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");
}
})();
