Transition Between Pages in Windows Store Apps

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>

</head>

</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>
</head>
<body>
<div id="samplePage">
<div id="samplePageHeader">
</div>
<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>
</div>
</body>
</html>

Write the following code in the scriptforpage1.js:

(function () {

"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");

label.id = "outputLabel";

label.textContent = "Output";

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 statusDiv = document.getElementById("statusMessage");

};

function activated(e) {

WinJS.Utilities.query("#featureLabel")[0].textContent = SdkSample.sampleTitle;

}

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

WinJS.Namespace.define("Apps", {

pageOutput: pageOutput

});

})();

Output
