<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>App6</title>
<!-- WinJS references -->
<link href="WinJS/css/ui-dark.css" rel="stylesheet" />
<script src="WinJS/js/base.js"></script>
<script src="WinJS/js/ui.js"></script>
<!-- App6 references -->
<link href="/css/default.css" rel="stylesheet" />
<script src="/js/default.js"></script>
</head>
<body class="win-type-body" onload="alert('oh yeah');">
</body>
</html>

The alert function is not supported in UWP app context. You have to use
var dialog = new Windows.UI.Popups.MessageDialog("Hello");
dialog.showAsync();
