Code as above; Write three functions of order500, order200 and orderNormal respectively, and process their own business logic in the functions respectively. If their own functions cannot be processed, they will return the string nextSuccessor to pass it back, then encapsulate the constructor Chain, pass an object fn into it, and have their own attribute Successor. There are two methods setNextSuccessor and passRequest on the prototype. The method setNextSuccessor specifies the order of nodes in the responsibility chain, and saves the corresponding method to the attribute this.Successor, chainOrder500. SetNextSuccessor (chainOrder200); ChainOrder200. SetNextSuccessor (chainOrderNormal); Specifies the order in the chain, so this.Successor references the order200 method and the orderNormal method, so if chainOrder500.passRequest (1, true, 500) is called for the first time, the order500 method is called, output directly, and chainOrder500.passRequ is called for the second time.警界老油条阿辉（周润发 饰）生性风流，凭借自己父亲昔日手下沾叔（黄沾 饰）的维护，阿辉在警局虽然得不到升迁，但也落得清闲。新进警员曹里昂（李元霸 饰）的到来打破了这一切，曹大胆甚至莽撞的办案方式连累阿辉大出洋相，阿辉虽恨曹里昂，但碍于上司命令，不得不与曹搭档。抬眼看了看他，叹气道：大师兄把人都带走了，如今我们可忙了，连我娘都要出来坐堂。故事起源于一夜的错误，白富美女主和富商男主同时在各自的婚礼上被抛弃.他俩必须联手假结婚，然后互相解决一系列问题，患难生情，信任和真心使他们经受住重重考验。Germany: 760,000The conclusion of physical examination and appraisal is divided into:When the coil is energized, the iron core attracts the armature and the support plate to move down, and the contact points are turned on or off instantly. The piston rod and the lever slowly decrease due to the influence of the blocking nylon. After a certain period of time, the piston rod decreases to a certain position, and the delayed action contact is pushed by the lever to act, which is in an open state, while the moving contact is closed. The delay time of the relay is the time when the coil is energized until the delay contact completes its action. When the coil is powered off, the relay is restored by the recovery action of the spring.
