Using the Scripting Object Tree
The Scripting Object Tree is a floating window that displays all objects and events available via Javascript. An object is a self-contained entity that consists of both data and procedures to manipulate the data, while an event is an action or occurrence detected by a program. This allows you to easily select the correct object or event for your Javascript coding.
To use the Scripting Object Tree:
Turn the Scripting Object Tree on or off by clicking on the View > View Script Object Tree menu option.
Open the tree and double-click on the required event or item to insert it into your web document.
