The releasePointerCapture()
method of the Element
interface releases (stops) pointer capture that was previously set for a specific (PointerEvent
) pointer.
See the Element.setPointerCapture()
method for a description of pointer capture and how to set it for a particular element.
releasePointerCapture(pointerId)
This example sets pointer capture on a <div>
when you press down on it. This lets you slide the element horizontally, even when your pointer moves outside of its boundaries.
<div id="slider">SLIDE ME</div>
div {
width: 140px;
height: 50px;
display: flex;
align-items: center;
justify-content: center;
background: #fbe;
}
function beginSliding(e) {
slider.onpointermove = slide;
slider.setPointerCapture(e.pointerId);
}
function stopSliding(e) {
slider.onpointermove = null;
slider.releasePointerCapture(e.pointerId);
}
function slide(e) {
slider.style.transform = `translate(${e.clientX - 70}px)`;
}
const slider = document.getElementById("slider");
slider.onpointerdown = beginSliding;
slider.onpointerup = stopSliding;
