Introduction
In this article I describe how to create Windows Store Apps for formatting text using JavaScript. If there are a small number of settings contextual to a particular object in the app rather than the app itself, then use a fly-out to commit those settings. Changes should be reflected as soon as the user makes a change.
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.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>

<title></title>
<link rel="stylesheet" href="/css/change-settings.css" />
<script src="/js/script.js"></script>
</head>
<body>
<div data-win-control="App.pageInput">
<p>
Click the "change color" button to launch the output.
</p>
<button id="formatTextButton" class="action">
Change Color</button>
</div>
<div data-win-control="App.pageOutput">
<p id="outputText">

</p>
</div>
<div id="formatTextFlyout" data-win-control="WinJS.UI.Flyout" aria-label="{Format text flyout}">
<label for="textColor">
Text color</label>
<br />
<select id="textColor">
<option value="black">Black</option>
<option value="red">Red</option>
<option value="green">Green</option>

<br />
<input type="range" id="textSize" min="6" max="75" value="11" />
</div>
</body>
</html>
Write the following code in the default.html:
(function () {
"use strict";
var page = WinJS.UI.Pages.define("page.html", {
ready: function (element, options) {
document.getElementById("formatTextButton").addEventListener("click", showFormatTextFlyout, false);
document.getElementById("textColor").addEventListener("change", changeColor, false);
document.getElementById("textSize").addEventListener("change", changeSize, false);
}
});
function showFormatTextFlyout() {
var formatTextButton = document.getElementById("formatTextButton");
document.getElementById("formatTextFlyout").winControl.show(formatTextButton);
}
function changeColor() {
document.getElementById("outputText").style.color = document.getElementById("textColor").value;
}
function changeSize() {
document.getElementById("outputText").style.fontSize = document.getElementById("textSize").value + "pt";
}
})();
