Introduction

In this article I describe how to create Windows Store Apps for App-Bar using JavaScript. If a command in an App-Bar requires a flyout, then one can be shown using the AppBarCommand control. When the user executes a command in a flyout off of an AppBar, then the flyout and the AppBar should both dismiss.

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 = "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/appbar-flyout.css" />

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

</head>

<body>

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

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

    </div>

    <div id="respondFlyout" data-win-control="WinJS.UI.Menu">

        <button data-win-control="WinJS.UI.MenuCommand" data-win-options="{id:'alwaysSaveMenuItem',label:'Always save drafts',type:'toggle', selected:true}">

        </button>

        <hr data-win-control="WinJS.UI.MenuCommand" data-win-options="{id:'separator',type:'separator'}" />

        <button data-win-control="WinJS.UI.MenuCommand" data-win-options="{id:'replyMenuItem',label:'Reply'}">

        <button data-win-control="WinJS.UI.MenuCommand" data-win-options="{id:'replyAllMenuItem',label:'Reply All'}">

        </button>

        <button data-win-control="WinJS.UI.MenuCommand" data-win-options="{id:'forwardMenuItem',label:'Forward'}">

        </button>

    </div>

    <div id="deleteFlyout" data-win-control="WinJS.UI.Flyout" aria-label="{Confirm delete flyout}">

        <div>

            If you delete this photo it cannot be recovered.

        </div>

        <button id="confirmDeleteButton">

            Delete Photo</button>

    </div>

    <div id="appBar" data-win-control="WinJS.UI.AppBar" data-win-options="{}">

        <button data-win-control="WinJS.UI.AppBarCommand" data-win-options="{id:'respondButton',label:'Respond',icon:'edit',type:'flyout',flyout:select('#respondFlyout')}">

        </button>

        <button data-win-control="WinJS.UI.AppBarCommand" data-win-options="{id:'deleteButton',label:'Delete',icon:'delete',type:'flyout',flyout:select('#deleteFlyout')}">

        </button>

    </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("confirmDeleteButton").addEventListener("click", confirmDelete, false);

            document.getElementById("alwaysSaveMenuItem").addEventListener("click", alwaysSave, false);

            document.getElementById("replyMenuItem").addEventListener("click", reply, false);

            document.getElementById("replyAllMenuItem").addEventListener("click", replyAll, false);

            document.getElementById("forwardMenuItem").addEventListener("click", forward, false);

            document.getElementById("appBar").addEventListener("beforeshow", clearStatus, false);

            WinJS.log && WinJS.log("To show the bar, swipe up from the bottom of the screen, right-click, or press Windows Key+Z. To dismiss the bar, tap in the application, swipe, right-click, or press Windows Logo+Z again.", "page", "status");

        },

        unload: function () {

            var appbar = document.getElementById("appBar");

            appbar.parentNode.removeChild(appbar);

        }

    });

    function hideFlyoutAndAppBar() {

        document.getElementById("respondFlyout").winControl.hide();

        document.getElementById("appBar").winControl.hide();

    }

    function confirmDelete() {

        WinJS.log && WinJS.log("You have deleted the item.", "page", "status");

        hideFlyoutAndAppBar();

    }

    function alwaysSave() {

        var alwaysSaveState = document.getElementById("alwaysSaveMenuItem").winControl.selected;

        WinJS.log && WinJS.log("The Always save option is now set to: " + alwaysSaveState + ".", "page", "status");

        hideFlyoutAndAppBar();

    }

    function reply() {

        WinJS.log && WinJS.log("You replied to the message.", "page", "status");

        hideFlyoutAndAppBar();

    }

    function replyAll() {

        WinJS.log && WinJS.log("You replied all the message.", "page", "status");

        hideFlyoutAndAppBar();

    }

    function forward() {

        WinJS.log && WinJS.log("You forwarded the message.", "page", "status");

        hideFlyoutAndAppBar();

    }

    function clearStatus() {

        WinJS.log && WinJS.log("", "page", "status");

    }

})();
