We felt enlivened by this unexpected output.He mobilized the New York Times to rescue Hu Shi from prison, which is rarely mentioned in domestic historical works. When Hu Shi was the principal of China Public School, he was finally arrested for offending the national government by repeating three important articles in New Moon. As news came that he would be shot, Aban was furious and mobilized the Times headquarters to publish a long editorial condemning the atrocities committed by the national government. He quickly translated the editorial into Chinese and Japanese, spending a lot of money, and sent the editorial to all Chinese, Japanese and English newspapers and magazines in the Far East by telegram for reprinting, forming a trend of overwhelming condemnation, finally forcing the national government to withdraw the butcher's knife and release Hu Shi.Iterator patterns are created for collection objects, For collection objects, It must involve the addition and deletion of collection elements, and certainly supports the operation of traversing collection elements. If the traversal operation is also placed in the collection object at this time, the collection object will bear too many responsibilities. At this time, the responsibilities can be separated and the traversal of the collection can be placed in another object, which is the iterator object.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. Let's look at the following code:
