Detect the underlying OS in a Chrome Packaged App

问题

Since packaged apps can run on different platforms, is there any way to distinguish between Windows and Mac ?

I would like to show some help vis-à-vis keyboard shortcuts and being able to detect the OS would help in for example showing Command ⌘C or CtrlC accordingly.

回答1:

You can use window.navigator in JS. Typically that will have the information you're looking for. Probably in window.navigator.platform.

回答2:

You can also use the new chrome.runtime.getPlatformInfo API (https://developer.chrome.com/apps/runtime.html#method-getPlatformInfo, available since Chrome 29).
