SVGEllipseElement: cy 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.
Thecy read-only property of theSVGEllipseElement interface describes the y-axis coordinate of the center of the ellipse as anSVGAnimatedLength. It reflects the computed value of thecy attribute on the<ellipse> element.
The attribute value is a<length>,<percentage>, or<number>. The numeric value of theSVGAnimatedLength.baseVal is the y-coordinate of the ellipse's center in the user coordinate system.
Value
Example
Given the following SVG:
html
<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg"> <ellipse cx="50" cy="75" rx="30" ry="20" fill="blue" /> <ellipse cx="25%" cy="50%" rx="10%" ry="5%" fill="red" /></svg>We can access the computed values of thecy attributes:
js
const ellipses = document.querySelectorAll("ellipse");const cyPos0 = ellipses[0].cy;const cyPos1 = ellipses[1].cy;console.dir(cyPos0.baseVal.value); // output: 75console.dir(cyPos1.baseVal.value); // output: 100 (50% of the viewBox height, 200)Specifications
