Is there a way to deny location.reload call and href modification?

Question

I tried to do this:

location.reload = function() { return false }

But it seems to be denied as it still reloads the page.

EDIT

I do not want to do any harm for a user and lock it into the page. The case where I need it is - integration testing on an existing code base which has location.reload() and location.href = '...' all over the place.

Some functions are mutable, this one seems to not be one of them. Why do you need to do this? — mplungjan, Sep 04 '13 at 07:53
Locking the user to your page is not a very good idea, I would be surprised if you could coerce the browser into doing that. — Frédéric Hamidi, Sep 04 '13 at 07:53

@FrédéricHamidi I do not think that OP wants to do that. I think he has an external script that does it and he wants to block it — mplungjan, Sep 04 '13 at 07:54
You should precise your exact use case, so that it's easier to find a solution. — Denys Séguret, Sep 04 '13 at 07:54

You can use onbeforeunload

window.onbeforeunload = function () {

  return confirm("Are you sure you want to leave?");

};

However this is not supported in firefox and opera for that this may be help you

window.onbeforeunload and window.onunload is not working in Firefox , Safari , Opera?
