我在这里有一个名为的按钮.togglePL，并对其进行了编码以展开或折叠 中的页面选择器#pageList。我想使用键盘元素展开或折叠页面选择器，而alt + p无需单击按钮本身。我尝试过研究如何通过在线 JS 和此处的问题来做到这一点，但没有成功。请查找随附的代码，任何帮助将不胜感激。谢谢。// Toggle Page List$(document).ready(function() { $('.togglePL').click(function(e) { if ($('#pageList').width() == 40) { $('.textPL').show(); $('#pageList').width(168); $('.togglePL').css({left:'192px', transform: 'none'}); $('#pageList a').css({fontSize:'10pt'}); } else { $('.textPL').hide(); $('#pageList').width(40); $('.togglePL').css({left:'64px', transform: 'rotate(180deg)', transitionDuration:'0.3s'}); $('#pageList a').css({fontSize:'14pt'}); } });});<!doctype html><!-- ~ Copyright (c) Summit Learning Management System (made by students, for students). 2020.--><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0"> <title>Welcome - Summit</title> <script src="https://kit.fontawesome.com/bec3ffe91b.js" crossorigin="anonymous"></script> <!-- External Font Stylesheet --> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> <!-- External JQuery Script --> <link rel="stylesheet" type="text/css" href="../CSS/setting.css"> <!-- Internal Stylesheet --> <link rel="stylesheet" type="text/css" href="../CSS/styling.css"> <!-- Internal Stylesheet --> <link rel="shortcut icon" href="#"> <!-- Favicon --> </head> <body>

你可以这样做。在按键事件上检查是否keycode为 80 并altkey按下。然后触发菜单的单击事件
if (e.altKey && keyCode == 80)
代码
// Toggle Page List
$(document).ready(function() {
$('.togglePL').click(function(e) {
if ($('#pageList').width() == 40) {
$('.textPL').show();
$('#pageList').width(168);
$('.togglePL').css({left:'192px', transform: 'none'});
$('#pageList a').css({fontSize:'10pt'});
}
else {
$('.textPL').hide();
$('#pageList').width(40);
$('.togglePL').css({left:'64px', transform: 'rotate(180deg)', transitionDuration:'0.3s'});
$('#pageList a').css({fontSize:'14pt'});
}
});
});
$(document).on('keydown', function (e) {
let keyCode = e.keyCode | e.which;
if (e.altKey && keyCode == 80) {
$('.togglePL').trigger('click')
}
})
