inter-coder / disable_dev-tool.js

Last active December 23, 2022 08:53

Clearing the console alone is not enough, and a better approach is to disable the developer tool from being opened in any meaningful way

	(function() {
	'use strict';
	Object.getOwnPropertyNames(console).filter(function(property) {
	return typeof console[property] == 'function';
	}).forEach(function (verb) {
	console[verb] =function(){return 'Sorry, for security reasons...';};
	});
	window.addEventListener('devtools-opened', ()=>{
	// do some extra code if needed or ...
	// maybe even delete the page, I still like to add redirect just in case
