A simple program or sequence of
instructions that is carried out by another program. All sorts of programs
use scripts as a way of automating procedures or carrying out simple tasks.
Many communications programs, for example, use scripts to control the login sequence by
automatically sending a username and password when prompted by the
host computer.
The most common use of scripts in the web environment
is to control web pages, either in the browser or on the server.
Scripting languages such as Javascript and JScript are designed to
slot into standard html code and provide features beyond those of the
mark-up language itself, such as checking the status of web forms or
changing the appearance of some page elements when a button is pressed. The
scripts that are written for these functions are interpreted directly by the
browser, without any need to pass data back to the server for processing. |
