Components

Note: Keep the same prefix throughout all the files that correspond to one component so that each file and its

corresponding component can be identified easily.

2 Write the JavaScript code to implement the new server component.

The extension file (HTM) defines the locations of the JavaScript code in the SCRIPT tag. These JavaScript files can

reside in the Shared folder, in the same folder as the extension file, or in the Common folder for code that applies to

multiple server models.

For example, the WebServices.htm file in the Configuration/Components/Common/WebServices/ folder contains the

line:

For more information on the available Component API functions, see “Components panel API functions” on

page 312.

When adding a new service, you might want to use the Components panel to browse meta information so that the

information is readily available as you create the extension. Dreamweaver can browse added components and display

nodes in the component tree. The Components panel provides drag-and-drop support and keyboard support in Code view.

Properties of tree control

Use the ComponentRec property to populate a Components panel tree control, so that it appears within the

Components panel in the proper location. Every node in a tree control must have the following properties:

Filename Description Required/Optional

*.htm The extension file that identifies other supporting JavaScript and

GIF files.

Required

*.js The extension file that implements the Component API callback. Required

*.gif The image that appears in the Components pop-up menu. Required

*Menus.xml The repository for metadata that organizes the Components panel

structure. Although the common WebServices component does

not use this file, you can refer to the file WebServicesMenus.xml in

the application folder Components/ColdFusion/WebServices as an

example.

Optional

*.gif Toolbar images, which can be enabled or disabled, as shown in the

following example:

ToolBarImageUp.gif

ToolBarImageDown.gif ToolBarImageDisabled.gif

or, tree node images.

Optional

Property name Description Required/Optional

name Name of the tree node item Required

image Icon of the tree node item. If it is not specified, a default

icon is used.

Optional

hasChildren Responds to clicks on the Plus (+) and Minus (-) buttons in

the tree control by loading children. You can work with a

tree that is not prepopulated.
