The document discusses HTML5 and its new features such as video, canvas, geolocation, drag and drop, full screen, camera, battery status, vibration, and WebGL. It provides code examples for implementing these features and encourages trying new things with HTML5. The document is presented by Robert Nyman who works at Mozilla and advocates for open web standards and HTML5.

1. HTML5 &
The Open Web

2. Mozilla is a
global non-
profit dedicated
to putting you
in control of
your online
experience and
shaping the
future of the
Web for the
public good

5. What is HTML5?

6. Semantics APIs

7. Platforms!

9. must die!!!
rea lly
Not

10. HTML5 semantics

12. <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

13. <meta charset="utf-8">

14. <header> <aside>
<article> <nav>
<section> <figure>
<footer> <figcaption>

15. Video

20. <video controls src="nasa.webm"></video>

22. Canvas

25. pdf.js

26. <canvas id="my-canvas" width="500" height="500">
I am canvas
</canvas>

27. var canvas = document.getElementById("my-canvas"),
context = canvas.getContext("2d");
context.fillStyle = "#f00";
context.fillRect(0, 0, 100, 100);
context.clearRect(40, 40, 20, 20);

28. Geolocation

32. if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
alert(position.coords.latitude + ", " + position.coords.longitude);
});
}

33. Drag and Drop

34. Fullscreen

37. <button id="view-fullscreen">Fullscreen</button>
<script type="text/javascript">
(function () {
var viewFullScreen = document.getElementById("view-fullscreen");
if (viewFullScreen) {
viewFullScreen.addEventListener("click", function () {
var docElm = document.documentElement;
if (docElm.mozRequestFullScreen) {
docElm.mozRequestFullScreen();
}
else if (docElm.webkitRequestFullScreen) {
docElm.webkitRequestFullScreen();
}
}, false);
}
})();
</script>

38. mozRequestFullScreenWithKeys?

39. html:-moz-full-screen {
background: red;
}
html:-webkit-full-screen {
background: red;
}

40. Camera

42. <input type="file" id="take-picture" accept="image/*">

43. takePicture.onchange = function (event) {
// Get a reference to the taken picture or chosen file
var files = event.target.files,
file;
if (files && files.length > 0) {
file = files[0];
// Get window.URL object
var URL = window.URL || window.webkitURL;
// Create ObjectURL
var imgURL = URL.createObjectURL(file);
// Set img src to ObjectURL
showPicture.src = imgURL;
// Revoke ObjectURL
URL.revokeObjectURL(imgURL);
}
};

44. Boot to Gecko

47. https://github.com/andreasgal/B2G

48. Telephony & SMS

49. // Telephony object
var tel = navigator.mozTelephony;
// Check if the phone is muted (read/write property)
console.log(tel.muted);
// Check if the speaker is enabled (read/write property)
console.log(tel.speakerEnabled);
// Place a call
var call = tel.dial("123456789");

50. // Receiving a call
tel.onincoming = function (event) {
var incomingCall = event.call;
// Get the number of the incoming call
console.log(incomingCall.number);
// Answer the call
incomingCall.answer();
};
// Disconnect a call
call.hangUp();

51. // SMS object
var sms = navigator.mozSMS;
// Send a message
sms.send("123456789", "Hello world!");
// Recieve a message
sms.onrecieved = function (event) {
// Read message
console.log(event.message);
};

52. Battery

54. // Get battery level in percentage
var batteryLevel = battery.level * 100 + "%";
// Get whether device is charging or not
var chargingStatus = battery.charging;
// Time until the device is fully charged
var batteryCharged = battery.chargingTime;
// Time until the device is discharged
var batteryDischarged = battery.dischargingTime;

55. battery.addEventLister("levelchange", function () {
// Device's battery level changed
}, false);
battery.addEventListener("chargingchange", function () {
// Device got plugged in to power, or unplugged
}, false);
battery.addEventListener("chargingtimechange", function () {
// Device's charging time changed
}, false);
battery.addEventListener("dischargingtimechange", function () {
// Device's discharging time changed
}, false);

56. Vibration

57. (function () {
document.querySelector("#vibrate-one-second").addEventListener("click",
function () {
navigator.mozVibrate(1000);
}, false);
document.querySelector("#vibrate-twice").addEventListener("click",
function () {
navigator.mozVibrate([200, 100, 200, 100]);
}, false);
document.querySelector("#vibrate-long-time").addEventListener("click",
function () {
navigator.mozVibrate(5000);
}, false);
document.querySelector("#vibrate-off").addEventListener("click",
function () {
navigator.mozVibrate(0);
}, false);
})();

58. WebGL

63. squareVertexPositionBuffer = gl.createBuffer();
gl.bindBuffer(gl.ARRAY_BUFFER, squareVertexPositionBuffer);
vertices = [
1.0, 1.0, 0.0,
-1.0, 1.0, 0.0,
1.0, -1.0, 0.0,
-1.0, -1.0, 0.0
];
gl.bufferData(gl.ARRAY_BUFFER, new Float32Array(vertices), gl.STATIC_DRAW);
squareVertexPositionBuffer.itemSize = 3;
squareVertexPositionBuffer.numItems = 4;
}

64. var teapotPositions = new Float32Array([ 17.83489990234375, 0, 30.573999404907227,
