Spry objects
Spry is an Ajax (Asynchronous JavaScript and XML) framework developed by Adobe. The Spry objects in
Dreamweaver make it easy to apply the more powerful facets of Ajax, including the capability to update
data in a portion of the page without refreshing the entire page.
The Spry category of the Insert bar, shown in Figure 3-21, is divided into three groups: data, forms, and
layout. As noted earlier, these objects are also available from each of the Insert bar??™s corresponding categories.
The Dreamweaver team decided to take this multiple access approach to both highlight the new
Spry technologies and emphasize where the various components fit in the Web designer??™s workflow.

You??™ll find a full chapter devoted to the world of Ajax and the Spry implementation in Chapter 18,
???Powering Ajax Pages with Spry.???
The Spry data objects work with associated XML files to selectively display just the data requested by the
user. The first object in the group, Spry XML Data Set, establishes the XML connection, while the others
implement the display of the data. Table 3-2 details the individual Spry data objects.
