如何在UWP JavaScript应用程序中显示状态栏？

Question

How to show the Windows 10 system status bar on mobile when writing the app in JavaScript? The Windows.​UI.​View​Management.StatusBar class is not available on Mobile, or so says Visual Studio 2017.

Answer 1

You need to add the references to the UWP Mobile Extension, because the status bar only exists on Mobile.

Go to Project > Add References.

Check "Windows Mobile Extension for the UWP" and press "OK".

WARNING : You need to check if the API is present because the app can crash if it is not. Like this:

if (Windows.Foundation.Metadata.ApiInformation.isTypePresent("Windows.UI.ViewManagement.StatusBar")) {

    let statusbar = Windows.UI.ViewManagement.StatusBar.getForCurrentView();
    statusbar.showAsync();

}
