The SVGRectElement interface provides access to the properties of <rect> elements, as well as methods to manipulate them.

This interface also inherits properties from its parent, SVGGeometryElement.

SVGRectElement.x Read only

Returns an SVGAnimatedLength corresponding to the x attribute of the given <rect> element.

SVGRectElement.y Read only

Returns an SVGAnimatedLength corresponding to the y attribute of the given <rect> element.

SVGRectElement.width Read only

Returns an SVGAnimatedLength corresponding to the width attribute of the given <rect> element.

SVGRectElement.height Read only

Returns an SVGAnimatedLength corresponding to the height attribute of the given <rect> element.

SVGRectElement.rx Read only

Returns an SVGAnimatedLength corresponding to the rx attribute of the given <rect> element.

SVGRectElement.ry Read only

Returns an SVGAnimatedLength corresponding to the ry attribute of the given <rect> element.

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

This example sets the fill color of an SVGRectElement to a random value whenever the user clicks it.

HTML

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <rect
    width="300"
    height="100"
    id="myrect"
    style="fill:rgb(0,0,255);stroke-width:1;stroke:rgb(0,0,0)" />
  <text x="60" y="40" fill="white" font-size="40">Click Me</text>
</svg>

JavaScript

const myRect = document.querySelector("#myrect");

myRect.addEventListener("click", () => {
  const r = Math.floor(Math.random() * 255);
  const g = Math.floor(Math.random() * 255);
  const b = Math.floor(Math.random() * 255);
  myRect.style.fill = `rgb(${r}, ${g}, ${b})`;
});

Result

• <rect>
