Introduction
In this article I describe how to create Windows Store Apps for animation using JavaScript. Use the Page animation to bring the first page of an application onto the screen or when transitioning to a new page. The contents of the new page animates in sections. Put the app in a Snap view to see the Snap version of this animation.
I assume you can create a simple Windows Store App using JavaScript; for more help visit Simple Windows Store Apps using JavaScript.
To start the creation of the apps, add two JavaScript pages by right-clicking on the js folder in the Solution Explorer and select Add > new item > JavaScript Page and then give an appropriate name. In the same way, add a HTML page to your project.

Write the following code in the default.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>My Apps</title>
<link rel="stylesheet" href="//Microsoft.WinJS.1.0/css/ui-light.css" />
<script src="//Microsoft.WinJS.1.0/js/base.js"></script>
<script src="//Microsoft.WinJS.1.0/js/ui.js"></script>
<link rel="stylesheet" href="/sample-utils/sample-utils.css" />
<link rel="stylesheet" href="/css/default.css" />
<script src="/js/script1.js"></script>
<script src="/js/default.js"></script>
</head>
<body role="application" style="background-color: gray">
<center><div id="rootGrid">
<div id="content">
<h1 id="featureLabel"></h1>
<div id="contentHost"></div>
</div>
</div></center>
</body>
</html>
Write the following code in the default.js:
(function () {
"use strict";
var sampleTitle = "";
var Pages = [
{ url: "Page.html", title: "Show page" }
];
function activated(eventObject) {
if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {
eventObject.setPromise(WinJS.UI.processAll().then(function () {
var url = WinJS.Application.sessionState.lastUrl || Pages[0].url;
return WinJS.Navigation.navigate(url);
}));
}
}
WinJS.Navigation.addEventListener("navigated", function (eventObject) {
var url = eventObject.detail.location;
var host = document.getElementById("contentHost");
host.winControl && host.winControl.unload && host.winControl.unload();
WinJS.Utilities.empty(host);
eventObject.detail.setPromise(WinJS.UI.Pages.render(url, host, eventObject.detail.state).then(function () {
WinJS.Application.sessionState.lastUrl = url;
}));
});
WinJS.Namespace.define("Apps", {
sampleTitle: sampleTitle,
Pages: Pages
});
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Application.start();
})();
Write the following code in the page.html:
(function () {
"use strict";
var sampleTitle = "";
var Pages = [
{ url: "Page.html", title: "Show page" }
];
function activated(eventObject) {
if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {
eventObject.setPromise(WinJS.UI.processAll().then(function () {
var url = WinJS.Application.sessionState.lastUrl || Pages[0].url;
return WinJS.Navigation.navigate(url);
}));
}
}
WinJS.Navigation.addEventListener("navigated", function (eventObject) {
var url = eventObject.detail.location;
var host = document.getElementById("contentHost");
host.winControl && host.winControl.unload && host.winControl.unload();
WinJS.Utilities.empty(host);
eventObject.detail.setPromise(WinJS.UI.Pages.render(url, host, eventObject.detail.state).then(function () {
WinJS.Application.sessionState.lastUrl = url;
}));
});
WinJS.Namespace.define("Apps", {
sampleTitle: sampleTitle,
Pages: Pages
});
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Application.start();
})();
Write the following code in the script.js:
(function () {
"use strict";
var page = WinJS.UI.Pages.define("Page.html", {
ready: function (element, options) {
runAnimation.addEventListener("click", runEnterPageAnimation, false);
}
});
function runEnterPageAnimation() {
var pageSections = pageSectionsControl.value;
content.style.overflow = "hidden";
var enterPage;
switch (pageSections) {
case "1":
enterPage = WinJS.UI.Animation.enterPage(rootGrid, null);
break;
case "2":
enterPage = WinJS.UI.Animation.enterPage(rootGrid, null);
break;
case "3":
enterPage = WinJS.UI.Animation.enterPage(rootGrid, null);
break;
}
outputText.innerText = "Animation Appeared inH" + pageSections + " section(s).";
}
})();
Write the following code in the script1.js:
(function () {
var PageOutput = WinJS.Class.define(
function (element, options) {
element.winControl = this;
this.element = element;
new WinJS.Utilities.QueryCollection(element)
.setAttribute("role", "region")
.setAttribute("aria-labelledby", "outputLabel")
.setAttribute("aria-live", "assertive");
element.id = "output";
this._addOutputLabel(element);
this._addStatusOutput(element);
}, {
_addOutputLabel: function (element) {
var label = document.createElement("h2");
label.id = "outputLabel";
label.textContent = "";
element.parentNode.insertBefore(label, element);
},
_addStatusOutput: function (element) {
var statusDiv = document.createElement("div");
statusDiv.id = "statusMessage";
element.insertBefore(statusDiv, element.childNodes[0]);
}
}
);
var currentPageUrl = null;
WinJS.Navigation.addEventListener("navigating", function (evt) {
currentPageUrl = evt.detail.location;
});
WinJS.log = function (message, tag, type) {
var isError = (type === "error");
var isStatus = (type === "status");
var statusDiv = document.getElementById("statusMessage");
};
function activated(e) {
WinJS.Utilities.query("#featureLabel")[0].textContent = Apps.sampleTitle;
}
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Namespace.define("Apps", {
PageOutput: PageOutput
});
})();
