Web Site Menus : Which Section Am I In?
By Stephen Bucaro
One way to increase the usability of your website is to use a navigation design that
web users are familiar with. For example, a navigation bar just below a website's header
is a common design used today. Clicking on a button in the navigation bar takes the user
to a different web page or different section of the website.
You can increase usability further by highlighting the button of the current section
in the navigation bar. This helps the user understand where they are within the structure
of your website. In this article you'll learn how to create a navigation bar, and how to
use a simple Java Script function to highlight the button of the current section.
Let's design a navigation bar with three buttons: "Home","About", and "Contact". The
navigation bar will be constructed using an html table. If you want to get some "hands-on"
experience, open your favorite basic ASCII text editor, like Windows Notepad, and type
in the html code shown below.

How Far Did the User Scroll?
From a reader; "I'm trying to find code snippet I can add to html pages so I can tell
how far a reader scrolled down in a sales letter before bailing and have that info show
up in a log or other file that is easy to get to. That way I know where people lose
interest in a sales letter or article so it can be changed to be more effective."
Let's see what we have in our Java Script bag of tricks. The html <BODY> tag has a
property, scrollTop that gives you the upper-left corner pixel location of the users
browser window. Along with the <BODY> tag properties clientHeight and
clientWidth this can give you the location of the pixel in the lower-right corner
of the users browser window, as shown below.
var st = document.body.scrollTop + (document.body.clientHeight * document.body.clientWidth);
But because of the flowing layout nature of a webpage, this value is of limited practical
use. The problem is that the user can change the size and shape of their browser window.
As the user adjusts the shape of their browser window, the text, images, and other elements
rearrange themselves as they flow into position on the webpage.
