The Yahoo! UI Library (YUI) offers a range of widgets and utilities to bring modern enhancements to your traditional page elements. In this chapter, we will look at a selection of these enhancements, including features often seen on modern interactive interfaces, such as:
Auto-complete: This feature suggests possible values to the user by searching against a list of suggestions as they start typing. We will look at two different ways of using this. First, by providing suggestions as the user types into a text box, and second, by providing a list of possible values for them to select from a combo list box.
Auto-update: This technique will allow us to update an area of the page based on a timed interval, which has many uses as we'll see. In this example, we will look at how to create a clock by updating the time on the page at one second intervals. This technique could also be used, for example, to update a news feed every minute, or update stock information every hour.
