SVGRadialGradientElement: r 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 r read-only property of the SVGRadialGradientElement interface describes the radius of the radial gradient as an SVGAnimatedLength. It reflects the computed value of the r attribute on the <radialGradient> element.
The attribute value is a <length>, <percentage>, or <number>. The numeric value of the SVGAnimatedLength.baseVal is the radius of the radial gradient in the user coordinate system.
Value
Example
Given the following SVG:
html
<svg viewBox="0 0 200 200" xmlns="https://www.w3.org/2000/svg">
<defs>
<radialGradient id="gradient1" cx="50" cy="75" fx="30" fy="60" r="30">
<stop offset="0%" stop-color="blue" />
<stop offset="100%" stop-color="white" />
</radialGradient>
<radialGradient id="gradient2" cx="25%" cy="50%" fx="10%" fy="40%" r="10%">
<stop offset="0%" stop-color="red" />
<stop offset="100%" stop-color="yellow" />
</radialGradient>
</defs>
<rect x="0" y="0" width="200" height="100" fill="url(#gradient1)" />
<rect x="0" y="100" width="200" height="100" fill="url(#gradient2)" />
</svg>
We can access the computed values of the r attributes:
js
const radialGradients = document.querySelectorAll("radialGradient");
const rGradient1 = radialGradients[0].r;
const rGradient2 = radialGradients[1].r;
console.dir(rGradient1.baseVal.value); // output: 30
console.dir(rGradient2.baseVal.value); // output: 20 (10% of 200)
