我正在开发一个网络应用程序，我想覆盖 CTRL+N (windows) CMD+N (mac) 快捷方式，这样它们就不会打开新窗口。我希望触发自定义事件。
$(window).bind( 'keydown', function(e) {
if(e.ctrlKey && e.keyCode === 'N'.charCodeAt(0)){
e.preventDefault();
// custom trigger
}
});
感谢您的帮助！

请试试这个
<script>
window.addEventListener('keyup', function(e) {
if (e.keyCode === KeyCode.KEY_RETURN) {
console.log('It was the Return key.');
} else {
console.log('It was any other key.');
}
});
<script>
