JavaScript is a scripting language that allows adding interactivity to HTML pages. It can react to events, read and write HTML elements, validate data, detect the visitor's browser, create cookies, and more. The DOM defines a standard for accessing and manipulating HTML documents. JavaScript uses objects, functions, and prototypes for object-oriented programming. Key concepts include encapsulation, inheritance, and abstraction. Events follow the capturing and bubbling phases. JavaScript supports conditionals, loops, functions, scopes, closures, and more.

Web components allow developers to create reusable custom elements using existing web standards like HTML templates and shadow DOM. They consist of four main technologies - HTML templates for reusable markup, HTML imports to include dependencies, custom elements to define new types of elements with custom behavior, and shadow DOM for encapsulating styles and markup. Major browsers have implemented support for these standards to different extents, and libraries exist to simplify web component development. Companies are adopting web components for applications that benefit from encapsulated reusable UI components.

Core Data with multiple managed object contextsMatthew Morey
When using Core Data for persisting app data multiple managed object contexts (MOC) are often required to avoid blocking UI. Typically you would create a background MOC and listen for changes on the main MOC, merging changes as necessary. With iOS 5, MOCs now have parent context and the ability to set concurrency types. These new features greatly simplify dealing with Core Data on background queues. During this presentation Matt will cover the pros and cons of this new method of dealing with Core Data.
Debugging in JavaScript
It is common to have errors while writing codes and the errors can be due to syntax or logical. These errors create a lot of ambiguity in the logic and understanding of both users and programmers. There can also be errors in the code which can remain invisible to the programmer’s eye and can create havoc. To identify these errors we need Debuggers that can go through the entire code or program, identify the errors and also fix them.
-Debugger
The debugger keyword is used in the code to force stop the execution of the code at a breaking point and calls the debugging function. The debugger function is executed if any debugging is needed at all else no action is performed.
jQuery provides a trivially simple interface for doing various kind of amazing effects. jQuery methods allow us to quickly apply commonly used effects with a minimum configuration. This tutorial covers all the important jQuery methods to create visual effects.

JavaScript can dynamically manipulate the content, structure, and styling of an HTML document through the Document Object Model (DOM). The DOM represents an HTML document as nodes that can be accessed and modified with JavaScript. Common tasks include dynamically creating and adding elements, handling user events like clicks, and updating content by accessing DOM elements by their id or other attributes.
Javascript allows interactive content on web pages and control of the browser and document. It is an interpreted scripting language that is cross-platform but support varies. Javascript can provide interactive content, control document appearance and content, and interact with the user through event handlers.
HSC INFORMATION TECHNOLOGY CHAPTER 3 ADVANCED JAVASCRIPTAAFREEN SHAIKH
This document provides information about JavaScript including:
- JavaScript is a client-side scripting language used to make web pages dynamic. It was created by Brendan Eich at Netscape.
- There are two types of scripting languages - client-side (JavaScript, VBScript) and server-side (ASP, PHP, Perl). Client-side scripts run on the browser while server-side scripts run on the web server.
- JavaScript has various data types including strings, numbers, Booleans, undefined and null. It also has operators like arithmetic, comparison, logical and assignment operators.
- Functions, objects, and events are important concepts in JavaScript. Functions allow code to be reused, objects bundle data

This document provides an overview of how to script the DOM using JavaScript. It discusses how the browser parses HTML into a DOM tree, with the window and document objects being the root nodes. It then explains how to access and manipulate DOM elements using the body, JavaScript functions, and events. Finally, it covers creating custom objects and namespacing in JavaScript.
jQuery is a JavaScript framework that provides useful functionality for common programming tasks related to the client-side manipulation of web pages. It simplifies tasks like DOM manipulation, event handling, animation, and Ajax interactions. While powerful, jQuery is not a substitute for JavaScript and does not solve every problem - it works best when used to enhance JavaScript where it makes tasks easier. jQuery selects elements, applies functions to matched elements, and returns jQuery objects to allow chaining of methods.
This document provides an overview of event handling in web development using JavaScript. It discusses what functions and event handlers are, and how they can be defined and used to handle user interactions on a webpage. Specifically, it explains how event handlers allow capturing events like mouse clicks or focus changes and executing JavaScript code in response. It provides examples of common event handlers like onClick, onMouseOver, onLoad, and onUnload, and how they can be used both inline in HTML tags or by calling JavaScript functions. The goal is to help readers understand how to use event handlers to make their webpages interactive.
This document provides an introduction and overview of jQuery. It discusses how jQuery simplifies DOM navigation and manipulation, handles browser differences, and makes JavaScript coding easier. The document covers basic jQuery concepts like selectors, the jQuery function, attributes, and events. It also provides examples of common jQuery code.

It discusses how JavaScript can be used to add interactivity to web pages by manipulating the HTML document object model directly in the browser. It covers the basics of the JavaScript language including variables, data types, operators, and control structures. It also introduces common JavaScript objects like Date, String, Array, and Math that are used to work with dates, strings, arrays of values and mathematical functions respectively. The document provides examples of how to define and call functions in JavaScript.
jQuery is a JavaScript library that simplifies HTML document traversal, event handling, animating, and Ajax interactions. It was created in 2006 with the goal of writing less code to do more. jQuery simplifies tasks like selecting elements, handling events, performing animations and AJAX calls to make web development faster.
This article is the first part of a series of articles on using JavaScript tools. Today, JavaScript is a very powerful language that can be used to build web apps, mobile apps, and even some pc games — perhaps a bit faster than you would build them otherwise.
New libraries have emerged in the web industry to address the challenges of JavaScript — libraries such as JQuery, Prototype and many others have been released. Today, a popular question asked by many is — should i learn the libraries such as jQuery or learn basic JavaScript. The truth is that the libraries help you to create faster, responsive JavaScript, but there are still times when your basic knowlege of JavaScript will be called into question. It is for this reason that I have created this eBook, to assist newbies learn JavaScript.

javascript Event Handling and introduction to event.pptLalith86
This document provides an overview of event handling in JavaScript. It discusses how event handlers allow programs to capture and respond to events, making them event-driven. It describes two methods for handling events - inline JavaScript and defining functions in the head. Common event handlers like onClick, onMouseOver, onFocus, onBlur, onLoad and onUnload are presented along with examples. The document aims to help readers understand the concept and benefits of event handlers and write simple programs using them.
JavaScript was originally named Mocha but was renamed LiveScript and then JavaScript. It is a lightweight, interpreted programming language designed for creating network-centric and browser-based applications. JavaScript can be used for client-side scripting through features like popup boxes and event handling, and for server-side scripting by running JavaScript code on the server with Node.js. It includes basic datatypes, operators, control flows, and built-in objects for manipulating the browser and its DOM.
This was a presentation I wrote for a previous employer, aimed at Java developers. The goal was to help them understand some of the new UI conventions I was putting into their application, so that they would be able to develop "smarter" JSP code.
2. Introduction to JavaScript
JavaScript is the most popular and incredibly powerful
scripting language.
JavaScript was designed to add interactivity to HTML pages
JavaScript is a scripting language
A scripting language is a lightweight programming language
JavaScript is usually embedded directly into HTML pages
JavaScript is an interpreted language (means that scripts execute without
preliminary compilation)
Everyone can use JavaScript without purchasing a license
3. What can JavaScript do?
JavaScript gives HTML designers a programming tool
JavaScript can react to events
A JavaScript can be set to execute when something happens, like when a page has finished
loading or when a user clicks on an HTML element
JavaScript can read and write HTML elements
A JavaScript can read and change the content of an HTML element
JavaScript can be used to validate data
A JavaScript can be used to validate form data before it is submitted to a server. This saves the
server from extra processing
4. What can JavaScript do?
JavaScript can be used to detect the visitor's browser
A JavaScript can be used to detect the visitor's browser, and - depending on the browser - load
another page specifically designed for that browser
JavaScript can be used to create cookies
A JavaScript can be used to store and retrieve information on the visitor's computer
5. JavaScript Syntax
The HTML <script> tag is used to insert a JavaScript into an HTML page.
The <script> and </script> tells where the JavaScript starts and ends.
You can place an unlimited number of scripts in your document, and you can
have scripts in both the body and the head section at the same time.
A simple example of JavaScript:
//Example 1.
<script type="text/javascript">
... some JavaScript code ...
</script>
6. Document Object Model
"The W3C Document Object Model (DOM) is a platform and language-neutral
interface that allows programs and scripts to dynamically access and update
the content, structure, and style of a document.”
The HTML DOM defines a standard for accessing and manipulating HTML
documents.
The DOM is a W3C (World Wide Web Consortium) standard.
The Dom is Platform- and language-independent.
7. HTML DOM
DOM Nodes - In the DOM, everything in an HTML document is a node.
The DOM says:
1. The entire document is a document node
2. Every HTML element is an element node
3. The text in the HTML elements are text nodes
4. Every HTML attribute is an attribute node
5. Comments are comment nodes
The HTML DOM views an HTML document as a node-tree.
All the nodes in the tree have relationships to each other.
8. Node Parent, Children & Sibling
The nodes in the node tree have a hierarchical relationship to each other.
The terms parent, child, and sibling are used to describe the relationships.
Parent nodes have children. Children on the same level are called siblings
(brothers or sisters).
In a node tree, the top node is called the root
Every node has exactly one parent node, except the root which has no
parent
A node can have any number of children
A leaf is a node with no children
Siblings are nodes with the same parent
9. Selector
jQuery selectors allow you to select and manipulate HTML element(s).
It's based on the existing CSS Selectors
All selectors in jQuery start with the dollar sign and parentheses: $()
Example :
$("p") // Tag Selector
$("#test") // ID selector
$(".test") // Class selector
10. DataTypes
Call by Value
String
Number
Boolean,Null, Undefined.
Call by reference
Array // [ ‘a’ , ‘b’ , ‘c’ ]
Object // { 0 : ’a’ , 1 : ’b’, 2 : ’c’}
JavaScript has dynamic types. This means that the same variable can be used as
different types:
var x; // Now x is undefined
var x = 5; // Now x is a Number
var x = "John"; // Now x is a String
11. Conditionals, Loops & Operators
Conditions Loops Operators
if statement for Arithmetic Operators (+ ,- ,* ,/ ,% ,++ ,--)
if...else statement while Comparison Operators (== ,!=. ,> ,< ,>= ,<=)
if...else if....else statement do while Logical (or Relational) Operators (&&, ||, !)
switch statement for in
Assignment Operators (= ,+= ,-= ,*= ,/= ,%=)
Conditional (or ternary) Operators (? :)
12. Typeof & instanceof using jQuery
typeof
It’s is a unary operator that is placed before its single operand, which can be of any type. Its
value is a string indicating the datatype of the operand.
Example:
typeof 2 // “number”
typeof {} // “object”
instanceof
The instanceof operator tests whether an object has in its prototype chain the prototype property
of a constructor.
Example:
[] instanceof Array //true
[] instanceof Object //true
13. Function
Function Syntax in JS:
function functionName(parameters) {
code to be executed
}
A function can be invoked:
When an event occurs (when a user clicks a button)
When it is invoked (called) from JavaScript code
Automatically (self invoked)
14. Scope
There are only two scopes in JS:
Local
A variable declared (using var) within a JavaScript function becomes LOCAL to the function.
The variable gets a local scope: It can only be accessed from within that function.
Local variables can have the same name in different functions, because they are only
recognized by the function where they were declared.
Arguments (parameters) work as local variables inside functions.
Local variables are created when the function starts, and deleted when the function is
completed.
Global
A variable declared outside a function, becomes GLOBAL.
The variable gets a global scope: All scripts and functions on the web page can access it.
15. Closures
Closures are functions that refer to independent (free) variables.
In other words, the function defined in the closure 'remembers' the environment in which it was
created.
function makeFunc() {
var name = "Mozilla";
function displayName() {
alert(name);
}
return displayName;
}
var myFunc = makeFunc();
myFunc();
Change page font size using JS closures
16. Events
In its most ancient form an event handler looks like this.
<a href="somewhere.html" onclick="alert('I've been clicked!')"> (de facto standardized by Netscape)
element.onclick = doSomething;
function doSomething(e) {
if (!e) var e = window.event
// e refers to the event
// this refers to the HTML element which currently handles the event
// target/srcElement refer to the HTML element the event originally took place on
}

18. Element 1
Event order Bubbling and Capturing
“If an element and one of its ancestors have an event handler for the same
event, which one should fire first?”
Netscape Model Microsoft Model W3C Model
Netscape said that the event on
element1 takes place first. This is
called event capturing.
Microsoft maintained that the event
on element2 takes precedence.
This is called event bubbling.
In the W3C event model is first
captured until it reaches the target
element and then bubbles up again.
Element 2
Element 1
Element 2
Element 1
Element 2
19. Advanced event registration model
It offers a simple way to register as many event handlers as you like for the
same event on one element.
W3C (IE9+ and others)
element.addEventListener('click',doSomething,false)
element.removeEventListener('click',spyOnUser,false)
last argument of addEventListener, it is meant to state whether the event handler should
be executed in the capturing or in the bubbling phase.
Microsoft (IE5+)
element.attachEvent('onclick',startDragDrop)
element.detachEvent('onclick',spyOnUser)
20. Benefits of add/bind Event to an element
over direct event binding
Can easily add and remove an event listener by using the addEventListener() and
removeEventListener() method respectively.
Attaches an event handler to an element without overwriting existing event handlers.
Can add many event handlers to one element.
can add many event handlers of the same type to one element, i.e two "click" events.
Can add event listeners on any HTML DOM object such as HTML elements, the HTML
document, the window object, or other objects that supports events, like the
xmlHttpRequest object.
21. Constructor and Custom Objects
JavaScript is a prototype-based language which contains no class statement.
Constructor
function Person(gender) {
this.gender = gender;
alert('Person instantiated');
}
Custom Objects
var person1 = new Person('Male');
var person2 = new Person('Female');
24. Encapsulation
Encapsulation is the packing of data and functions into a
single component. ~ Wiki
A method of bundling the data and methods that use the
data. ~ MDN
25. Exp.
function Class_ABC() {
var msg = “Hello Mr.” ; // private
data
var Reply = function (){ // private
method
alert(‘Yes, How may i help you.’)
}
this.x = 2; //
public data
this.sum = function () { //
public member
alert('Add x with 10: ' + (this.x + 10))
}
}
var instance = new Class_ABC()
instance.sum(); // output Add x with 10: 12
instance.x // output 2
instance msg // output undefined
function xyz() {
var x = 10; // private
var y = 20; // private
return {
add : function(){ // public
alert(x +y)
},
sub : function(){ // public
alert(y-x)
}
} //end of return
}// end of function
var p = xyz();
p.add() // output 30
p.sub() // output 10
26. Abstraction
● Abstracting only the aspects/information which are
relevant for a particular purpose/user.
OR
● Suppressing the more complex details below the
current level.
27. Inheritance
A class can inherit characteristics from another class.
Different ways to achieve inheritance
● Prototype-based
● By using call/Apply Function
28. function Person(gender) {
this.gender = gender;
}
Person.prototype.sayGender = function () {
alert(this.gender);
};
var person1 = new Person('Male');
person1.sayGender(); // alerts 'Male'
Inheritance (Prototype-based)
29. function baseClass() {
this.x = 2;
this.y = 4;
this.sum = function () {
alert('Hi, i am defined inside base
class: ' + (this.x + this.y));
}
}
Inheritance(By using call Function)
function subClass() {
baseClass.call(this); // to inherit base class members
alert(this.x)
alert(this.y)
}
var inst = new subClass();
inst.sum();
30. Type of Inheritance
Single Inheritance
Multilevel Inheritance
Hierarchical Inheritance
Hybrid Inheritance
Multiple Inheritance
31. Polymorphism
… Poly means "many" and morphism means "forms".
Types:
● function overloading
● function overriding
Different classes might define the same method or property.
32. function baseClass() {
this.x = 2;
this.y = 4;
this.sum = function () {
alert('Hi, i am defined inside base
class: ' + (this.x + this.y))
}
}
Polymorphism
function subClass() {
baseClass.call(this); // to inherit base class members
this.sum = function () {
alert('Hi, i am defined inside subClass and baseClass
sum function is overridden by me: ' + (this.x + this.y + 10))
}
}
x = new baseClass();
x.sum();
y = new subClass();
y.sum();
33. Qunit : JavaScript unit testing framework
QUnit.test( "hello test", function( assert ) {
assert.equal( 1 == "1", "Passed!" );
});
● We maintain separate copy
of our testable code and
production ready code.
● It lets you test private
functions without exposing
them on live.

35. Optimization
Level of the scope chain must be minimum.
Use module/feature specific checks in case of cross browser issues.
Array’s length should not be recomputed in loops.
Include scripts at end of the page or use dynamic inclusions.
Minify and gzip the resources.
