javascript - 虚拟键盘事件

Question

这里有没有人遇到过当是虚拟键盘且按键不是数字时不触发键盘事件的问题。在 Android 6.0.1 上运行的 Nexus 7 平板电脑会出现此问题。

$('.some.selector').on('keypress', function () {
    console.log('Pressed');
})

以上代码在以下情况下触发:单击的键是一个数字，如 0-9，如果使用其他设备，如 iPad 或 iPhone，或者如果我从 PC 远程调试我的平板电脑，那么我可以从键盘按下物理键。我在平板电脑上使用 Chrome 49 浏览器。

keypress 事件已弃用，

Chrome does not fire the keypress event for known keyboard shortcuts (reference). Which keyboard shortcuts are known depends on the user's system. Use the keydown event to implement keyboard shortcuts.

尝试使用 input 或 `keydown/keyup' 事件来代替。

注意!

The DOM input event is fired synchronously when the value of an < input> or < textarea> element is changed. Additionally, it fires on contenteditable editors when its contents are changed. In this case, the event target is the editing host element. If there are two or more elements which have contenteditable as true, "editing host" is the nearest ancestor element whose parent isn't editable. Similarly, it's also fired on root element of designMode editors.
