Enabling Java and JavaScript

The Need for Java Enablement
The Quizzing section of this product contains over 6000 quiz questions. These questions are presented using Java technology. You need not know anything about Java, but your browser must have its Java option enabled. Otherwise, the quizzes won't work.

The Need for JavaScript Enablement
The "left navigational" panel in the web site includes a variety of links. Each of these links is colored white in its unselected mode, and is colored yellow when selected. For instance, if you click on the number "1" in the "choose a chapter" table, you will be taken to the content for chapter 1, and the number 1 will remain yellow until you choose another number from the "choose a chapter" table. This yellow highlight color behaves as it does because of JavaScript. If you don't have your browser's JavaScript option enabled, the highlight won't work.

Enabling Java and JavaScript
Below is information on how to check (and if needed enable) the Java option and the JavaScript option in the Macintosh version of Internet Explorer 4.0 and Netscape Navigator 4.08. The information may change slightly on newer versions of these browsers.

Internet Explorer 4.0
Internet Explorer supports Javascript internally, and there are no options that you as a user can turn on and off when it comes to JavaScript. Thus, if you are an Internet Explorer user, JavaScript is automatically enabled. As for checking for Java enablement, here are the steps:

Select "Preferences..." from the "Edit" menu.

An "Internet Explorer Preferences" dialog box will appear. Click on "Java" in the scrolling list of topics. Below is a screen capture of the contents of this dialog with "Java" selected.

Ensure that the "Enable Java" box is checked and then click on the OK button.

Netscape Navigator 4.08

Select "Preferences..." from the "Edit" menu.

A "Preferences for Nav 4.08" dialog will appear. Click on "Advanced" in the scrolling list of topics. Below is a screen capture of the contents of this dialog with "Advanced" selected.

Ensure that the "Enable Java" and "Enable Javascript" boxes are checked and then click on the "OK" button to close the dialog box.
