Block the esc key

[fucker300]

I have a problem using memos. When modifying the interface of existing memos, pressing the exit key will cancel the editing and return to the original interface. I want to prevent the exit

document.addEventListener('keydown', function(event) {
if (event.keyCode === 27) {
event.preventDefault();
// event.stopPropagation();
event.stopImmediatePropagation();
alert('ESC key has been disabled');
} }, true);

It can be partially blocked.,Press esc when you enter chinese pinyin or it will quit.,Is there a way to fully organize it by JavaScript code?
tks!
