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>
<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>
<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");
}
})();
