Windows Phone – A Quick Look

Microsoft and HTML 5

Internet Explorer on the desktop, Windows Phone

A preview of PhoneGap on Windows Phone

Windows Phone Microsoft confidential.

A quick look at Windows Phone

vs. People Icons

Internet beyond the browser. A fast, beautiful web experience

with Internet Explorer 9 and hardware acceleration.

Local Scout provides suggestions and prioritized local search results on restaurants, shopping and things to do.

Modern communication built in.

People Hub with Facebook, LinkedIn and Twitter, built in.

Group friends, pin them to Start for live updates and text, email and IM them all at once.

Facebook Chat, Messenger, check-ins, and photo tagging built in.

A smarter way to app. Pin apps to the Start screen for

live updates at a glance.

Apps connected to your searches make them easier to discover and use.

Windows Phone puts people at the center making it easier to connect and share with friends, family and colleagues, so you never miss a moment.

What Developers Told Us Interoperability and Same Markup

HTML5 Canvas, Audio, Video, XHTML, SVG, DOM L2 Core, DOM L2 & L3 Events, CSS3 Selectors, DOM Traversal, DOM Range, HTML5 Parsing, etc.

Performance Holistic Focus on Performance, Faster JavaScript, GPU Powered

Graphics

Websites more like native applications Reducing the User Interface surface area, Unlocking the

Hardware

Safe and Trusted Browsing No ActiveX Controls, no Browser Helper Objects, no Plug-ins or

Binary Behaviors

Understanding Today’s Sites

Key IE9 Mango Features

Key IE9 Windows Phone Technologies for Mobile

• Support for Viewport <meta> tag

• Support for W3C Geolocation, including GPS

• Full support for CSS Media Queries

• DOM Local Storage and Session Storage

• Data URIs

Controlling the Viewport

Controlling the Viewport

Viewport Property Description

width Sets the width of the viewport. Can be either an integer value or "device-width". Defaults to 1024 on Windows Phone, 980 on iPhone

height Sets the height of the viewport. Can be either an integer value or "device-height".

initial-scale Sets the initial scale value of the viewport. Defaults to 1.0.

maximum-scale Determines the maximum scale value of the viewport. Range is from 0.1 to 10.0

minimum-scale Determines the minimum scale value of the viewport. Range is from 0.1 to 10.0

user-scalable Boolean that determines whether the user can scale the viewport

Using Media Queries Provide a way of applying style sheets based upon certain

characteristics of the media Window size, screen size, aspect ratio, color depth,

resolution, etc. Are a W3C candidate recommendation as of July 2010 Specification can be found at

http://www.w3.org/TR/css3-mediaqueries/ <link rel="stylesheet" media="screen and (max-width:800)" href="example.css" />

@media screen and (max-width:800) { /* style definitions that apply to screens less than 800px wide */ }

Using Media Queries Media Query Feature

Description

width Indicates an output surface, such as a window, of exactly width units (px, etc.)

height Indicates an output surface, such as a window of exactly height units

device-width Indicates a device that has exactly the given width, in given units

device-height Indicates a device that has exactly the given height, in given units

orientation Used with “portrait” or “landscape” for devices that can do both.

Using Media Queries

http://mediaqueri.es/popular/

Geolocation Geolocation allows a phone to figure out where it is

IP Address location or Wireless network location

Triangulation of cellular towers

GPS device that uses satellite signals

Can get location as a "one-shot" or continuously

Location is always opt-in

“User Agents must not send location information to Web sites without the express permission of the user.”

W3C Geolocation API

http://www.w3.org/TR/geolocation-API/

Geolocation

API: getCurrentPosition(successFn, errFn, options) watchPosition(successFn, errFn, options) clearWatch(watchID) successFn( positionObject ) errFn( positionErrorObject )

Client-side LocalStorage / SessionStorage

Provides easier way of storing data on client without cookies

DOM Storage API Available from the window object: window.localStorage

window.sessionStorage

getItem(key) setItem(key, value) removeItem(key) clear() key(index) length

Things to remember about DOM Storage

Data is stored as strings – if you store other types, you must convert them yourself

Example:

setItem("mysite.product.price", 59.99);

var price = parseFloat("mysite.product.price");

If you try to store more than 5MB, an exception of type QUOTA_EXCEEDED_ERR is thrown

There is currently no way to request an increase in the available storage space in any of the browsers

The data:// URI Defines a way for embedding content such as images

directly inline into markup or CSS content

Used to reduce the number of HTTP requests

IE9 allows data URIs up to 4GB in size

General Format:

data:[mime-type][;base64],<image data as text>

Data URI Usage Use data URIs in place of normal URLs:

Replaces:

.rule { background-image:url(‘http://imagename.png’) }

.rule { background-image: url(‘data:image/png;base64,00af037491806ed...’) }

Replaces:
