- jQuery - how to remove event with
offmethod? - introduced in jQuery 1.7 - jQuery - how to remove event with
unbindmethod? - deprecated since jQuerry 3.0
2. Removing handler with removeAttr method examples
This approach is useful when an event has been added as an element attribute (e.g. onclick).
2.1. When the event has been added in HTML
// ONLINE-RUNNER:browser;
<!doctype html>
<html>
<head>
<script>
function onClick() {
console.log('Event name: click');
}
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.js"></script>
</head>
<body>
<button id="my-button" onclick="onClick();">
Click button...
</button>
<br /><br />
<button id="my-cleaner">
Remove click event...
</button>
<script>
$(document).ready(function() {
var button = $('#my-button');
$('#my-cleaner').on('click', function() {
button.removeAttr('onclick'); // removing event attribute
})
});
</script>
</body>
</html>
2.2. When the event has been added in JavaScript
// ONLINE-RUNNER:browser;
<!doctype html>
<html>
<head>
<script>
function onClick() {
console.log('Event name: click');
}
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.js"></script>
</head>
<body>
<button id="my-button" onclick="onClick();">
Click button...
</button>
<br /><br />
<button id="my-cleaner">
Remove click event...
</button>
<script>
$(document).ready(function() {
var button = $('#my-button');
button.prop('onclick', function() {
return onClick;
});
$('#my-cleaner').on('click', function() {
button.removeAttr('onclick'); // removing event attribute
})
});
</script>
</body>
</html>
3. Removing handler with prop method example
This approach is useful when an event has been added as an element property (e.g. onclick).
// ONLINE-RUNNER:browser;
<!doctype html>
<html>
<head>
<script>
function onClick() {
console.log('Event name: click');
}
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.js"></script>
</head>
<body>
<button id="my-button">
Click button...
</button>
<br /><br />
<button id="my-cleaner">
Remove click event...
</button>
<script>
$(document).ready(function() {
var button = $('#my-button');
button.prop('onclick', function() {
return onClick;
});
$('#my-cleaner').on('click', function() {
button.prop('onclick', null); // removing event property
})
});
</script>
</body>
</html>
