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

});

})();


Output:
