How can I disable javascript popups/alerts in Chrome?
Solution 1
The only way to disable the alert boxes is to install either an extension or a userscript. The userscript you linked is for Firefox Greasemonkey and will not work on Chrome.
Additionally, the misbehaving page you cite is sneaky and runs that "word validator" in an iframe
with code that fires the alert()
immediately upon iframe reload.
But here's a userscript that defeats it:
// ==UserScript==
// @name Wordswithfriends, Block javascript alerts
// @match http://wordswithfriends.net/*
// @run-at document-start
// ==/UserScript==
addJS_Node (null, null, overrideSelectNativeJS_Functions);
function overrideSelectNativeJS_Functions () {
window.alert = function alert (message) {
console.log (message);
}
}
function addJS_Node (text, s_URL, funcToRun) {
var D = document;
var scriptNode = D.createElement ('script');
scriptNode.type = "text/javascript";
if (text) scriptNode.textContent = text;
if (s_URL) scriptNode.src = s_URL;
if (funcToRun) scriptNode.textContent = '(' + funcToRun.toString() + ')()';
var targ = D.getElementsByTagName ('head')[0] || D.body || D.documentElement;
targ.appendChild (scriptNode);
}
If you really want to disable ALL alerts()
on ALL pages (Not recommended), then delete the // @match
line.
Solution 2
There is at least one extension for that in the Chrome Web Store. Works for me, even though it sounds a bit suspect that it has an optional support by ads mode you can disable in its settings page. (I didn't find the setting, but figured it couldn't hurt null routing api.s13.us
.)

Sorry if it's been asked. I've already found several solutions that aren't working. Not sure what I'm doing wrong.
I don't want to disable all javascript, only Javascript alert boxes. The ones that pop up and force you to click OK or X to close them.
I've found user scripts that claim to do this (example: http://userscripts.org/scripts/show/58252 ). I've put chrome on the dev channel, start chrome with the --enable-user-scripts switch, the script shows up as installed.
But I still get the alert boxes.
An example alert box that isn't getting disabled is at http://wordswithfriends.net/ - put in any garbage word into the word validator on the right sidebar. You get a popup telling you it's not a word.

CreeDorofl about 7 yearsthis sounds interesting, as annoying error popups would be nice to remove in general. Does it let you specify exactly what sort of dialogues you want to automatically OK/cancel, or does it somehow choose them by itself?

Serhiy about 7 yearsYes, you can specify what dialogues to close and the button to click.

arket about 7 yearsWhy is not recommended to disable all alerts? I never came accross useful alerts except "do you really want to exit this tab" on unsaved progress pages.

Brock Adams over 5 years@riv, open a new question if you have a case where it doesn't work. Be sure to provide a complete recipe for duplicating the problem.
