Inside JavaScript

The <OL> Element: Ordered Lists

You create ordered lists, which display numbered or lettered items, with the <OL> element. (Note that we just saw such a list in Listing 14.3.) You create each item in the list with an <LI> element. Here's an example that displays such a list:

(Listing 14-06.html on the web site)

<HTML> <HEAD> <TITLE> An Ordered List </TITLE> </HEAD> <BODY> <H1> Creating An Ordered List </H1> Buying a computer? Let's consider: <OL> <LI> Price <LI> CPU Speed <LI> Memory <LI> Disk space <LI> CD-ROM/DVD speed </OL> </BODY> </HTML>

You can see the results in Figure 14.2.

You can find the JavaScript properties for the <OL> element in Table 14.3. Remember that JavaScript's core HTML properties, methods , and events, which we covered in Chapters 5 and 6, apply to this element as well.
