Examples

<html>
  <script>
    function downHandler(ev) {
      const el = document.getElementById("target");
      // Element 'target' will receive/capture further events
      el.setPointerCapture(ev.pointerId);

      /* ... */

      // Check whether element still has pointer capture
      let pointerCap = el.hasPointerCapture(ev.pointerId);
      if(pointerCap) {
        // We've still got pointer capture
      } else {
        // oops, we've lost pointer capture!
      }
    }

    function init() {
      const el = document.getElementById("target");
      el.onpointerdown = downHandler;
