JQuery is a fast and
concise JavaScript Library created by John Resig in 2006 with a nice motto: Write
less, do more.
jQuery simplifies HTML document
traversing, event handling, animating, and Ajax
interactions for rapid web development.
jQuery is a JavaScript toolkit designed
to simplify various tasks by writing less code. Here is the list of important
core features supported by jQuery:
- DOM manipulation: The jQuery
made it easy to select DOM elements, traverse them and modifying their
content by using cross-browser open source selector
engine called Sizzle.
- Event handling: The jQuery
offers an elegant way to capture a wide variety of events, such as a user
clicking on a link, without the need to clutter the HTML code itself with
event handlers.
- AJAX Support: The jQuery
helps you a lot to develop a responsive and feature-rich site using AJAX technology.
- Animations: The jQuery
comes with plenty of built-in animation effects which
you can use in your websites.
- Lightweight: The jQuery
is very lightweight library - about 19KB in size ( Minified and gzipped ).
- Cross Browser Support: The jQuery
has cross-browser support, and works well in IE 6.0+, FF 2.0+, Safari
3.0+, Chrome and Opera 9.0+
- Latest Technology: The jQuery
supports CSS3 selectors and basic XPath syntax.
This is very simple to do require setup
to use jQuery library. You have to carry two simple steps:
2. Now put
downloaded jquery-1.3.2.min.js file in a directory of your
website, e.g. /jquery.
The downloaded file name
jquery-1.3.2.min.js may vary for your version. Your minified version would be
kind of unreadable which would not have any new line or unnecessary words in
it.
The jQuery does not require any special
installation and very similar to JavaScript, we do not need any compilation or
build phase to use jQuery.
