24 browsing employees
In the previous chapter, we created the non-Ajax parts of the employee browsing
pages. Although the focus in this book is on Ajax, it??™s very important to
have working, non-Ajax components in place for those who can??™t take advantage
of the lovely Ajax interface. In this chapter we??™ll place the Ajax layer on
top of the existing one.
The Ajax components consist of three fi les: one JavaScript fi le that will provide
all-purpose, browser-safe Ajax functionality; another JavaScript
fi le that will provide page-specifi c functionality; and one PHP script that
will handle the server-side needs of the Ajax layer. To make these additions
active, the main HTML form will be slightly modifi ed as a last step.

what we??™ll do
1 First, on pages 27-28, we??™ll create a JavaScript fi le that makes a browserspecifi
c supported Ajax object. That object will be used by any page requiring
Ajax functionality.
2 On pages 29-31, a second JavaScript fi le that defi nes the functionality
specifi c to the employee-browsing aspect of the example will be started.
