jQuery off() Method

The off() method in jQuery is used to remove event handlers attached with the on() method.

Syntax

The syntax is as follows −

$(selector).off(event,selector,function(eventOb),map)

Above, the event parameter specifies one or more events or namespaces to remove from the selected element(s), function(eventOb) is the function to run when the event occurs. The map parameter is the event map.

Example

Let us now see an example to implement the jQuery off() method −

 Live Demo

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
   $(document).ready(function(){
      $("p").on("click", function(){
         $(this).css("font-size", "1.5em");
      });
      $("button").click(function(){
         $("p").off("click");
      });
   });
</script>
</head>
<body>
<h2>Demo Heading</h2>
<p>Click here to change the font size</p>
<button>Remove</button>
</body>
</html>
