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 ~1990年代，上海某所高校。来自偏远小城的杨铮（李亚鹏饰）自小好强，大学里亦不例外。他结识不同专业但同爱流汗的乐言（王学兵饰）、雨森（廖凡饰）、佳伟（崔达治饰）和若彤（王渝文饰）后，四个男生组成了一支男子接力赛跑队伍，若彤做了拉拉队的队长。随后如天使的女孩文慧（徐静蕾饰）走进杨铮的生活，成为他生命中最重要的人，他不知文慧是雨森暗恋长达一年的女孩，也不知若彤一直对他倾心，而乐言又偷偷爱着若彤，但这些没有影响他们的友情，几个年轻人在操场上度过了许许多多的欢乐时光。激情褪去，杨铮与文慧的爱情遭遇生活。杨铮要毕业时，文慧与他就工作问题发生激烈的争吵，两人分手，杨铮去了南方做生意，伤心的文慧开始与雨森交往。雨森察觉到杨铮依旧在文慧心中占有很重的分量时，动情向她表白，却不幸死于车祸，杨铮返校与大伙一起以跑接力的方式将他怀念，并借机对文慧重新展开追求，文慧无法接受。不久文慧之外的所有人毕业离校，若彤进了电视台做记者，乐言成了设计师，杨铮则又回南方。一年过去，始终放不下文慧的杨铮再返校园，却得知文慧即将Earlier this year, a blackmail software called "WannaCry" began to attack the Internet, from Chinese universities to British hospitals. In April this year, IDT, a Newark, New Jersey-based telecommunications company, suffered a similar attack, which was discovered by Goran Ben-Oni, the company's global chief operating officer. As Ben Oni said in an interview with the New York Times, he immediately realized that this blackmail software attack is different from other attacks against companies.
