So the result is? Case AFrom 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.
