Scripting and Interactivity
HTML code creates static
Web pages. Inserting
scripts makes your pages
dynamic.
Two common uses for scripts
are:
• To insert changing
information into a Web page.
• To allow interactivity.
script A short program that
you can insert into HTML
code using special tags;
expands the capabilities of
HTML to create dynamic
Web pages. (p. 268)
interactivity Allows
communication between the
visitor and the Web page;
the user can perform an
action that the Web page
responds to. (p. 268)

Interactivity Design Guidelines
Here are some design guidelines for using interactivity:
• Use interactivity only when it enhances the site.
• Maintain simplicity.
• Make certain users understand the response expected of them.
• Check interactive components in all the browsers your visitors
are likely to use.

Scripting Languages
Each scripting language is
designed for specific
types of interactivity:
JavaScript
Java Applets
Common Gateway
Interface (CGI)
DHTML
JavaScript A scripting language
used to enhance the capabilities of
Web programming by allowing the
creation of special effects such as
fading backgrounds and button
rollovers. (p. 269)
Java applet A short Java code
program that runs in a browser. (p.
270)
Common Gateway Interface
(CGI) A type of script that provides
a link, or interface, between an
external application and a Web
server. This link allows the Web
server to pass a user’s request to
an application program and then
return information to the user.

Markup Languages
HTML is a markup
language that defines the
appearance of data.
Extensible Markup
Language (XML) tags
impose a structure without
providing attributes on
how the data are to be
displayed.
XHTML is the bridge
between the HTML and
XML.
markup language A text file
that contains special
sequences of characters that
function as tags, such as
HTML, XML, and XHTML.
(p. 270)
Extensible Markup
Language (XML) A markup
language whose tags impose
a specific structure and
meaning on data without
providing any information
about how the data should
be displayed. (p. 270)

Using the DHTML Effects Toolbar
FrontPage makes adding DHTML effects easy by using
the DHTML toolbar.
• The first menu (On menu) allows you to specify the event, or
action, that will trigger the effect.
• The second menu (Apply menu) allows you to choose the effect
you want to add to the page.
• The third menu allows you to further refine your request.

Marquees
You can create marquee
text that slides in once
and then stays put,
repeats a specified
number of times, or
continuously repeats.

Rollover Buttons
FrontPage uses DHTML
to create a rollover
button. You can create a
rollover effect by inserting
interactive buttons on a
site.

that changes appearance
when the mouse pointer
passes over it. (p. 276)

Update Information
Web developers often use scripting to display the current
date. News sites usually display the current date to let you
know that the site’s content has been updated.
In addition, many search engines allow you to search for
sites that have been updated within a specific time frame,
such as the last six months.

Adding a Form to a Web Site
Forms and Their Components
Web programmers and
designers use forms,
made up of fields and
labels, to allow users to
enter and submit data.
Most forms also contain a
Submit and Reset button.
form A structure that
includes fields for collecting
data from visitors to a Web
site. (p. 281)
field A form component that
allows the user to enter
information into the form. A
form field often corresponds
to a field database. (p. 281)
label Text that tells the user
what type of information to
enter into a form’s field.
