Rating an Element With ListView in Windows Store Apps

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>

</head>

</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>

<head>

</head>

<body>

</div>

</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:
