Introduction

In this article I describe how to create Windows Store Apps for formatting text using JavaScript. When there is more information about an object than you want to show in context, put it in a flyout. If the user requires more context to understand the content of the flyout, use a title to add context.

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 one JavaScript page by right-clicking on the js folder in the Solution Explorer and select Add > new item > JavaScript Page and then provide 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></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="/css/default.css" />

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

</head>

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

<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 appTitle = "Flyout control app";

var pages = [

{ 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", {

appTitle: appTitle,

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>

<link rel="stylesheet" href="/css/provide-information.css" />

<script src="/js/provide-information.js"></script>

</head>

<body>

<div data-win-control="APP.pageInput">

<a href="#" id="moreInfoLink">Lorem ipsum

</div>

<div data-win-control="APP.pageOutput">

</div>

<div id="moreInfoFlyout" data-win-control="WinJS.UI.Flyout" aria-label="{More info flyout}">

<div class="win-type-x-large">

Lorem Ipsum

</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) {

document.getElementById("moreInfoLink").addEventListener("click", showMoreInfoFlyout, false);

document.getElementById("moreInfoFlyout").addEventListener("afterhide", onDismiss, false);

}

});

function showMoreInfoFlyout() {

WinJS.log && WinJS.log("The flyout was shown.", "app", "status");

var moreInfoLink = document.getElementById("moreInfoLink");

document.getElementById("moreInfoFlyout").winControl.show(moreInfoLink);

}

function onDismiss() {

WinJS.log && WinJS.log("The flyout was dismissed.", "app", "status");

}

})();
