Properties

This interface also inherits properties from its parent interface, SVGGeometryElement.

SVGEllipseElement.cx Read only: This property returns a SVGAnimatedLength reflecting the cx attribute of the given <ellipse> element.
SVGEllipseElement.cy Read only: This property returns a SVGAnimatedLength reflecting the cy attribute of the given <ellipse> element.
SVGEllipseElement.rx Read only: This property returns a SVGAnimatedLength reflecting the rx attribute of the given <ellipse> element.
SVGEllipseElement.ry Read only: This property returns a SVGAnimatedLength reflecting the ry attribute of the given <ellipse> element.

Methods

This interface doesn't implement any specific methods, but inherits methods from its parent interface, SVGGeometryElement.

Example

SVG content

<svg width="200" height="200" xmlns="http://www.w3.org/2000/svg">
  <ellipse cx="100" cy="100" rx="100" ry="60" id="ellipse"
      onclick="outputSize();"/>
</svg>

JavaScript content

function outputSize() {
  var ellipse = document.getElementById("ellipse");
  // Outputs "horizontal radius: 100 vertical radius: 60"
  console.log(
    'horizontal radius: ' + ellipse.rx.baseVal.valueAsString,
    'vertical radius: ' + ellipse.ry.baseVal.valueAsString
  )
}
