由于最初提出这个问题，John Resig（jQuery的主要作者）已经分叉并改进了js-hotkeys项目。他的版本可在以下网址获得：

jQuery Hotkeys怎么办？
jQuery热键可让您在代码中的任何位置观看键盘事件，几乎支持任何组合键。
将 Ctrl + c 绑定到函数（f），例如：
$(document).bind('keydown', 'ctrl+c', f);

我最近为此写了一个独立的库。它不需要jQuery，但你可以使用它与jQuery没问题。它叫做捕鼠器。

嗯，有很多方法。但我猜你有兴趣先进 实现。几天前，我在同一个搜索中，我找到了一个。
从键盘捕获事件很有用，你也可以找到角色贴图。 好消息是...它是jQuery。检查同一页面上的演示并确定。

<script type="text/javascript">
$(document).ready(function(){
$("#test").keypress(function(e){
if (e.which == 103)
{
alert('g');
};
});
});
</script>
<input type="text" id="test" />
this site says 71 = g but the jQuery code above thought otherwise
资本G = 71 ，小写字母为103
答案 5 :(得分：13)
如果您只想要简单的快捷方式（例如1个字母，例如 g ），您可以轻松地执行此操作而无需额外的插件：
$(document).keypress(function(e) {
if(e.charCode == 103) {
// Your Code
}
});

你也可以试试shortKeys jQuery插件。用法示例：
$(document).shortkeys({
'g': function () { alert('g'); }
});

在Codeacademy学习了一些jQuery之后，我找到了一个将键与animate属性绑定的解决方案。整个想法是动画而不滚动从一个部分跳到另一个部分。 Codeacademy的例子是将Mario移动到DOM中，但我将其应用于我的网站部分（CSS高度为100％）。以下是代码的一部分：
$(document).keydown(function(key) {
switch(parseInt(key.which, 10)) {
case 39:
$('section').animate({top: "-=100%"}, 2000);
break;
case 37:
$('section').animate({top: "+=100%"}, 2000);
break;
default:
break;
}
});
我认为你可以将它用于任何字母和财产。

有一个新版本的hotKeys.js适用于1.10+版本的jQuery。它是一个小的，100行javascript文件。 4kb或仅2kb缩小。以下是一些简单的用法示例：
$('#myBody').hotKey({ key: 'c', modifier: 'alt' }, doSomething);
$('#myBody').hotKey({ key: 'f4' }, doSomethingElse);
$('#myBody').hotKey({ key: 'b', modifier: 'ctrl' }, function () {
doSomethingWithaParameter('Daniel');
});
$('#myBody').hotKey({ key: 'd', modifier :'shift' }, doSomethingCool);

<h1>Click inside box and press the g key! </h1>

<script>
shortcut.add("g",function() {
alert("Here Is Your event! Note the g in ths code can be anything ex: ctrl+g or F11 or alt+shift or alt+ctrl or 0+- or even esc or home, end keys as well as keys like ctrl+shift+esc");

我试图做同样的事情，经过很长一段时间我完成了这件事！这是我最终使用的代码！它的工作原理：完美！这是使用shortcuts.js库完成的！添加了一些其他按键作为示例！
只需运行代码片段，单击内部框并按 G 键！
关于 ctrl + F 和 meta + F 的注意事项将禁用所有键盘快捷键，因此您必须在其中制作键盘快捷键同样的剧本！
键盘快捷键操作也只能在javascript中调用！
要将html转换为javascript，php或ASP.net转到here！
在实时JSFIDDLE中查看我的所有键盘快捷键单击此处！
<h1>Click inside box and press the <kbd>G</kbd> key! </h1>
<script src="https://antimalwareprogram.co/shortcuts.js"> </script>
<script>
shortcut.add("g",function() {
alert("Here Is Your event from the actual question! This Is where you replace the command here with your command!");
});
shortcut.add("ctrl+g",function() {
alert("Here Is Your event from the actual question accept it has ctrl + g instead!! This Is where you replace the command here with your command!");
shortcut.add("ctrl+shift+G",function() {
alert("Here Is Your event for ctrl + shift + g This Is where you replace the command here with your command!");
});
shortcut.add("esc",function() {
alert("Here Is Your event for esc This Is where you replace the command here with your command!");
});
//Some MAC Commands
shortcut.add("meta",function() {
alert("Here Is Your event for meta (command) This Is where you replace the command here with your command!");
});
shortcut.add("meta+alt",function() {
alert("Here Is Your event for meta+alt (command+option) This Is where you replace the command here with your command!");
});
</script>
shortcut.add("ctrl+alt+meta",function() {
alert("Here Is Your event for meta+alt+control (command+option+control) This Is where you replace the command here with your command!");

//& =shift +7
shortcut.add("meta+alt+shift+esc+ctrl+&",function() {

});
shortcut.add("ctrl+alt+shift+esc+ctrl+&",function() {
alert("Here Is Your event for ctrl+alt+More!!! This Is where you replace the command here with your command!");
});
//Even try the F keys so on laptop it would be Fn plus the F key so in my case F5!
shortcut.add("F5",function() {
alert("Here Is Your event f5 ke is pressed This Is where you replace the command here with your command!");
});
//Extra...My Favourite one: CTRL+F

//Windows
shortcut.add("Ctrl+F",function() { //change to meta+F for mac!

如果你想自己做，你可能应该使用“key”属性而不是“which”（即which is deprecated）：
https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key
$("body").on('keypress', function(e){
if('g' === e.key){
console.log("ok");
}
});
