Now that you have the shell of the application created, you can move forward in ex-
tending it by adding other pages, regions, and items.
HTML Regions
The HTML
region
is one of the most basic and yet most flexible types of region. There
are three subtypes of HTML region, as shown in
Figure 5-19
:
•
HTML
: Any HTML tags render as their interpreted value; JavaScript ex-
ecutes as if part of the page source.
•
HTML Text (with Shortcuts)
: Like the HTML region, with the addition of
support for shortcut technology. This technology includes a shared com-
ponent object that can be used for managing a type of variable using
SHORTCUT_NAME
syntax.
•
HTML Text (Escape Special Characters)
: Shows HTML code as the source
value. Example:
<br />
will show up exactly as the code
<br />
rather
than being interpreted as a break / return.

HTML region subtypes
With the HTML region's simplicity comes a wide variety of uses. An HTML region
is a container that can have its own value, embedded JavaScript, or CSS definitions, or
it can contain other page items. Any valid HTML entered in the source renders on an
APEX page. Substitution-string syntax, such as
&ITEM_NAME.
, can also be used to
display item values in the source text.
