Page Animation in Windows Store Apps Using JavaScript

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>

</head>

</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

});

})();

Output
