Web/API/Element/hasPointerCapture

The hasPointerCapture() method of the Element interface sets whether the element on which it is invoked has pointer capture for the pointer identified by the given pointer ID.

Syntax

targetElement.hasPointerCapture(pointerId);

Parameters

pointerId: The pointerId of a PointerEvent object.

Return value

A Boolean value — true if the element does have pointer capture, false if it doesn't.

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;
    }
  </script>
  <body onload="init();">
    <div id="target">Touch this element with a pointer.</div>
  </body>
</html>
