javascriptを使用してWindows 8アプリで作業しています
javaScript を使用して拡張スプラッシュ スクリーンを作成する方法については、MSDN のチュートリアルを参照してください。拡張スプラッシュ スクリーンは正常に動作します。しかし、それを削除してアプリを起動することはできません。助けてくれてありがとう。
これは私のdefaulf.jsファイルです。

最後に、splash.htmlファイルがあります。
<div id="extendedSplashScreen" class="extendedSplashScreen hidden">
<img id="extendedSplashImage" src="/images/splash-sdk.png" alt="Splash screen image" />
<!-- Optionally, add a progress ring. Note: In this sample, the progress ring is not used. -->
<!--
<progress id="extendedSplashProgress" style="color: white;" class="win-medium win-ring"></progress>
-->
<div id="extendedSplashDescription">
<span id="extendedSplashText">The splash screen was dismissed and the image above was positioned using the splash screen API.</span>
<br /><br />
<button class="action" id="learnMore">Learn More</button>
</div>
</div>
例を教えてください、または私を案内してください... どうもありがとうございました。スタートページをsplash.htmlに変更すると正常に動作しますが、アプリはdefault.htmlで正常に動作します
