SVGAnimationElement: getSimpleDuration() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The SVGAnimationElement method getSimpleDuration() returns a float representing the number of seconds for the simple duration for this animation.

Simple duration refers to the length of time an animation is supposed to run for a single iteration, without considering repeats, restarts, or extensions.

This property reflects the dur attribute of the <animate>, <animateMotion> or <animateTransform> element.

Syntax

js
getSimpleDuration()

Parameters

None (undefined).

Return value

A float.

Exceptions

NotSupportedError DOMException

Thrown if the SVGAnimationElement's simple duration is undefined (e.g., the end time is indefinite). This happens when the dur attribute is set to indefinite or is undefined, as then the simple duration is considered undefined.

Examples

This example demonstrates how the dur="3s" attribute defines a simple duration of 3 seconds.

html
<svg width="200" height="200" viewBox="0 0 200 200">
  <circle cx="50" cy="50" r="20" fill="rebeccapurple">
    <animate
      attributeName="cx"
      from="50"
      to="150"
      dur="3s"
      repeatCount="indefinite" />
  </circle>
</svg>
js
const animationElement = document.querySelector("animate");

const simpleDuration = animationElement.getSimpleDuration();
console.log(`The simple duration is: ${simpleDuration} seconds`); // Output: 3

Since repeatCount="indefinite" specifies continuous looping, the effective duration is infinite, but the simple duration remains 3 seconds per iteration.
