Use the jQuery off() Method

You can simply use the jQuery off() method to remove the event handlers that were attached with on(). Don't use the unbind() method, it has been deprecated since jQuery 3.0.

If you try out the following example, you'll find the event handler function sayHello() is not executing for the button element having the id btnOff:

<!DOCTYPE html>
<html lang="en">
<head>
<title>jQuery Remove Event Handler</title>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
function sayHello(){
    alert("Hello, World!");
}
$(document).ready(function(){
    // Attach an event handler function to click event
    $("#btnOn, #btnOff").on("click", sayHello);
 
    // Removes the click event handler from second button
    $("#btnOff").off("click");
});
</script>
</head>
<body>
    <button type="button" id="btnOn">Click On</button>
    <button type="button" id="btnOff">Click Off</button>
</body>
</html>
