JavaScript keyboard shortcuts for web application
提问by Achim
I want to develop a web application, which should (ideally) be fully usable via the keyboard. I know how to handle keyboard events in JavaScript, but managing them for a larger application is quite boring.
我想开发一个 Web 应用程序，它应该（理想情况下）可以通过键盘完全使用。我知道如何在 JavaScript 中处理键盘事件，但是为更大的应用程序管理它们是很无聊的。
Is there a library which makes that process easier?
有没有一个图书馆可以让这个过程更容易？
Please note that I'm not interested in a full-blown Web GUI framework. I want to keep control over my webpage/application.
请注意，我对成熟的 Web GUI 框架不感兴趣。我想控制我的网页/应用程序。

You could start by reading about the accesskeyattribute:
您可以先阅读有关accesskey属性的信息：
This attribute assigns an access key to an element. An access key is a single character from the document character set. Note. Authors should consider the input method of the expected reader when specifying an accesskey.
[...]
The invocation of access keys depends on the underlying system. For instance, on machines running MS Windows, one generally has to press the "alt" key in addition to the access key. On Apple systems, one generally has to press the "cmd" key in addition to the access key.
此属性为元素分配访问键。访问键是文档字符集中的单个字符。笔记。作者在指定访问键时应考虑预期读者的输入法。
[...]
访问密钥的调用取决于底层系统。例如，在运行 MS Windows 的机器上，除了访问键之外，通常还必须按下“alt”键。在 Apple 系统上，除了访问键之外，通常还必须按“cmd”键。
You can also put the accesskeyattribute on <a>elements, an example of this usage can be found on the "Random Article" sidebar link on Wikipedia.
您还可以将accesskey属性放在<a>元素上，可以在Wikipedia上的“随机文章”侧边栏链接中找到这种用法的示例。

I would strongly encourage you to check out Thomas Fuchs' keymaster for doing keyboard shortcuts in web applications: https://github.com/madrobby/keymaster
我强烈建议您查看 Thomas Fuchs 的 keymaster 以在 Web 应用程序中使用键盘快捷键：https: //github.com/madrobby/keymaster
It makes it quite simple:
它使它变得非常简单：
// Define short of 'a'
key('a', function(){ alert('you pressed a!') });
// Returning false stops the event and prevents default browser events
key('ctrl+r', function(){ alert('stopped reload!'); return false });
// Multiple shortcuts that do the same thing
key('?+r, ctrl+r', function(){ });

You could use the accesskeyHTML attribute as it would then make your web application accessible.
您可以使用accesskeyHTML 属性，因为它可以使您的 Web 应用程序可访问。
Use the KeyTipsjQuery Plugin to display them to the user in a similar way to Office Ribbon keyboard shortcuts.
使用KeyTipsjQuery 插件以类似于Office 功能区键盘快捷键的方式向用户显示它们。
Note that the Wikipedia page on accesskeylists the modifier keys to invoke access keys for different browsers.
请注意，有关 accesskey 的维基百科页面列出了为不同浏览器调用访问键的修饰键。
