WAP Development with WML and WMLScript

Chapter 10. Using Timers

IN THIS CHAPTER

• The Timer Element

• Defining a Timer's Action

• Practical Examples of Timers

In WML, you can create a timer that counts a defined length of time, after which it initiates a predefined action. This chapter shows you how and when to add timers to your WML code using the various parts of a timer element. You will also learn a shorthand way to code timers, instead of a longer, more complex method that can give your timers greater functionality when needed. This chapter provides some advanced examples of timers, discusses practical applications of timers, and finally compares timers to alerts.
