CHAPTER 18 USING THE BUTTON, PROGRESS BAR, AND SLIDER WIDGETS Figure 18-22. Responding to slider events Summary In this chapter, I introduced you to the first three jQuery UI widgets: the button, the progress bar, and the slider. Each widget follows the same basic structure. There is a single method that creates and configures the widget as well as letting you supply functions that will respond to its events. Some methods and events are common to each widget, but there are unique additions as well that expose the special functionality that some widgets offer. Now that I have gotten the basics out of the way, I'll show you some more flexible and complex widgets in the chapters that follow. 511
