Syntax

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.

<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>

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.
