The code in this topic is the sample file for Quickstart: Debug HTML and CSS. The errors present by design in the QuickStart are fixed in this version of the code.

Sample Code

The following HTML code is used in the <body> tag in the QuickStart.

<div id="flipTemplate" data-win-control="WinJS.Binding.Template"
         style="display:none">
    <div class="fixedItem" >
        <img src="#" data-win-bind="src: flipImg" />
    </div>
</div>
<div id="fView" data-win-control="WinJS.UI.FlipView" data-win-options="{
    itemDataSource: Data.items.dataSource, itemTemplate: flipTemplate }">
</div>

The following CSS shows the additions made to default.css.

#fView {
    background-color:#0094ff;
    height: 500px;
    margin: 25px;
}

The following code example shows the complete JavaScript code in default.js. The references to WinJS namespaces for this code are in the template's default.html file.

(function () {
    "use strict";

    var app = WinJS.Application;
    var activation = Windows.ApplicationModel.Activation;

    var myData = [];
    for (var x = 0; x < 3; x++) {
        myData[x] = { flipImg: "/images/logo.png" }
    };

    var pages = new WinJS.Binding.List(myData, { proxy: true });

    app.onactivated = function (args) {
        if (args.detail.kind === activation.ActivationKind.launch) {
            if (args.detail.previousExecutionState !==
            activation.ApplicationExecutionState.terminated) {
                // TODO: . . .
            } else {
                // TODO: . . .
            }
            args.setPromise(WinJS.UI.processAll());

            updateImages();
        }
    };

    function updateImages() {

        pages.setAt(0, { flipImg: "http://public-domain-photos.com/free-stock-photos-1/flowers/cactus-76.jpg" });
        pages.setAt(1, { flipImg: "http://public-domain-photos.com/free-stock-photos-1/flowers/cactus-77.jpg" });
        pages.setAt(2, { flipImg: "http://public-domain-photos.com/free-stock-photos-1/flowers/cactus-78.jpg" });
    };

    app.oncheckpoint = function (args) {
    };

    app.start();

    var publicMembers = {
        items: pages
    };

    WinJS.Namespace.define("Data", publicMembers);

})();
