Introduction

Today we are going to learn how to create a Windows Store App tor pick a Contact using JavaScript. This app demonstrates how to use the Contact Picker to select one contact. It includes a basic implementation of the Contact Picker APIs to demonstrate how to display a list of contacts to the user.

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 app, 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 page to your project.

Write the following code in default.html:

<!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/script.js"></script>

    <script src="/js/default.js"></script>

</head>

<body role="application"style="background-color:gray">

    <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 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("Apps", {

        appTitle: appTitle,

        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/pageSingle.css" />

</head>

<body>

    <div data-win-control="Apps.pageInput">

       <button id="open">Pick contact</button>

        <br /><br />

    </div>

    <div data-win-control="Apps.pageOutput">

    </div>

</body>

</html> 


Write the following code in script.html:
 

(function () {

    "use strict";

    var page = WinJS.UI.Pages.define("page.html", {

        ready: function (element, options) {

            document.getElementById("open").addEventListener("click", pickContact, false);

        }

    });

 

    function pickContact() {

        WinJS.log && WinJS.log("", "app", "status");

        var viewState = Windows.UI.ViewManagement.ApplicationView.value;

        if (viewState === Windows.UI.ViewManagement.ApplicationViewState.snapped &&

            !Windows.UI.ViewManagement.ApplicationView.tryUnsnap()) {

            return;

        };

        var picker = new Windows.ApplicationModel.Contacts.ContactPicker();

        picker.commitButtonText = "Select";

        picker.pickSingleContactAsync().done(function (contact) {

            if (contact !== null) {

                var contactElement = document.createElement("div");

                contactElement.className = "contact";

                contactElement.appendChild(createTextElement("h3", contact.name));

                appendFields("Emails:", contact.emails, contactElement);

                appendFields("Phone Numbers:", contact.phoneNumbers, contactElement);

                appendFields("Addresses:", contact.locations, contactElement);

                document.getElementById("output").appendChild(contactElement);

            } else {

                WinJS.log && WinJS.log("No contact was selected", "app", "status");

            }

        });

    }

 

    function appendFields(title, fields, container) {

        fields.forEach(function (field) {

            if (field.value) {              

                if (title) {

                    container.appendChild(createTextElement("h4", title));

                    title = "";

                }

                switch (field.category) {

                    case Windows.ApplicationModel.Contacts.ContactFieldCategory.home:

                        container.appendChild(createTextElement("div", field.value + " (home)"));

                        break;

                    case Windows.ApplicationModel.Contacts.ContactFieldCategory.work:

                        container.appendChild(createTextElement("div", field.value + " (work)"));

                        break;

                    case Windows.ApplicationModel.Contacts.ContactFieldCategory.mobile:

                        container.appendChild(createTextElement("div", field.value + " (mobile)"));

                        break;

                    case Windows.ApplicationModel.Contacts.ContactFieldCategory.other:

                        container.appendChild(createTextElement("div", field.value + " (other)"));

                        break;

                    case Windows.ApplicationModel.Contacts.ContactFieldCategory.none:

                    default:

                        container.appendChild(createTextElement("div", field.value));

                        break;

                }

            }

        });

    }

    function createTextElement(tag, text) {

        var element = document.createElement(tag);

        element.className = "singleLineText";

        element.innerText = text;

        return element;

    }

 

})(); 


Write the following code in script1.html:
 

(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.appTitle;

    }

 

    WinJS.Application.addEventListener("activated", activated, false);

    WinJS.Namespace.define("Apps", {

        pageOutput: pageOutput

    });

})();
