How to check if event exists on element in jQuery?
To check if event exists on element in jQuery, check for the existing events on the element.
Here, I have set the div −
<div id="demo"> This is demo text. Click here! </div>
When you click div, then the alert generates which I have set using the div id:
$("#demo").click(function() { alert("Does event exists? - "+hasEvents); });
You can try to run the following code to check if event exists −
Example
<!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("#demo").click(function() { alert("Does event exists? - "+hasEvents); }); var events = $._data(document.getElementById('demo'), "events"); var hasEvents = (events != null); }); </script> </head> <body> <div id="demo">This is demo text. Click here!</div> </body> </html>
