{{APIRef("SVG")}}
The {{domxref("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 {{SVGAttr("dur")}} attribute of the {{SVGElement("animate")}}, {{SVGElement("animateMotion")}} or {{SVGElement("animateTransform")}} element.
getSimpleDuration()
None ({{jsxref('undefined')}}).
A float.
NotSupportedError {{domxref("DOMException")}}
SVGAnimationElement's simple duration is undefined (e.g., the end time is indefinite). This happens when the {{SVGAttr("dur")}} attribute is set to indefinite or is undefined, as then the simple duration is considered undefined.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.
