For example, if we want to implement a JS function, Such as form validation, Then if we don't use the policy pattern in javascript described in the previous chapter to solve the form validation encapsulation code, It is a temporary form validation function written by itself. Certainly without any encapsulation, Then at this time, we will pop up a prompt to the user for whether the two values are equal. If there is a form verification on another page, their judgment method and business logic are basically the same, but the comparison parameters are different. Should we consider writing a form verification code again? So now we can consider using the template method pattern to solve this problem. Common methods are extracted, and different methods are implemented by specific subclasses. This design code also has the advantages of stronger scalability and better code ~近百天的海上漂泊对于杨长帆在内的绝大多数船员都是第一次，思乡与恐怖渐渐被麻木与平稳所冲淡，巨型船舶丰富的补给储备让舰队可以支持一年以上的航行，一些船只内甚至配置有饲养室，让船员们可以偶尔吃到新鲜的肉食。就算流尽最后一滴血，坚决将日寇歼灭在大南山脚下……巨炮轰鸣，摧枯拉朽敌寇心惊胆破，猛虎下山，横扫千军英雄方显本色。抗日战争进行到相持阶段，在南方柏城大南山，敌我双方进行着激烈的拉锯战，大南山防线犬牙交错，日军动用了飞机、大炮、坦克进入胶着阶段。日军久攻不下，为尽快打通南大门，敌酋中岛正雄精心策划了一场间谍战，组织了一个“蝴蝶小分队”潜入柏城，隐藏暗处秣马厉兵，企图从内部瓦解大南山的防线。我守军二十师抗日名将戴冲宇将军是敌人行动的主要目标，我共产党地下组织接获信息，立即派遣情报人员岳中民冒充军队特派员前往柏城，利用军统的身份，接管了柏城、荔城两地的军统组织，与日军的蝴蝶小分队、重庆军统三方展开一场斗智斗勇的生死较量，保证了我新四军与二十师在大南山与日寇的决战顺利进行，击溃了日军的蝴蝶行动组，粉碎了敌人大部队开往南方的美梦。影片为《侏罗纪世界》系列的完结篇，讲述了自从恐龙进入了人类世界，侏罗纪公园已经不复存在的故事。混乱只是暂时的，当荣郡王和世子率领三千龙禁卫围住慈宁宫，将永平帝和太后等人逼入最后一层宫内，这场叛乱幕后主使终于浮出水面。还说，你姑姑一家，还有你们，离开家里这么些年，肯定想吃家乡的东西，肯定吃不惯京城的菜，就又买了许多干笋干菜腊味什么的，连鸡鸭都逮了许多，拖了十几辆马车。
