Introduction

In this article I describe how to create Windows Store Apps for page transition using JavaScript. Use 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 two sections. When we navigate to a second page then the first data is shown from the first section and than data is shown from the second section of the same page.

Put the app in a Snap view to see the Snap version of this animation. The snap view is always a fixed 320px in width, which allows developers to refine and create a targeted view for this size. A width of 320px is a common and familiar size that developers are already designing for on various phone platforms. 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 three 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 two HTML pages to your project.

Write the following code in the default.html:

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8" />

    <title>App</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/script.js"></script>

    <script src="/js/default.js"></script>

</head>

<body role="application" style="background-color: darksalmon">

    <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 scenarios = [

        { url: "page.html" }

    ];

    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("App", {

        sampleTitle: sampleTitle,

        pages: pages

    });

    WinJS.Application.addEventListener("activated", activated, false);

    WinJS.Application.start();

})(); 


Write the following code in the page.html:

<!DOCTYPE html>
<
html>
<
head>
   
<title></title>
   
<script src="/js/script.js"></script>
</
head>
<
body>
   
<div id="input" data-win-control="Apps.pageInput">
       
<button id="runAnimation">Animate the page</button><br /><br />
   
</div>
   
<div id="output" data-win-control="Apps.pageOutput">
       
<p id="outputText" />
   
</div>
</
body>
</
html>

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", transitionBetweenPages, false);

            if (WinJS.Navigation.state === "sample page") {

                outputText.innerText = "Transitioned back from  page.";

                WinJS.UI.Animation.enterPage();

            }

        }

    });

    function transitionBetweenPages() {

        WinJS.UI.Animation.exitPage().done(

            function () {

                WinJS.Navigation.navigate("page1.html");

            });

    }

})(); 


Write the following code in the page1.html: 

<!DOCTYPE html>
<
html>
<
head>
   
<title></title>
   
<link rel="stylesheet" href="/css/samplePage.css" />
   
<script src="/js/scriptforpage1.js"></script>
</

<

<div id="samplePage">
       
<div id="samplePageHeader">

<div id="samplePageBody">
           
<div id="samplePageSection1">
               
<p>Hi this is Deepak Middha</p>
           
</div>
           
<div id="samplePageSection2">
               
<p>How Are you!</p>
               
<button id="returnButton">return</button>
           
</div>
       
</div>

    "use strict";

    WinJS.UI.Pages.define("Page1.html", {

        ready: function (element, options) {

            returnButton.addEventListener("click", transitionBetweenPages, false);

            rootGrid.style.overflow = "auto";

            content.style.overflow = "visible";

            WinJS.UI.Animation.enterPage([samplePageHeader, samplePageSection1, samplePageSection2], null);

        },

        unload: function () {

            rootGrid.style.overflow = "visible";

            content.style.overflow = "auto";

        }

    });

    function transitionBetweenPages() {

        WinJS.UI.Animation.exitPage([samplePageHeader, samplePageSection1, samplePageSection2], null).done(

            function () {

                WinJS.Navigation.navigate("Page.html", "sample page");

            });

    }

})(); 


Write the following code in the script1.js:
 

(function () {

    var ScenarioOutput = 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");

    var currentpageUrl = null;

    WinJS.Navigation.addEventListener("navigating", function (evt) {

    WinJS.log = function (message, tag, type) {

        var statusDiv = document.getElementById("statusMessage");

    };

    function activated(e) {
