Scripting Individual Elements

Scripting Individual Elements

Chapter 8, "Scripts and Elements," introduced scripting elements in Dynamic HTML. While every element in an HTML document is accessible to scripts, this chapter focuses on techniques for programming a few of the elements that appear most commonly in scripts. Chapter 10, "Forms and Intrinsic Controls," describes techniques for programming elements in forms.

The following topics are covered in this chapter:

• Programming the Body and Frameset elements HTML defines two types of documents: documents with Body elements for displaying contents, and documents with Frameset elements for dividing the screen into frames for loading other documents. This section introduces techniques for manipulating these elements.

• Programming the Anchor element Anchor elements serve a dual purpose in HTML: as links that navigate to new pages, and as bookmarks that act as destinations. This section discusses how to manipulate both types of Anchor elements and how to add custom behavior to them.

• Programming the Link element The Link element is used to define relationships between documents. Microsoft Internet Explorer 4.0 supports the Link element for specifying linked style sheets. This section shows you how to define and take advantage of custom relationships between documents.

• Programming the Image and Map elements Dynamic HTML exposes a rich object model for manipulating images and image maps. New images can be loaded in the background so that they can be displayed instantly, and image maps can be dynamically modified and scaled.

• Programming the Marquee element The Marquee element is currently an Internet Explorer-specific feature used to automatically scroll a block of text. The Marquee element can be customized and manipulated using the Dynamic HTML object model.

• Programming the Object element The Object element is used to embed custom contents, including ActiveX controls and Java applets, in the HTML document. The custom contents can expose a customized object model alongside that of the Object element. This section shows you how to access this object model.

• Programming the Table element Tables are used for two purposes: displaying tabular data in a gridlike format, and creating a sophisticated layout. This section discusses the relationship between the underlying HTML for the table and the object model representation.
