I think that the fastest way to do this is to just clone the node, which will remove all event listeners:

var old_element = document.getElementById("btn");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);

Just be careful, as this will also clear event listeners on all child elements of the node in question, so if you want to preserve that you'll have to resort to explicitly removing listeners one at a time.

Here s a function that is also based on cloneNode  but with an option to clone only the parent node and move all the children  to preserve their event listeners    function recreateNode el  withChildren      if  withChildren        el parentNode replaceChild el cloneNode true   el         else       var newEl   el cloneNode false       while  el hasChildNodes    newEl appendChild el firstChild       el parentNode replaceChild newEl  el           Remove event listeners on one element   recreateNode document getElementById  btn       Remove event listeners on an element and all of its children   recreateNode document getElementById  list    true       If you need to keep the object itself and therefore can t use cloneNode  then you have to wrap the addEventListener function and track the listener list by yourself  like in this answer
