PROJECT OVERVIEW
The Web page created in this project serves as a notice to Fun with Phonics customers indicating
that the Web site has moved to a new location. In creating this project, students learn how to
modify a Web page using the Notepad text editor. They learn how and where to place JavaScript
code on a Web page. The project introduces the concepts of creating new objects by defining
variables, such as with the Date() object. Students learn the rules for naming variables and how
to extract only the date from the user’s computer system. Students learn how to write a userdefined function that calls the built-in alert function to display a message. Students learn how to
embed HTML codes within JavaScript code and to format displayed text in the document.
Students learn to use the setTimeout() method to call a JavaScript function.

Exploring Online Documentation
1. JavaScript is Netscape's cross-platform, object-based scripting language for client and
server applications. JavaScript lets you create applications that run over the Internet.
Client applications run in a browser, such as Netscape Navigator, and server applications
run on a server, such as Netscape Enterprise Server. Using JavaScript, you can create
dynamic HTML pages that process user input and maintain persistent data using special
2 a.
b.
c.

objects, files, and relational databases. Through JavaScript's LiveConnect functionality,
your applications can access Java and CORBA distributed-object applications.
JavaScript
Java — Objects are divided into classes and instances with all inheritance through the
class hierarchy.
Java
JavaScript
JavaScript
Using JavaScript entities, you can specify a JavaScript expression as the value of an
HTML attribute. Entity values are evaluated dynamically. This allows you to create more
flexible HTML constructs, because the attributes of one HTML element can depend on
information about elements placed previously on the page.
JavaScript entities also start with an ampersand (&) and end with a semicolon (;). Instead
of a name or number, you use a JavaScript expression enclosed in curly braces {}. You
can use JavaScript entities only where an HTML attribute value would normally go. For
example, suppose you define a variable bar Width. You could create a horizontal rule
with the specified percentage width as follows:
J 1.10
JavaScript Instructor’s Materials J 1.11
<HR WIDTH="&{barWidth};%" ALIGN="LEFT">
As with other HTML, after layout has occurred, the display of a page can change only if
you reload the page. Unlike regular entities that can appear anywhere in the HTML text
flow, JavaScript entities are interpreted only on the right-hand side of HTML attribute
name/value pairs. For example, if you have this statement: <H4>&{myTitle};</H4> It
displays the string myTitle rather than the value of the variable myTitle.
4. Use the <NOSCRIPT> tag to specify alternate content for browsers that do not support
JavaScript. Browsers that do not support JavaScript display HTML code enclosed within
a <NOSCRIPT> tag; Navigator ignores code within the tag. Note however, that if the
user has disabled JavaScript from the Advanced tab of the Preferences dialog, Navigator
displays the code within the <NOSCRIPT> tag.
5 a. Functions are one of the fundamental building blocks in JavaScript. A function is a
JavaScript procedure — a set of statements that performs a specific task. A function
definition has these basic parts: the function keyword, a function name, a commaseparated list of arguments to the function in parentheses, and the statements in the
function in curly braces.
b. Defining the function simply names the function and specifies what to do when the
function is called. Calling the function actually performs the specified actions with the
indicated parameters.
c. Generally, you should define the functions for a page in the HEAD portion of a
document. That way, all functions are defined before any content is displayed. Otherwise,
the user might perform an action while the page still is loading that triggers an event
handler and calls an undefined function, leading to an error.
6. The write method of document displays output in the browser. "Big deal," you say,
"HTML already does that." But in a script you can do all kinds of things you cannot do
with ordinary HTML. For example, you can display text conditionally or based on
variable arguments. For these reasons, write is one of the most often-used JavaScript
method.
