Preface:On WCF -5: Duplex Communication in WCF Message Exchange Mode (Duplex) in the blog post, I explained a scenario for the duplex Communication Service, the subscription and release model, which , I'll explain how a WCF client creates a

Think of a problem first: a time-consuming operation such as SetTimeout, Ajax requests, and so on, we need to execute a function done after the delay operation.Like what:　var function () { varfunction() {alert ("execution

UsedC ++TargetedObjectUsers of programming know that objects in a program rarely exist independently. It is almost impossible to ignore the interaction between objects. Therefore, it is an important task of object-oriented programming to identify

jquery provides developers with external interface calls, but $. The callbacks () module is developed to give internal $.ajax () and $. The Deferred () module provides a unified basic functional component. It can be used as a function of a new

In Cocos2d-lua, there are many asynchronous or deferred operations, such as background loading of pictures, waiting for a certain amount of time to execute code, and so on. Functions of these functions typically require the passing of a function as

Typically, we create an object and immediately go directly to the method that uses it. In some cases, however, you want to be able to invoke a method of this object after a scene has occurred or when the condition is met. The callback will resolve
