Text Formatting Windows Store Apps

By Deepak Middha on Dec 05, 2012
In this article I described how to create a Windows Store App for Formatting Text using JavaScript.

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.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/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">

            Deepak Arora.

        </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>

            <option value="blue">Blue</option>

            <option value="purple">Purple</option>

        </select>

        <br />

        <label for="textSize">

            Size</label>

        <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";

    }

})();
