Introduction
In this article I describe how to use FlipView controls in Windows Store Apps using JavaScript. You can use a FlipView control to provide an option to see various images. I assume that you can develop a simple Windows Store App using JavaScript; for help with that visit Simple Windows Store Apps using JavaScript.
To start the creation of the app, add two JavaScript files by right-clicking on the js folder in Solution Explorer and give an appropriate name; here I give the names imgdata.js and script1.js respectively. The imgdata.js file contains the references of the images. Now add one HTML page by right-clicking on the name of your project in the Solution Explorer and give an appropriate name; I use page.html.
Now put the images in the image folder and right-click on the image folder then select add > existing item then select the image folder and select images and then ok.

Write the following code in default.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Example of flipview using JavaScript</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="/sample-utils/sample-utils.css" />
<link rel="stylesheet" href="/css/default.css" />
<script src="script1.js"></script>
<script src="/js/default.js"></script>
</head>
<body role="application" style="background-color: chocolate">
<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 default.js:
(function () {
"use strict";
var sampleTitle = "";
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("Apps", {
sampleTitle: sampleTitle,
pages: pages
});
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Application.start();
})();
Write the following code in page.html:
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="/js/imgdata.js"></script>
<script src="/js/simpleflipview.js"></script>
</head>
<body>
<div id="simple_ItemTemplate" data-win-control="WinJS.Binding.Template" style="display: none">
<div class="overlaidItemTemplate">
<img class="image" data-win-bind="src: picture; alt: title" />
<div class="overlay">
<h2 class="ItemTitle" data-win-bind="innerText: title"></h2>
</div>
</div>
</div>
<div id="simple_FlipView" class="flipView"
data-win-control="WinJS.UI.FlipView"
data-win-options="{ itemDataSource: imgdata.bindingList.dataSource, itemTemplate: simple_ItemTemplate }" style="width:350px " >
</div>
</div>
</body>
</html>
Write the following code in script1.js:
(function () {
var pageOutput = WinJS.Class.define(
function (element, options) {
element.winControl = this;
this.element = element;
new WinJS.Utilities.QueryCollection(element)
.setAttribute("role", "region")
.setAttribute("aria-labelledby", "outputLabel")
.setAttribute("aria-live", "assertive");
element.id = "output";
this._addOutputLabel(element);
this._addStatusOutput(element);
}, {
_addOutputLabel: function (element) {
var label = document.createElement("h2");
label.id = "outputLabel";
label.textContent = "Output";
element.parentNode.insertBefore(label, element);
},
_addStatusOutput: function (element) {
var statusDiv = document.createElement("div");
statusDiv.id = "statusMessage";
element.insertBefore(statusDiv, element.childNodes[0]);
}
}
);
var currentpageUrl = null;
WinJS.Navigation.addEventListener("navigating", function (evt) {
currentpageUrl = evt.detail.location;
});
WinJS.log = function (message, tag, type) {
var statusDiv = document.getElementById("statusMessage");
};
function activated(e) {
WinJS.Utilities.query("#featureLabel")[0].textContent = Apps.sampleTitle;
}
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Namespace.define("Apps", {
pageOutput: pageOutput
});
})();
Write the following code in imgdata.js:
(function () {
"use strict";
var array = [
{ type: "item", title: "1rst img", picture: "images/1.jpg" },
{ type: "item", title: "2nd img", picture: "images/2.jpg" },
{ type: "item", title: "3rd img", picture: "images/3.jpg" },
{ type: "item", title: "4th img", picture: "images/4.jpg" },
{ type: "item", title: "5th img", picture: "images/5.jpg" },
{ type: "item", title: "6th img", picture: "images/6.jpg" }
];
var bindingList = new WinJS.Binding.List(array);
WinJS.Namespace.define("imgdata", {
bindingList: bindingList,
array: array
});
var e = imgdata.bindingList.dataSource;
})();
