Hereis an explanation of key passages in the preceding code listing:
234-243: Application- and component-level custom attributes; remember to
use meaningful names to describe them rather than their attribute number. It
may also be helpful to put a comment on expected values when applicable so
that other developers know what values to expect.
250-253: Variables to store the affected elements; generally, in dynamic action
plug-ins, this information is required only in the JavaScript code (which can be
referenced in the
this
object). Due to the requirement of hiding the object on
page load, the affected element is required here. This will be discussed further
in the code analysis.
257-266: Inline function to convert Y/N values to true/false (string) values; this
is not required, but if you need to convert some of the same types, attributes
creating inline functions can save time.
