Of CGI And Java Scripts
Author: Andrew Corner
CGI and Java Scripts are both functional with both Netscape and
Internet Explorer browsers. But there is an essential difference
between the two. Java functions as a code executed and
downloaded in the clients' side while CGI operates with the
server. Before probing deeper into the difference of the two,
let us first try to understand these two often-used scripts.
Java Script requires no special plug-ins, and it works
transparently within an HTML page. It animates web page
graphics, allows users to change page elements (background
color, display preferences), and allows site navigation.
Usually, Java Scripts are made up of two parts: the Java Script
functions (the instructions for what the Java Script does on the
page) and elements that cause the Java Script functions to
execute. These two go in different ways. The Java Script
functions are placed between special Java Script tags within
the head tags in the HTML source. Java Scripts follow specific
punctuation conventions. Usually, Java Script functions are the
last element within the head tag. The elements that cause the
Java Script to execute are placed within the body tags of the
HTML source, depending on where the web page designer wants the
Java Script to run. Because Java Script is included in the other
HTML tags in the page source, a web page with Java Script
elements will be saved in exactly the same format as a web
page: the file type should be an ASCII text, and the file name
should have the suffix .html appended to the end of it. The
script's difference from CGI will not be clear unless we
discuss both CGI and Java Scripts.
CGI is the short version of Common Gateway Interface. It is
commonly used in web pages because it allows interactivity by
letting the web server respond to user input through a web page
with CGI elements. A common example of CGI function is a web
guest book. A web designer usually includes a web guest book in
the web page so users and visitors can put in their suggestions.
These suggestions are collected by the CGI and e-mailed to the
designer. CGI and Java Scripts also have a similarity. Like in
a Java Script, files used in CGI must be ASCII text with the
suffix .html appended to the end of it. However, if a CGI
script will be stored in the CGI bin, it is most likely that
the file must be saved as a Perl document. Unlike Java Script,
where the functions must reside within the head tags, form
elements can be placed wherever the web page designer wants to
put them. The only consideration is that to call the CGI
script, HTML tags should come before the form elements of the
page.
Though both scripts have different functions, both CGI and Java
Scripts have undoubtedly improve the way the internet works.
They have also infiltrated the world of movies and televisions
with digital films and fantastic characters. Who knows, maybe
more uses of both scripts will be identified in the future.
