Understanding the Spry framework

From: Dreamweaver CS3 Beyond the Basics

Video: Understanding the Spry framework

In this chapter, we will examine one of the most anticipated additions to Dreamweaver CS3, the integrated Spry framework. Adobe Spry framework is not new, in fact, the previous version of Dreamweaver supported hand-coding Spry, but in CS3, Adobe has added Spry framework tools to Dreamweaver's interface, which will greatly simplify adding Spry functionality to our pages. Now, before we get into actually adding Spry elements to our page, let's have a brief overview of what Spry is. Spry is the name for Adobe's JavaScript AJAX library and the associated effects. Dreamweaver CS3 ships with Spry 1.4, but Adobe is constantly updating it, so be sure to go to Adobe Labs to check to see if you have them as current version.

Understanding the Spry framework

In this chapter, we will examine one of the most anticipated additions to Dreamweaver CS3, the integrated Spry framework. Adobe Spry framework is not new, in fact, the previous version of Dreamweaver supported hand-coding Spry, but in CS3, Adobe has added Spry framework tools to Dreamweaver's interface, which will greatly simplify adding Spry functionality to our pages. Now, before we get into actually adding Spry elements to our page, let's have a brief overview of what Spry is. Spry is the name for Adobe's JavaScript AJAX library and the associated effects. Dreamweaver CS3 ships with Spry 1.4, but Adobe is constantly updating it, so be sure to go to Adobe Labs to check to see if you have them as current version.

Now, since Spry is an AJAX framework, let's discuss what AJAX is. AJAX stands for Asynchronous JavaScript and XML. Basically, JavaScript is used to refresh XML or other data on the page without needing a browser refresh. Looking at our current slide, we have an XHTML page, which uses the JavaScript library to process a request. It will then send that request to the XML or other data source, which will go back to the JavaScript and be refreshed into the XHTML page, all without needing a browser refresh. So this test is for us to actually use the Spry framework in Dreamweaver, we define a data set, we then use Spry Elements to display the data on the page.

We can further enhance that by using Spry widgets and effects to add increased interactivity. Before we get into exercises, let's take a look at the finished file to see exactly what we will be doing. So here we are in the browser and we are previewing the CHEEK CHASTAIN CURRENT SHOW page. Now, I am going to scroll down just a little bit so that we can actually see the finished version of this. This file is available in your Exercise Files, if you are following along. They are in the Chapter 5, Spry Directory, and the name of the file is current_final.

Well, on the left hand side of the page, we have a table that says Painting and Price. So these are the paintings under the Current Show and their prices. Notice that if I click on Price, we actually change the sorting order of the table. If I click on Painting, we change the sorting order of the painting by the painting's name. As I hover over, I get a Hover Effect over each of these. If I click on them, then I get a Selected Effect. Now, what is that Selected Effect actually doing? Well, more on that in just a moment. Now, below that, we have a list of Past Shows, and this is the Past Shows for our current author. Now, that doesn't look all that impressive, but it's coming from an XML file, so we are not actually using a database for that or we are not having to hand-code it, we are letting Spry take care of that for us by just bringing this data in from an XML source.

Now, to the right of that we have what's known as a Spry widget. This is the Accordion widget. So it starts off with a Note from the Artist, but if I click the tab for Image, notice that it animates down to reveal a painting. Well, each of the paintings that are listed over here on the table, when I click on them, they will refresh and change the view and display another painting and any resulting information. If I click on Painting Info, it displays the info about that particular painting, and of course clicking on Note from the Artist will reveal that again. We have a nice animation effect between each of these, and each of the panes features a different height.

So these are the effects that we are going to add to the page. If you think about all the information that we have on this page, we have a list of paintings. We have the prices for that painting. We have the list of the past shows. We have an image of each painting. We have the medium and the date that it was completed. We have a description of the painting, and we have a note from the artist. Trying to display this on one page would be very, very difficult, you would usually break that up into multiple pages, but here we can see, using the Spry framework, using XML and JavaScript, we are able to do that in a very tight, compact space. So in our next exercise, we will take a look at defining a data source and then easy ways to get that data to display on a page.
