In this chapter we will:
• Introduce the AJAX family of tools
• Use jQuery's built-in AJAX support to get content from Drupal
• Fetch existing XML content from Drupal
• Use additional Drupal modules to expose more data to AJAX
As you may have noticed, our earlier chapters were heavy on explanation. Projects were used to simply illustrated the main points. Gradually, projects have gotten bigger, and the explanatory text has taken up a secondary role. In this chapter, we will spend most of the time looking at code and creating projects. First, we will have a quick overview of AJAX and how it fits into the Drupal landscape.
