Action Confirmation Windows Store Apps

By Deepak Middha on Dec 03, 2012
In this article I describe how to create Windows Store Apps for confirmation of an action using JavaScript.

Introduction

In this article I describe how to create Windows Store Apps for confirmation of an action using JavaScript. When the user is about to take a drastic action that shouldn't be taken accidentally, inform the user of the consequence(s) of taking this action in a fly-out to provide an opportunity for the user to avoid completing the action.

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: lightcoral">

    <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 = "";

    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/confirm-action.css" />

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

</head>

<body>

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

 

        <p>

            Click the 'Buy' button to launch the purchase confirmation flyout.

        </p>

        <button class="action" id="buyButton">

            Buy</button>

        <br />

        <br />

    </div>

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

    </div>

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

        <div>

            Your account will be charged 1000rs.

        </div>

 

        <button id="confirmButton">

            Complete Order</button>

    </div>

</body>

</html>


Write the following code in the script.js:
 

(function () {

    "use strict";

    var bought;

    var page = WinJS.UI.Pages.define("page.html", {

        ready: function (element, options) {

            document.getElementById("buyButton").addEventListener("click", showConfirmFlyout, false);

            document.getElementById("confirmButton").addEventListener("click", confirmOrder, false);

            document.getElementById("confirmFlyout").addEventListener("afterhide", onDismiss, false);

        }

    });

    function showConfirmFlyout() {

        bought = false;

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

        var buyButton = document.getElementById("buyButton");

        document.getElementById("confirmFlyout").winControl.show(buyButton);

    }

    function confirmOrder() {

        bought = true;

        WinJS.log && WinJS.log("You have completed your purchase.", "app", "status");

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

    }

    function onDismiss() {

        if (!bought) {

            WinJS.log && WinJS.log("The purchase was not completed.", "app", "status");

        }

    }

 

})();
