如何在JavaScript中检测macOS命令键

Question

How can I know macOS command keys in JavaScript.

Need to know left and right command keys. I know key codes of these both but I don't know how to separate from other keys.

Answer 1

See the snippet below

 $(window).keydown(function (e){ if (e.metaKey) { alert('meta key is pressed'); } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 

Answer 2

You could look on keydown/keyup and record when a key is pressed based on event.keyCode .

Or as Alexander pointed out, you can also use:

event.metaKey https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/metaKey

There are some libraries which can help you out as these keys are browser dependent
