About Built-in scripts

You can configure one of each type of built-in scripts for a layout. There is no requirement to configure built-in scripts. Unconfigured scripts are not used at runtime and do not generate errors or warnings.

Built-in scripts are named for their trigger type, and cannot be renamed or deleted. A built-in script is not triggered by an expression, but instead uses the state of the layout to define when the script executes. The built-in scripts are::

• On Show: The script runs one time when the layout opens.

• On Hide: The script runs one time when the layout closes.

• While Showing: The script runs periodically for as long as the layout remains open.

For details about the Script Editor, see Build layout scripts. See also About the MyContent namespace for information about referencing different content contained in the layout.

Note: The three Built-in Scripts, each named for a trigger type (On Show, While Showing and On Hide), cannot be deleted from the script list. Only one built-in script per trigger type can be configured for a single layout.
