HTML Execution
Concepts
What’s HTML?
HTML is the main markup
language for creating web pages
and other information that can be
displayed in a web browser.
Each markup contains elements,
attributes or contents.
Each markup has different visual
effect or layout meanings.
Pure text, can be edited by text
editor.

<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset=“UTF-8”>
<style>
button
{
color: #FF0000;
}
</style>
<script>
function show() {
alert("Hello World");
}
</script>
</head>
<body>
<button onclick="show();">Click Me</button>
</body>
</html>
Execution of HTML
Browser downloads HTML
content from server pointed
by URL string.
Browser parse HTML, create
the object model at sandbox.
JavaScript code will be
initialized and fire on event
or sequence.
CSS guides the browser to
render the visual elements.

JavaScript Engine
HTML Context
A HTML sandbox and scope of
JavaScript execution.
Rendered DOM tree, can be
controlled by browser service.
Notification (event firing)
Represents all HTML elements
to object.
HTML API
HTML API is a set of interface can interact to HTML “object”.
HTML object represents a set of property and method for
public access.
Browser hosts objects and works with JavaScript.
HTML API
STATIC REFERENCE
Static Reference means the
JavaScript code is declared
statically.
DYNAMIC REFERENCE
Dynamic Reference means
JavaScript creates the object at
runtime.
HTML Context
function test(){
var httpRequest = new XMLHttpRequest();
httpRequest.send();
}
XMLHttpRequest
object{
// ...
function send(){
// ...
// send to server
// ...
}
// ...
}
Root node
Browser hosts each pages in window object, represents the
browser’s UI service.
Like: Open window, create a new dialog, control IFRAME,
change status bar or title, …

JavaScript History
Created by Netscape (Live Script) in 1994.
Renamed to JavaScript in 1995.
ECMA standard begins 1996, named ECMAScript.
Supported by all mainstream browsers.

Harmony
Abandoned
December 2009
Changes from prior edition
First edition
Editorial changes to keep the specification fully aligned with ISO/IEC 16262
international standard
Added regular expressions, better string handling, new control statements, try/catch
exception handling, tighter definition of errors, formatting for numeric output and
other enhancements
Fourth Edition was abandoned, due to political differences concerning language
complexity. Many features proposed for the Fourth Edition have been completely
dropped; some are proposed for ECMAScript Harmony.
Adds "strict mode", a subset intended to provide more thorough error checking and
avoid error-prone constructs. Clarifies many ambiguities in the 3rd edition
specification, and accommodates behaviour of real-world implementations that
differed consistently from that specification. Adds some new features, such as getters
and setters, library support for JSON, and more complete reflection on object
properties.[7]
This edition 5.1 of the ECMAScript Standard is fully aligned with third edition of the
international standard ISO/IEC 16262:2011
Version 6 is rumored to have support for classes, a concept long supported by
Work in progress. languages like Java, C++ and C#, in addition to multiple new concepts and language
features.

Regular Expression
Regular Expression provides a concise and flexible means to
"match" (specify and recognize) strings of text, such as
particular characters, words, or patterns of characters.
Common abbreviations for "regular expression" include regex
and regexp.
JavaScript supports Regular Expression by several methods.
test(): searches a string for a specified value, and returns true
or false, depending on the result
exec(): searches a string for a specified value, and returns the
text of the found value. If no match is found, it returns null.
JavaScript and HTML
JavaScript can interact to HTML DOM object model.

try {
writeMyFile(theData); //This may throw a error
}catch(e){
handleError(e); // If we got a error we handle it
}finally {
closeMyFile(); // always close the resource
}
Fire a new exception: throw statement

Used to draw graphics, on the fly, via scripting
(usually JavaScript)
HTML5 new tags (forms)
Tag
<datalist>
<keygen>
<output>
Description
Specifies a list of pre-defined options for input
controls
Defines a key-pair generator field (for forms)
Defines the result of a calculation
HTML5 Canvas
The HTML5 <canvas> element is used to draw graphics, on the
fly, via scripting (usually JavaScript).
The <canvas> element is only a container for graphics. You must
use a script to actually draw the graphics.
Canvas has several methods for drawing paths, boxes, circles,
characters, and adding images.
<canvas id="example" width="200" height="200">
This text is displayed if your browser does not support HTML5 Canvas.
</canvas>
var example = document.getElementById('example');
var context = example.getContext('2d');
context.fillStyle = 'red';
context.fillRect(30, 30, 50, 50);
HTML5 SVG
SVG stands for Scalable Vector Graphics, used to define vectorbased graphics for the Web.
SVG defines the graphics in XML format
SVG graphics do NOT lose any quality if they are zoomed or
resized
Every element and every attribute in SVG files can be animated
SVG is a W3C recommendation
<svg xmlns="http://www.w3.org/2000/svg" version="1.1"
height="190">
<polygon points="100,10 40,180 190,60 10,60 160,180"
style="fill:lime;stroke:purple;stroke-width:5;fillrule:evenodd;">
</svg>
Canvas vs. SVG
Canvas
• Resolution dependent
• No support for event handlers
• Poor text rendering capabilities
• You can save the resulting image
as .png or .jpg
• Well suited for graphic-intensive
games
SVG
• Resolution independent
• Support for event handlers
• Best suited for applications with
large rendering areas (Google
Maps)
• Slow rendering if complex
(anything that uses the DOM a
lot will be slow)
• Not suited for game applications

HTML5 defines a new element which specifies a standard way
to embed an audio file on a web page: the <audio> element.
<audio controls>
<source src="horse.ogg" type="audio/ogg">
<source src="horse.mp3" type="audio/mpeg">
Your browser does not support the audio element.

HTML5 APIs
The canvas element for immediate
mode 2D drawing. See Canvas 2D API
Specification 1.0 specification
Geolocation
Timed media playback
The Indexed Database API, an indexed
hierarchical key-value.
Offline Web Applications
Document editing
Drag-and-drop
Cross-document messaging
Browser history management
MIME type and protocol handler
registration
Microdata
Web Storage, a key-value pair storage
framework that provides behavior similar
to cookies but with larger storage capacity
and improved API.
Web SQL Database, a local SQL Database.
HTML5 File API, handles file uploads and
file manipulation.
Directories and System. This API is intended
to satisfy client-side-storage use cases not
well served by databases.
File Writer. An API for writing to files from
web applications.
Web Audio API, a high-level JavaScript API
for processing and synthesizing audio in
web applications.
Web Worker, Web sockets for client/server
communication.
Geolocation API
The HTML5 Geolocation API is used to get the geographical
position of a user. Since this can compromise user privacy, the
position is not available unless the user approves it.
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
}
else{
x.innerHTML="Geolocation is not supported by this browser.";
}
}
function showPosition(position) {
x.innerHTML="Latitude: " + position.coords.latitude +
"<br>Longitude: " + position.coords.longitude;
}
Geolocation API
function showError(error) {
switch(error.code) {
case error.PERMISSION_DENIED:
x.innerHTML="User denied the request for Geolocation."
break;
case error.POSITION_UNAVAILABLE:
x.innerHTML="Location information is unavailable."
break;
case error.TIMEOUT:
x.innerHTML="The request to get user location timed out."
break;
case error.UNKNOWN_ERROR:
x.innerHTML="An unknown error occurred."
break;
}
}
Local Storage API
HTML5 includes 2 types of storage APIs:
The localStorage object stores the data with no expiration date. The data
will not be deleted when the browser is closed, and will be available the
next day, week, or year.
The sessionStorage object is equal to the localStorage object, except that
it stores the data for only one session. The data is deleted when the user
closes the browser window.
// detect local storage service is available.
if(typeof(Storage)!=="undefined")
{
// Yes! localStorage and sessionStorage support!
// Some code.....
}
else
{
// Sorry! No web storage support..
}
Local Storage API
localStorage object:
if (localStorage.clickcount){
localStorage.clickcount = Number(localStorage.clickcount)+1;
}
else {
localStorage.clickcount = 1;
}
$("#result").innerHTML = "clicked " + localStorage.clickcount + " time(s).";
sessionStorage object:
if (sessionStorage.clickcount){
sessionStorage.clickcount = Number(localStorage.clickcount)+1;
}
else {
sessionStorage.clickcount = 1;
}
$("#result").innerHTML = "clicked " + sessionStorage.clickcount + " time(s).";
Web Worker
A web worker is a JavaScript that runs in the background,
independently of other scripts, without affecting the
performance of the page. You can continue to do whatever you
want: clicking, selecting things, etc., while the web worker runs
in the background.
Web Worker
Define a job script in external script file:
var i=0;
function timedCount()
{
i=i+1;
postMessage(i); // fire Client’s onmessage event
setTimeout("timedCount()",500);
}
timedCount();
Web Worker
Initialize a new Web Worker:
if(typeof(w)=="undefined")
{
w=new Worker("demo_workers.js");
}
Handling Message Callback:
w.onmessage=function(event){
document.getElementById("result").innerHTML=event.data;
};
Terminate (Stop):
w.terminate();
Web Worker (Page-side)
Web page <-> Web Worker’s communication:
<script>
function sayHI() {
worker.postMessage({'cmd': 'start', 'msg': 'Hi'});
}
function stop() {
worker.postMessage({'cmd': 'stop', 'msg': 'Bye'});
}
function unknownCmd() {
worker.postMessage({'cmd': 'foobard', 'msg': '???'});
}
var worker = new Worker('doWork2.js');
worker.addEventListener('message', function(e) {
document.getElementById('result').textContent = e.data;
}, false);
</script>
Web Worker (Worker-side)
Web page <-> Web Worker’s communication:
self.addEventListener('message', function(e) {
var data = e.data;
switch (data.cmd) {
case 'start':
self.postMessage('WORKER STARTED: ' + data.msg);
break;
case 'stop':
self.postMessage('WORKER STOPPED: ' + data.msg);
self.terminate();
break;
default:
self.postMessage('Unknown command: ' + data.msg);
};
}, false);

JavaScript and CSS
Control CSS via jQuery:
hasClass(“class”)
addClass(“class”)
removeClass(“class”)
.css(“style”) – return specified style’s value.
.css(“style”, “value”) – set specified style’s value.
DOM’s style control:
HTML element’s style property.
Example: document.getElementById(“div1”).style.display =
“none”;
CSS Apply value sequences
Style sheets may have three different origins:
Author. The author specifies style sheets for a source document
according to the conventions of the document language. For instance,
in HTML, style sheets may be included in the document or linked
externally.
User: The user may be able to specify style information for a
particular document. For example, the user may specify a file that
contains a style sheet or the user agent may provide an interface that
generates a user style sheet (or behaves as if it did).
User agent: Conforming user agents must apply a default style
sheet (or behave as if they did). A user agent's default style sheet
should present the elements of the document language in ways that
satisfy general presentation expectations for the document language
(e.g., for visual browsers, the EM element in HTML is presented using
an italic font).
CSS Apply value sequences
Sort according to importance (normal or important) and origin
(author, user, or user agent). In ascending order of precedence:
user agent declarations (Low priority)
user normal declarations
author normal declarations
author important declarations
user important declarations (High priority)
(Reference: http://www.w3.org/TR/CSS21/cascade.html#specificity)
CSS Pseudo Class
<a>’s pseudo class sequence:
a:link {color:#FF0000;}
a:visited {color:#00FF00;}
a:hover {color:#FF00FF;}
a:active {color:#0000FF;}
/*
/*
/*
/*
unvisited link */
visited link */
mouse over link */
selected link */
a:hover MUST come after a:link and a:visited in the CSS definition in
order to be effective!!
a:active MUST come after a:hover in the CSS definition in order to be
effective!!
