js how to remove all event listeners code example

Example 1: javascript remove all event listeners

That is not possible without intercepting addEventListener calls and keep track of the listeners or use a library that allows such features unfortunately. It would have been if the listeners collection was accessible but the feature wasn't implemented.

The closest thing you can do is to remove all listeners by cloning the element, which will not clone the listeners collection.

Note: This will also remove listeners on element's children.

var el = document.getElementById('el-id'),
    elClone = el.cloneNode(true);

el.parentNode.replaceChild(elClone, el);

Example 2: removeeventlistener

//                             type         function
element.removeEventListener("mousedown", handleMouseDown)
