js代码，同时按下t和u键时，输出网页标题和网址。
let keys = {}; document.addEventListener(‘keydown’, (event) ⇒ { keys[event.key] = true;
if(keys[‘t’] && keys[‘u’]) { console.log(“网页标题：” + document.title); console.log(“网页地址：” + window.location.href);
// 可以根据需求进行进一步操作，比如将信息显示在页面上
} });
document.addEventListener(‘keyup’, (event) ⇒ { delete keys[event.key]; });

js代码，按下Alt+任意按键，显示该组合键的字码和所按下的字符
document.addEventListener(‘keydown’, function(event) { if (event.altKey) { console.log(‘Alt key is pressed’); console.log(‘Key code: ’ + event.keyCode); console.log(‘Character pressed: ’ + String.fromCharCode(event.keyCode)); } });
那怎么才能判断按下的是a还是Alt+a
let altPressed = false;
document.addEventListener(‘keydown’, function(event) { if (event.key === “Alt”) { altPressed = true; } else if (altPressed && event.key === “a”) { console.log(“You pressed Alt+a”); } else { altPressed = false; } });
document.addEventListener(‘keyup’, function(event) { if (event.key === “Alt”) { altPressed = false; } });
