Subject class, accept method, accept the object that will be accessed, getSubject () gets the property that will be accessed,From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed.
