Introduction
Today we are going to learn how to create Windows Store Apps for a rating in a list view using JavaScript. This example shows how to add rating controls to items in the List View.
In the previous article I described the page rating without using a list view, to see the article visit page rating in Windows Store Apps using JavaScript. In many apps we feel the need to rate several items. For this we use a list view to provide items in a list and allow the users to rate them easily. 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 two JavaScript pages by right-clicking on the js folder in the Solution Explorer and select Add > new item > JavaScript Page and then give an appropriate name. In the same way, add one HTML pages to your project.

Write the following code in default.aspx:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>App</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/script1.js"></script>
<script src="/js/default.js"></script>
</head>
<body role="application" style="background-color: chocolate">
<center><div style="width:500px"> <div id="rootGrid">
<div id="content">
<h1 id="featureLabel"></h1>
<div id="contentHost"></div>
</div>
</div>
</div></center>
</body>
</html>
Write the following code in default.js:
(function () {
"use strict";
var sampleTitle = "Rating Apps";
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 (evt) {
var url = evt.detail.location;
var host = document.getElementById("contentHost");
host.winControl && host.winControl.unload && host.winControl.unload();
WinJS.Utilities.empty(host);
WinJS.UI.Pages.render(url, host).then(function () {
WinJS.Application.sessionState.lastUrl = url;
});
});
WinJS.Namespace.define("App", {
sampleTitle: sampleTitle,
pages: pages
});
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Application.start();
})();
Write the following code in page.html:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script src="/js/script.js"></script>
<link rel="stylesheet" href="/css/listview.css" />
</head>
<body>
<div data-win-control="App.pageInput">
</div>
<div data-win-control="App.pageOutput">
<div id="MyItemTemplate" data-win-control="WinJS.Binding.Template" style="display: none">
<div class="regularListIconTextItem">
<img class="regularListIconTextItem-Image" data-win-bind="src: picture" />
<div class="regularListIconTextItem-Detail">
<h4 data-win-bind="innerText: title"></h4>
<div class="ratings win-interactive" data-win-control="WinJS.UI.Rating" data-win-bind="winControl.userRating: rating">
</div>
</div>
</div>
</div>
<div data-win-control="WinJS.UI.ListView" data-win-options="{ itemDataSource: myData.dataSource, itemTemplate: MyItemTemplate, selectionMode: 'none', tapBehavior: 'none', swipeBehavior: 'none', layout: { type: WinJS.UI.ListLayout } }">
</div>
</div>
</body>
</html>
Write the following code in script.js:
var myData = new WinJS.Binding.List([
{ title: "", picture: "images/1.jpg", rating: 5 },
{ title: "", picture: "images/2.jpg", rating: 4 },
{ title: "", picture: "images/3.jpg", rating: 5 },
{ title: "", picture: "images/4.jpg", rating: 5 }
]);
(function () {
"use strict";
var page = WinJS.UI.Pages.define("page.html", {
ready: function (element, options) {
if (document.styleSheets[0].disabled === true) {
document.getElementById("darkStyle").checked = true;
document.getElementById("lightStyle").checked = false;
}
}
});
})();
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]);
}
}
);
WinJS.log = function (message, tag, type) {
var statusDiv = document.getElementById("statusMessage");
};
function activated(e) {
WinJS.Utilities.query("#featureLabel")[0].textContent = App.sampleTitle;
}
WinJS.Application.addEventListener("activated", activated, false);
WinJS.Namespace.define("App", {
pageOutput: pageOutput
});
})();
Output:
