Question

I would like to cancel every event handler defined in a page with JavaScript. In other words, if the page previously set up many event listeners on many different DOM levels, this method would simply delete every one of them. Is there a way to do this in JavaScript?

Answer 1

For clearing all the events dynamically attached to elements within the body of the page, you can do:

document.body.innerHTML = document.body.innerHTML;

For clearing events attached to the window object, you can do:

window.onscroll = function() {};

and so on..
