mac book中js如何识别command键
通过JavaScript如何识别Mac/Apple key 呢?
Unlike Shift/Alt/Ctrl, Mac/Apple key is not considered as a modifier key--instead, you should hook on keydown/keyup and record when a key is pressed and then depressed based on event.keyCode.
不幸的是,这些key code是依赖浏览器的:
Firefox: 224
Opera: 17
WebKit (Safari/Chrome): 91 (Left Apple) or 93 (Right Apple)
