2. A JavaScript library that simplifies client-
side scripts of HTML
A lightweight, "write less, do more",
JavaScript library. – w3schools
Open Source JavaScript Library
3. Written in JavaScript, and comes in the
form of a single .js file, compiled within
are a lot of JavaScript codes that are
commonly used by programmers
Takes common tasks that use many lines
of JavaScript code, and wraps them into
methods that can be called by a line of
code.
4. Of all scripts, jQuery is also used by
companies like:
Google
Microsoft
IBM
Netflix
5. Comes in two forms:
› Uncompressed .js file – easy to read and
modify. (160kb)
› Minified .js file – comments and other
unnecessary characters are removed to a
smaller size(23kb). More commonly used
since it is smaller and is accessed much
easier than the uncompressed form.
6. As it contains advanced page
manipulation functions, it is simple to
understand
It can create very impressive animations
and interactions
Accomplish more with less codes
JQuery aims to ease common problems by
providing a lightweight library that adds
many advanced and cross-browser
functions to the standard language.
7. Using direct JavaScript can cause issues
related to browser incompatibilities. Those
issues have made many JavaScript
applications difficult to code, resulting in
high maintenance costs.
A modern Web application wouldn't be
complete without some AJAX functionality.
JQuery provides functions for sending HTTP
GET and POST requests, and it can work
easily with the JavaScript Object Notation
(JSON) format.
8. jQuery makes it easy to write JavaScript
apps and create animated effects that rival
that of Flash movies.
jQuery is also credited for:
› Adding animated effects to elements.
› Making XML (Ajax) requests. These use
JavaScript to request additional data from the
Web server without having to reload the page.
› Manipulating the DOM (Document Object
Model). Easily add, remove, and reorder content
in the Web page using just a few lines of code.
9. › Creating image slideshows.
› Making drop-down menus. WITH
ANIMATIONS!
› Creating drag-and-drop interfaces.
› Adding power to forms. With jQuery you can
easily add complex client-side form
validation, create auto-complete Ajax text
fields that pull data from a server-side
database, and so on.
10. A text-based open standard designed
for human-readable data interchange. It
is derived from the JavaScript scripting
language for representing simple data
structures and associative arrays, called
objects. Despite its relationship to
JavaScript, it is language-independent,
with parsers available for many
languages.
