KeyboardEvent.keyCode

您正在阅读此内容的英文版本,因为该语系尚未翻译。 帮助我们翻译此文章吧!

该功能已从Web标准中删除。 尽管一些浏览器可能仍然支持它,但它正在被丢弃。 避免使用它并尽可能更新现有的代码; 请参阅本页底部的兼容性表格来指导您的决定。 请注意,此功能可能随时停止工作。

这个只读的属性 KeyboardEvent.keyCode 代表着一个唯一标识的所按下的键的未修改值,它依据于一个系统和实现相关的数字代码。这通常是与密钥对应的二进制的ASCII (RFC 20)和Windows 1252 码。如果这个键不能被标志,这个值为0。

keypress事件的值在各个浏览器中不尽相同。 IE 和Google Chrome 设置 KeyboardEvent.charCode 。如果按下的键是可打印键,则Gecko设置为0,否则它将keyDownkeyUp事件设置为相同的keyCode。

你应该尽量避免使用它; 它已经被弃用了一段时间. 相反的, 你应该使用KeyboardEvent.code,如果它在你的浏览器中被实现了的话。 不幸的是,有一些浏览器还是没有实现它,所以你在使用之前必须要小心,确认你所使用的那个被所有目标浏览器所支持。.Google Chrome 和Safari 实现了KeyboardEvent.keyIdentifier, 虽然这是在规范草案中被实现的,而不是最终规范。

在处理keydown和keyup事件时,Web开发人员不应使用可打印字符的keycode属性。如上所述,keycode属性对可打印字符不有用,尤其是那些按下shift或alt键的输入。在实现快捷键处理程序时,事件(“keypress”)事件通常更好(至少当gecko是正在使用的运行时)。详情请参见Gecko按键事件.

Example

window.addEventListener("keydown", function (event) {
  if (event.defaultPrevented) {
    return; // 如果已取消默认操作,则不应执行任何操作
  }

  var handled = false;
  if (event.key !== undefined) {
    // 使用keyboardvent.key处理事件,并将handled设置为true。
  } else if (event.keyIdentifier !== undefined) {
    // 使用keyboardvent.keyIdentifier处理事件,并将handled设置为true。
  } else if (event.keyCode !== undefined) {
    //使用keyboardvent.keycode处理事件并将handled设置为true。
  }

  if (handled) {
    // 如果事件已处理,则禁止“双重操作”
    event.preventDefault();
  }
}, true);

键码值

标准位置的可打印键

 

 

在标准位置按下或释放可打印键导致的按键事件值在浏览器之间不兼容。
IE只将本机虚拟密钥代码值公开为keyboardvent.keycode。
Google Chrome、Chromium和Safari必须根据输入字符确定值。如果输入字符可以用US键盘布局输入,则使用US键盘布局上的keycode值。
从gecko 15 geckore lease(“15.0”)开始,gecko从一个可由键输入的ASCII字符(即使具有移位修饰符或支持ASCII的键盘布局)决定键码值。有关详细信息,请参见以下规则:

  1. 如果系统是Windows,并且按下键的本机键代码指示键是A-Z或0-9,请使用键代码。
  2. 如果系统是Mac,并且按下键的本机键码指示键为0-9,则使用键码。
  3. 如果按下键输入一个ASCII字母或数字,没有修改键,请使用键码。
  4. 如果按下键输入带SHIFT键的ASCII字母或数字,请使用键代码。
  5. 如果按下键输入另一个没有修改键的ASCII字符,请使用键码。
  6. 如果按下键输入另一个带SHIFT键的ASCII字符,请使用键码。
  7. 否则,即按下键输入一个Unicode字符:
  • 如果键盘布局是支持ASCII的键盘布局(即,可以输入ASCII字母),则使用0。
  • 否则,即键盘布局不支持ASCII,使用环境中安装的具有最高优先级的支持ASCII的键盘布局:
    • 如果按备用键盘布局上的键输入一个ASCII字母或数字,请使用键代码。
    • 否则,使用0。

Windows上的OEM特定密钥

在Windows上,虚拟密钥代码的某些值是为特定于OEM的密钥定义(保留)的。它们可用于非标准键盘上的特殊键。换句话说,一些值被两个或多个供应商(或硬件)用于不同的含义。

 

从gecko 21(并且早于15)开始,仅在Windows上的keycode属性上提供OEM特定的键值。因此,它们对于通常的Web应用程序不有用。它们仅对内部网应用程序或类似情况有用。
