jQuery is a very lightweight Javascript library (some call it a framework), that takes most of the headache out from writing pure Javascript in your applications. It has many
very powerful features, some of which include: easily traversing the
DOM, adding slick animations and effects to elements, and super simple
Ajax techniques and methods. Perhaps the jQuery home page describes jQuery most accurately:
jQuery is a fast and concise JavaScript Library that
simplifies HTML document traversing, event handling, animating, and
Ajax interactions for rapid web development. jQuery is designed to
change the way that you write JavaScript.
Let’s briefly
go over some of the benefits and features of using the jQuery library.
It dramatically reduces the amount of code that needs to be written
compared to pure Javascript, which leads to less development time and
more readable code. We will go over some example code later on in this
article.
It is (arguably) much easier to understand than scripting with pure
Javascript. In this world, the quicker and easier it is to finish the
development process the more time we have to focus on other goals.
The documentation is extremely well organized and the community is
very active with helping out anyone who may be struggling with a
snippet of code.
It makes using Ajax extremely easy, it only takes about 5 lines (sometimes less!) of code to make a simple Ajax call.
A wide range of plugins and extensions have been developed for
jQuery to make it easy for you to get the exact functionality you are
looking for.
There are many useful Web development tools that integrate in your browser. These in-browser tools are commonly known as add-ons or extensions. Though add-ons and extensions aren’t just
for Web development, many of them out there are designed specifically
for Web developers. In-browser tools vary greatly in the jobs they
perform; for example, some of them help you diagnose issues with CSS,
HTML and JavaScript, while others evaluate the accessibility of your
website.
In this article, we explore some of the most popular and useful in-browser Web development tools.
You’ll find tools for popular Web browsers like Firefox and Internet
Explorer. Whether you need to debug and inspect your HTML, inspect HTTP
headers, access FTP source files, evaluate accessibility or just figure
out what color a Web page element is, you may find a variety of tools
discussed here useful.
AJAX has gotten more and more popular over the years, and has allowed
web applications to act more and more like desktop applications. AJAX
can provide a lot of additional functionality that could not be
accomplished any other way. AJAX stands for Asynchronous JavaScript and XML. It is used for
allowing the client side of an application to communitcate with the
server side of the application. Before AJAX, there was no way for the
client side of a web application to communicate directly with the
server. Instead, you would have to use page loads. With AJAX, the
client and server can communicate freely with one another.
When creating a website, one main goal is to attract visitors. Traffic
generation is a necessity for monetary purposes, showing off your work,
or just expressing your thoughts. There are many ways to create traffic
for your website. Search engines, social bookmarking, and word of mouth
are just a few examples. But how do you know whether this traffic is
genuine? How do you know if your visitors are coming back for a second
time?
These questions have raised the concept of web statistics. Often times,
webmasters use certain programs, such as Google Analytics or Awstats,
to complete this job for them. These programs obtain a wide variety of
information about visitors to a site. They find page views, visits,
unique visitors, browsers, IP addresses, and much more. But how exactly
is this accomplished? Follow along as we present a tutorial on how to
create your own web statistics program using PHP, JavaScript, AJAX, and
SQLite.
Quite a lot of devices arrived on the market over
the past couple of years advertised as “iPhone killers,” but, in the
end, the only true iPhone killer we've seen up until has been the
iPhone 3G, which drove its predecessor out of the market. So, calling
Toshiba's new TG01 an “iPhone killer” might be a little premature, but
the truth of the matter is that this thing has enough attractive
features under the hood to represent at least a worthy challenger for
Apple's device.
GPS systems have become a pretty common fact
lately, especially since people have started rediscovering nature and
geotagging has become a worldwide sport. Of course, as GPS is so much
in-fashion lately, there are also quite a few companies aiming to
redesign their most successful computers. In Dell's case, that's the
Mini 10 netbook. That's why it is planning to offer the new Dell Wireless 700 location solution, a
combination of hardware and software bringing GPS locating to your Mini
10.
