Rewriting the global alert() function doesn't work in Tampermonkey

In Greasemonkey I can rewrite the global alert() function with:

window.alert = function() {}

and it works anywhere.
But, in Tampermonkey (Chrome), it only works on it's own script.

Why? And could I make it work globally?

Hi,

You must use unsafeWindow.alert = function () {};

Hi,

that contains the alert that you want to replace, and what you want to inject code instead

§

try

unsafeWindow.alert = function(){return false};
window.alert = function(){return false};
Window.prototype.alert = function(){return false};

Thanks but that didn't work

// ==UserScript==
// @name Block
// @namespace
// @description
// @include *
// ==/UserScript==

unsafeWindow.alert = function(){return false};
window.alert = function(){return false};
Window.prototype.alert = function(){return false};

Hi,

Try this


// ==UserScript==
// @name Stop Alert Box
// @namespace stopalertbox
// @version 1.0
// @description Stop Alert Box
// @match http://*/*
// @copyright 2014+, Reek
// @run-at document-start
// ==/UserScript==


unsafeWindow.alert = function(){return false};
window.alert = function(){return false};
Window.prototype.alert = function(){return false};

Maybe Chrome doesn't allow redefining it.

If your @grant is none, use window.alert = null, otherwise use unsafeWindow.alert = null;.

// ==UserScript==
// @name         Disable alert
// @namespace    org.gf.860
// @version      0.1
// @description  Disable window.alert 
// @author       You
// @include      *
// @run-at       document-start
// @grant        none
// ==/UserScript==

window.alert = null;
