The ariaValueMin property of the Element interface reflects the value of the aria-valuemin attribute, which defines the minimum allowed value for a range widget.
A string which contains a number.
In this example the aria-valuemin attribute on the element with an ID of slider is set to "1". Using ariaValueMin we update the value to "2".
<div
role="slider"
aria-valuenow="1"
aria-valuemin="1"
aria-valuemax="7"
aria-valuetext="Sunday"></div>let el = document.getElementById("slider");
console.log(el.ariaValueMin); // 1
el.ariaValueMin = "2";
console.log(el.ariaValueMin); // 2
