document.onkeydown = function(e) {
if(event.keyCode == 123) {
console.log('You cannot inspect Element');
return false;
}
if(e.ctrlKey && e.shiftKey && e.keyCode == 'I'.charCodeAt(0)) {
console.log('You cannot inspect Element');
return false;
}
if(e.ctrlKey && e.shiftKey && e.keyCode == 'C'.charCodeAt(0)) {
console.log('You cannot inspect Element');
return false;
}
if(e.ctrlKey && e.shiftKey && e.keyCode == 'J'.charCodeAt(0)) {
console.log('You cannot inspect Element');
return false;
