When someone interacts with a webpage, the browser sends events to the relevant JavaScript code. The pointercancel event happens when the browser cancels an active pointer interaction.
When pointercancel happens
The browser cancels an active pointer interaction.
You can listen for it using addEventListener(). That keeps event handling separate from HTML attributes such as onclick and works well with modern code organization.
A small working example
<div id="demo-target" style="padding: 2rem; border: 1px solid">Use mouse, touch or pen here</div>
<p id="event-status" role="status">Waiting for pointercancel...</p>
<script>
const eventTarget = document.getElementById("demo-target");
const eventStatus = document.getElementById("event-status");
if (eventTarget) {
eventTarget.addEventListener("pointercancel", (eventDetails) => {
eventStatus.textContent = "pointercancel event received";
console.log(eventDetails.type, eventDetails.target);
});
}
</script>
Reading the code
The browser listens for pointercancel on the relevant target. When the event occurs, the callback receives eventDetails, updates the status message and logs the event name and target in Developer Tools.
Start a touch gesture that the browser takes over for panning or zooming.
Pointer events work across several input devices. Touch events are tied to touch-capable platforms; when possible, prefer a pointer-based implementation with accessible keyboard controls.
Try it in your browser
Open the page, show the Console panel, and follow this test: Start a touch gesture that the browser takes over for panning or zooming. Then change one thing in the example and observe whether the event still fires.
Common Beginner Mistakes
- Expecting
pointercancelto fire without its required user action or browser condition. - Start a touch gesture that the browser takes over for panning or zooming.
- Adding repeated event listeners without considering cleanup or unwanted side effects.
Key Takeaways
