
