What are the JavaScript KeyCodes?
提问by Web_Designer
What keycodes are available for JavaScript? If they're not the same for all browsers, please list the keycodes for each browser.
哪些键码可用于 JavaScript？如果它们对所有浏览器都不同，请列出每个浏览器的键码。

Followed @pimvdb's advice, and created my own:

Be patient, as it takes a few seconds to generate an element for each of the 65536 characters that have a JavaScript keycode.
请耐心等待，因为为具有 JavaScript 键码的 65536 个字符中的每一个生成一个元素都需要几秒钟的时间。

keyCodes are differentfrom the ASCII values. For a complete keyCode reference, see http://unixpapa.com/js/key.html
keyCodes不同于ASCII 值。有关完整的 keyCode 参考，请参阅http://unixpapa.com/js/key.html
For example, Numpad numbers have keyCodes 96 - 105, which corresponds to the beginning of lowercase alphabet in ASCII. This could lead to problems in validating numeric input.
例如，Numpad 数字的 keyCodes 为 96 - 105，对应于 ASCII 中小写字母的开头。这可能会导致验证数字输入时出现问题。

I needed something like this for a game's control configuration UI, so I compiled a list for the standard US keyboard layout keycodes and mapped them to their respective key names.
我需要这样的东西来制作游戏的控制配置 UI，所以我为标准的美式键盘布局键码编译了一个列表，并将它们映射到它们各自的键名。
Here's a fiddle that contains a map for code -> name and visi versa: http://jsfiddle.net/vWx8V/
这是一个包含代码映射的小提琴 -> 名称，反之亦然：http: //jsfiddle.net/vWx8V/
If you want to support other key layouts you'll need to modify these maps to accommodate for them separately.
如果您想支持其他按键布局，您需要修改这些地图以分别适应它们。
That is unless you were looking for a list of keycode values that included the control characters and other special values that are not (or are rarely) possible to input using a keyboard and may be outside of the scope of the keydown/keypress/keyupevents of Javascript. Many of them are control characters or special characters like null(\0) and you most likely won't need them.
也就是说，除非你要找的键码值，其中包括控制字符和不在（或很少），可使用键盘输入，并且可以在范围之外的其他特殊值的列表keydown/ keypress/keyup的Javascript事件。其中许多是控制字符或特殊字符，例如null( \0)，您很可能不需要它们。
Notice that the number of keys on a full keyboard is less than many of the keycode values.
请注意，全键盘上的键数少于许多键码值。

This app is just awesome. It is essentially a virtual keyboard that immediately shows you the keycode pressed on a standard US keyboard.
这个应用程序太棒了。它本质上是一个虚拟键盘，可以立即向您显示在标准美式键盘上按下的键码。

One possible answer will be given when you run this snippet.
运行此代码段时将给出一个可能的答案。
document.write('<table>')
for (var i = 0; i < 250; i++) {
document.write('<tr><td>' + i + '</td><td>' + String.fromCharCode(i) + '</td></tr>')
}
document.write('</table>')td {
border: solid 1px;
padding: 1px 12px;
text-align: right;
}
table {
border-collapse: collapse;
}
* {
font-family: monospace;
font-size: 1.1em;
