The JavaScript event proxy (event delegate), which is to delegate events that would otherwise be bound to the parent element, so that the parent element acts as an event listener.As we all know, DOM operations are very performance-intensive. So duplicate event bindings are simply performance killers. And the core idea of the event agent is that by tying as little as possibleTo monitor as many events as possible.The core idea of event broker: Event bub

Broker modeEncapsulates a series of object interactions with a mediation object. The mediator makes the objects not need to explicitly reference each other, so that they are loosely coupled, and can independently change the interaction between them. There are many examples of intermediaries, from the United Nations Security Council to housing intermediaries, who have played a central role in coordinating the interests of all parties.ExampleThis articl

Broker Mode:The Mediator pattern (mediator pattern) Definition: A Mediation object encapsulates a series of object interactions so that the intermediaries do not need to explicitly reference each other, so that they are loosely coupled and can independently change the interaction between them. The mediator pattern, also known as the mediator pattern, is an object-behavioral pattern.Mode motive:1. In the design of direct chat between user and user, the

Mediator Mode (mediator): Uses a Mediation object to encapsulate a series of object interactions. Intermediaries are objects that do not need to explicitly reference each other, so that they are loosely coupled and can independently change their interactions.The broker pattern is easy to apply in the system and is easily misused in the system. When the system appears many-to-many interaction complex object group is, do not rush to use the intermediary

What is the broker mode?Mediator mode: A third-party mediator communicates between objects and objects.definition: Using a Mediation object to encapsulate a series of object interactions, the mediator makes the objects do not need to explicitly reference each other, so that they are loosely coupled, and can independently change the interaction between them.The main solution: There is a large number of relations between objects and objects, which will

CORBA (Common Object Request Broker architecture) is a new technology developed with the rapid development of software and hardware resources today. It allows distributed applications to complete communication, regardless of the manufacturer of the application, and can communicate with each other as long as the CORBA standard is met.
