google-chrome-app - Detect the underlying OS in a Chrome Packaged App

Question

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 ⌘</kbd>C or CtrlC accordingly.

Answer 1

您还可以使用新的chrome.runtime.getPlatformInfoAPI（https://developer.chrome.com/apps/runtime.html#method-getPlatformInfo，自Chrome 29起可用）。

Answer 2

您可以window.navigator在 JS 中使用。通常，这将包含您正在寻找的信息。可能在 window.navigator.platform 中。
