Remove Event Handlers Using jQuery
Once an event handler is established, it remains in effect for the remainder of the life of the page. There may be a need when you would like to remove event handler.
jQuery provides the unbind() command to remove an exiting event handler. The syntax of unbind() is as follows.
The following is the description of the parameters −
- eventType − A string containing a JavaScript event type, such as click or submit. Refer to the next section for a complete list of event types.
- handler − If provided, identifies the specific listener that's to be removed.
Example
You can try to run the following code to learn how to remove event handlers using jQuery −
<html>
<head>
<title>jQuery Unbind</title>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script>
$(document).ready(function() {
function aClick() {
$("div").show().fadeOut("slow");
}
$("#bind").click(function () {
$("#theone").click(aClick).text("Can Click!");
});

$("#theone").unbind('click', aClick).text("Does nothing...");
});
});
