Is that possible with js keyCodes event to show an alert if the user write a determinate word? For example: the user is in homepage, write (without input) "Hello" and appear an alert like "Congratulation, you found the secret word!".
You need to bind event listener and keep track of what was typed. Basic idea
const codes = {
hello: () => console.log('hello there'),
'funky chicken': () => window.location.href = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ',
}
function hotKeyListener () {
let str = '';
let timeout;
const msDelay = 400;
window.addEventListener('keydown', function (evt) {
if (timeout) window.clearTimeout(timeout);
str += evt.key;
const action = codes[str];
if (action) {
str = '';
action();
} else {
timeout = window.setTimeout(() => str = '', msDelay);
}
});
}
hotKeyListener();
