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 ~本片讲的是父母双亡与爷爷相依为命的农村孩子石头，几经曲折被浙江温州平阳武校破格招收免费学习，在女老师肖教练的精心培养下，最终为学校赢得武术大赛冠军的感人故事。飞影用其独特的速度省出了许多的时间，此时此刻，这些许的时间就显得是那么的重要。MDT should record and summarize cases with significant differences in pathological, radiological and clinical conditions.Leave a message and take up a place ~刻骨相思，苦苦等待，千里寻觅……只要能换一句愿随姐姐浪迹天涯，也就足够了。警官德夫正在调查一宗双重谋杀案，只有两名证人，他们也是主要嫌疑人。嫌疑犯之一，著名的作家；另一个，是年轻的家庭主妇玛雅。不同的故事，却在同一个命运之夜联系到了一起，而背后的真相也远非表面这么简单……这是一部没有歌舞也没有外挂的印度电影，只有悬疑和逻辑推理。
