浏览器之外的关键事件？

[英]Key events outside the browser?

原文 2012-02-02 21:43:47 6 1 javascript/ dom-events

I couldn't resolve this on Google, but is it possible to register key events happening outside the browser?我无法在 Google 上解决这个问题，但是是否可以注册在浏览器之外发生的关键事件？ Reason why is I got a new G19 gaming keyboard.我得到一个新的 G19 游戏键盘的原因。 It has a 5-inch LCD screen on which I use LCDHOST to show an HTML file on screen.它有一个 5 英寸的 LCD 屏幕，我使用 LCDHOST 在屏幕上显示一个 HTML 文件。

My issue here is that I wish to use JavaScript to detect key events so I can show different things when I'm in a game.我的问题是我希望使用 JavaScript 来检测关键事件，这样我在玩游戏时就可以显示不同的东西。

The HTML and JavaScript is local at my machine. HTML 和 JavaScript 在我的机器上是本地的。
