Removing the Event Listener on a Button programatically

Question

I have a Button which is registered with a onclick event as shown

Answer 1

You could set the onclick attribute to null.

var el = document.getElementById('inputId');
el.onclick = null;

or better just remove the attribute altogether with the removeAttribute() docs method of the element.

var el = document.getElementById('inputId');
el.removeAttribute('onclick');

you will need to add an id to the element though for this..
