javascript - Prevent page loading

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 should use some flag to check if page is editing values or just navigating to other page

you can follow this thread too Javascript, controlling an onbeforeunload tag

To unbind the event, set it to null:

window.onbeforeunload = null;

It may however be better for program flow to put a condition inside your onbeforeunload handler, so that you have a single function running on page unload:

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

You set the handler to null:

window.onbeforeunload = null;
