This invention discloses a menu display method,
system, device, medium, and product, belonging to the field of
computer software technology. The method comprises: an interface management component responding to an operation command, determining the target identifier corresponding to the operation command according to a mapping table in a
file management component, and determining an event message based on the target identifier; an
event management component
broadcasting the operation event message to all first menu components according to a monitored registry; a first menu component responding to the event message, matching the associated identifier with the target identifier, and if a match is found, sending menu information to the interface management component; otherwise, ignoring the match; and the interface management component rendering the menu information as a
context menu. Therefore, by implementing this invention, the
scalability of the menu display method and the pluggability of components in the menu display
system can be improved, resulting in low maintenance costs.
