how the Text Field is nested within the <label> tag. Doing this creates a simple association between the Company text and the Text Field form element.           Summary This chapter is the beginning of a higher level of web development. Creating forms to interact with an end user really starts to show the strengths of the web and offers endless possibilities. As you get deeper into this book, you'll start building forms that interact with server-side applications. As you'll see, forms, in conjunction with server-side applications, begin to push the envelope for more engaging experiences for web users.           Chapter 10. Using Dreamweaver Behaviors IN THIS CHAPTER An Introduction to Dreamweaver Behaviors Using the Behaviors Panel Dreamweaver Behaviors As we've progressed through the book, we've touched on topics such as client-side web pages and server-side applications. In the previous chapter, we mentioned that HTML forms are the stepping stone for working with server-side applications but still remain an integral part of client-side web page development. What we haven't touched on, however, are the three building blocks that make up client-side web pages or the functionality and look with which the end user interacts. At the foundation of client-side development lies the first block, HTML/XHTML. Everything we do on the web, to a certain extent, revolves around HTML/XHTML. Dreamweaver, by definition, is a tool for creating HTML/XHTML pages for the web. The second building block, discussed in some detail in Chapter 7, "Advanced Page Formatting Using Style Sheets," is CSS. As we've seen, style sheets control the overall look and appearance of HTML/XHTML pages and again, are significantly supported by Dreamweaver. The third and final block to client-side web page development, JavaScript, has yet to be discussed. At its heart, JavaScript exists as a web-based scripting language. While HTML/XHTML defines the structure of our client-side web pages and CSS controls the "look" of our web pages, JavaScript exists to outline the logic that our web pages will have in the form of a full-blown interactive scripting language similar in nature, but independent of, the object-oriented programming language Java. For instance, you may want to add functionality to your web page that otherwise wouldn't be available through HTML or CSSsuch as creating a pop-up message, a pop-up window, a pop-up menu, or even image-based rollovers for a navigation menu. Even better, you might want to add functionality to the helpdesk.htm page that guarantees that users enter text into all required
