1. Dedicated approaches:

  1. jQuery - how to remove event with off method? - introduced in jQuery 1.7
  2. jQuery - how to remove event with unbind method? - 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>
