Document: lostpointercapture event - Web APIs 编辑

The lostpointercapture event is fired when a captured pointer is released.

Examples

This example listens for the lostpointercapture event, and captures the pointer for an element on pointerdown. When the user subsequently releases the pointer, the lostpointercapture event will be fired.

const para = document.querySelector('p');

document.addEventListener('lostpointercapture', () => {
  console.log('I\'ve been released!')
});

para.addEventListener('pointerdown', (event) => {
  para.setPointerCapture(event.pointerId);
});

The same example, but using the onlostpointercapture event handler property:

const para = document.querySelector('p');

document.onlostpointercapture = () => {
  console.log('I\'ve been released!')
};

para.addEventListener('pointerdown', (event) => {
  para.setPointerCapture(event.pointerId);
});
