Action Confirmation Windows Store Apps

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>

</head>

</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>

</head>

<body>

<p>

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

</p>

Buy</button>

<br />

</div>

</div>

<div>

Your account will be charged 1000rs.

</div>

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");

}

})();

Output
