The cancelable event property in HTML checks whether an event is a cancelable event or not. The values include TRUE if it is a cancelable event, else FALSE is returned.

event.cancelable
Let us now see an example to implement the cancelable event property −

<!DOCTYPE html>
<html>

<h2>Checking cancelable event</h2>
<p>The below button will display whether the event is cancelable or not.</p>
<button onclick="myFunction(event)">Click me</button>
<p id="myid"></p>
<script>
function myFunction(event) {
var val = event.cancelable;
document.getElementById("myid").innerHTML = val;
}
</script>
</body>
</html>Output
Now, click on the button to display whether the event is cancelable or not. A boolean value would be returned −
