Windows Phone 8.1 SDK Preview Reveals JavaScript Support

Details about a Windows Phone 8.1 SDK preview have leaked onto reddit revealing that Microsoft plans to support javascript for programming and a universal app template for building both Windows Metro and Windows Phone apps.

The details were first posted by wpthroaway and then reposted by These after they were taken down.

Here's some of what leaked:


-----
"So I may or may not be part of the dev preview program and I might have seen that WP8.1 will support javascript for programming. Haven't seen anything yet about HTML only xaml.

The whole javascript is called a Universal App.

EDIT: yup there is html!

EDIT: universal apps is a template to build both WinStore and WinPhone apps from the same solution sharing code more easily (HTML/JScript)


EDIT: Connect portal (proof)


EDIT: WP and WinRt are categorize now under Store Apps in visual studio. So you can see how MS is trying to merge them. Main templates are universal apps that create both WP8 and WinRT project. Expecting to see more WinRT apps from now on as they're making it very easy and kind of influencing me to do so, considering the solo templates are at the bottom of the list.

EDIT: New hub app template.


EDIT: Debug my first wp8.1 app. Splashscreen is using the same box as the default one for WinRT. App has a nice transitions navigating pages (without using a 3rd party toolkit for it). Kind of like turnstile but there's something to it that makes it looks smoother.

EDIT: Screenshot of the app list

EDIT: App list: Battery sense (see what apps are taking the charge), data sense and storage sense. Oh there is a new podcast app and bings app are install by default.

EDIT: Phone app is not supported in this build. SMS not much different UI but there's some cool new settings.

EDIT: There's finally VPN support and Wifi sense.

EDIT: No cortana and bing search isn't working (button and IE). Bing.com makes the "No app for this protocol" popup, so this build doesnt have it and it also doesn't have a store.

EDIT: no more music+video. Now there is a music app that is exactly like xbox music. Same for the video app.

EDIT: skydrive is now OneDrive.

EDIT: GridView and ListView joing the WP family.

EDIT: Universal Apps are pretty cool. They share the same App object class.

EDIT: SD CARD install! But you can change the manifest to prevent your app from being install in SD.

EDIT: No more silverlight. So apps now can share XAML between WinRT and WP8 (sometimes whole pages).

EDIT: instead of an AppBard there is a commandbard. (only bottom) You can bind to the buttons.

EDIT: Tilt no longer requires a toolkit. Instead is build into most control styles using PointerDownThemeAnimation .

EDIT: Goodbye XAP hello APPX.

EDIT: Back button doesn't terminate the app. The whole life cycle is like winrt.

EDIT: Back button doesnt go back by default, instead you do this: public App() { this.InitializeComponent(); this.Suspending += OnSuspending; Windows.Phone.UI.Input.HardwareButtons.BackPressed += HardwareButtons_BackPressed; } void HardwareButtons_BackPressed(object sender, Windows.Phone.UI.Input.BackPressedEventArgs e) { Frame rootFrame = Window.Current.Content as Frame;

if (rootFrame != null) { if (rootFrame.CanGoBack) { rootFrame.GoBack(); e.Handled = true; } } }

EDIT: Navigation: this.Frame.Navigate(typeof(AboutPage));"

Microsoft is expected to publicly release an developer preview of Windows 8.1 which will feature the previously leaked action center at its Build conference in April.
