Question

I want to prevent the page loading when “Editing” on m page occures.

so i got this code

window.onbeforeunload = function() {
  return "Are you sure you want to navigate away?";
}

Now i need to unbind this from the page.

is there any methods available ?

Thank you.

You set the handler to null:

window.onbeforeunload = null;
