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 ~一组年轻人重回到工作过的夏令营营地，意图掩盖五年前的一场意外。随着他们的到来，营地每天都有人意外死亡，究竟五年前发生了什么，谁又是凶手。本·阿弗莱克、奥斯卡·伊萨克、查理·汉纳姆、加内特·赫德兰、佩德罗·帕斯卡和亚德里亚·霍纳主演《三方国界》，J·C·尚多尔将用他在马克·鲍尔的基础上重写过的剧本执导。讲述五个朋友为扳倒一个大毒枭而再度联合起来，结果却导致一系列意想不到的后果。“三方国界”是指巴拉圭、阿根廷和巴西之间臭名昭著的边界地带，伊瓜苏河和巴拉那河在这里交汇，使这片区域难以监控，成为了有组织犯罪的庇护所。道光年间，河北玉田县有一位年青人杨昱乾自幼喜爱习武。而且他的机智仁勇，也为村中人所赞赏。乾出外寻找名师学艺落泊京城之际，有幸遇上一八卦掌的真英雄董汉成，欲上前拜师，却因董另有要事在身而赶速离去令乾失望不已。乾经过几番波折、转辗到河南甘县陈家堡，欲拜太极高手村长陈正英为师，却被英一口拒绝，并将乾赶出村。英遭人下毒，乾在令英不失尊严的情况下，救英一命，英深受感动，破例正式收乾为徒。乾终能如愿以偿，武功进步神速。在荣亲王王府里的武术大赛中，乾以其出神入化的太极拳，战胜八大高手，声名大噪。在英的指点下，乾那套改良的太极更为完善。乾在京城设馆授徒，不管清人、汉人或外国人，甚至残疾人士，均倾囊而授，绝无半点隐藏，令太极得以发扬光大，传向世界每一角落。乾更将孝、悌、忠、信、仁、义、礼、智，这些中国人传统的美德发挥得淋漓尽致，令乾成为“杨家太极”一代宗师。Six fairies
