IN THIS CHAPTER
The last of the basic components of WAP application construction is input from the user. You've already seen how to navigate between cards and create both text and image output. This chapter will focus on letting the user react to those cards and direct your application to take actions.
I will begin by covering WML card variables in detail; they are the heart of dynamic information handling in the browser. Next, I will walk you through using the tags that create input widgets—some that are free form and some that restricted the content that the user must supply. Finally, I will show you how to direct the browser to deliver the information back to your application.
