A scripting language is a tool which is used for functionailty to other software. The programming languages that use scripting languages are Javascript, PHP, Python, etc. It is designed for the purpose of creating simple tasks.An example could be when a
user types a product name into a search bar and the computer displays the most
relevant items on the website. It is a message from the user to the computer. Interactivity
is not only useful but it is now expected by customers. Static websites have
only fixed information on it, if it is to be changed then the designer needs to
change the code and then upload the amended page to the web server. These
websites are seen as old fashioned and useless because it wastes a lot of time.
Today, users
prefer using dynamic websites where it is updated live online, usually there
are scripting languages or databases. Dynamic websites are easy to maintain
once they go live on the internet, this means once a website is uploaded to be
viewed on the internet.
A scripting
language is normally used in conjunction with another programming language,
because of this you will often find it alongside Java. It is
easier to write the code in a scripting language than in a recorded language.
However, scripting language are slower because the instruction are not handled
solely by the basic instruction processor. A normal programming language
such as C++ is collected into an executable file, however a scripting language
reads one command at a time rather than being collected
Scripting
languages are mainly used to add functionality and interaction to a webpage.
JavaScript is a interpreted computer programming language, which was created by
Netscape. It was originally designed as part of web browsers so that client
side scripts could interact with the user, control the browser and alter the
document content that was shown. JavaScript was created with the exact purpose
since HTML did not have the capability of providing the full experience of interactive
websites alone, so JavaScript was joined to make the websites interactive
The main
difference with a scripting language and a programming language is the way they
are used. Scripts are typically quick whereas a programming language is meant
to be more thought out and deliberate. Scripting languages are languages that
do not need complication. A script is code part, rather than a complete or
standalone application. An example includes code in a webpage.
Client Side Scripting
Client side
scripting is used to make web pages change after they arrive at the browser. It
is useful for making web pages a bit more interesting and user friendly. It can
provide useful gadgets such as calculators, clocks, etc. As the code is being executed on the user’s computer, a possible
entry point for hackers is opened up.
Server Side Scripting
Server side
scripting is often used for allowing users to have individual accounts and
providing data from databases. It allows a level of privacy, personalisation
and provision of information that is very powerful. E-commerce and social
networking sites all rely on server side scripting to keep information safe.
Javascript
Javascript
JavaScript
is an interpreted computer programming language. It was originally made as part
of web browsers do that client side script could interact with the user,
control the browser, and alter the document content that was displayed. JavaScript is a scripting language and it gas
a wide range of applications including e-commerce and advertising networks such
as Google AdSense.
JavaScript
plays a obvious role in displaying adverts on websites. It controls which ads
are displayed and may set a cookie on your computer which indicates you have
seen the advert, JavaScript is also used to open windows for pop up adverts
unless your browser restricts it.JavaScript
is extensively used for e-commerce sites. It plays a huge part is such tasks
such as adding items to your shopping cart, processing forms and submitting
orders to be shopped. It can also be used to show dynamic content to users while
shopping such as related items you have seen.
JavaScript is
also used to display simple alerts to users for example if you fill out a form
and type in a invalid address, an alert will appear saying there has been a
mistake. JavaScript is also used for security. Some login systems need you to
type in your password using a onscreen keyboard.
jQuery
jQuery is a
coding language that is from JavaScript. jQuery works like JavaScript where it
is used to help with interaction and effects with your development code. jQuery
hasn’t been around for a long time, it was released in the year 2006 and the
only version is 1.4.0. jQuery is new and an exciting technology which catches
on quickly and makes the internet more interactive and enjoyable. With jQuery, you can accomplish effects with less code that it
would take with JavaScript. Most common jQuery effects are drop down menus,
drag and drop elements, animation and form validating. Developers have
connected his with other coding language such as JSP, ASP, PHP, and CGI
With languages that are event driven, the code is broken in to events
so it could be any action for example the most used one is the click of the
mouse. When the mouse is clicked then the code is triggered into running when
the action happens Events are actions, which script sense, and when it is
sensed a reaction occurs. Events can include a mouse button being clicked or a
keyboard key being pressed. Old browsers do not support scripting languages.
Browsers that can interpret will see the <script> tags and interpret the
code between them. Browsers that cannot interpret the script will ignore the
script tags and also the HTML comments
