Removing Event Handlers in JavaScript
var obj = document.getElementById("div1"); obj.addEventListener('click', clickHandler); . . . obj.removeEventListener('click', clickHandler);
You can also remove event handlers from the event using the removeEventListener() function on the DOM object. You need to specify the event type and the name of the event handler to remove. For example, the following code adds an event handler and then removes it:
function clickHandler(e){ . . . } var obj = document.getElementById("div1"); obj.addEventListener('click', clickHandler);
