3. browsing using Ajax
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 files: one JavaScript file that will provide all-purpose, browser-safe Ajax functionality; another JavaScript file that will provide page-specific 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 modified as a last step.
