西南边陲，贩毒活动猖獗，毒枭阮霞、萧金、托姆等头目只手遮天，为了打通三棵树经昆明到香港的通道，并盗取生物学家陈百涛教授的最新技术资料，阮霞、萧金、托姆派遣李新潜回大陆，李新回境后，假意与陈教授之女陈思思发生关系，在潜入陈教授书房被发现后，再次安排同伙榴红以保姆身份进入陈教授家中。而李新在窃取资料后，意想不到招来除警方压力的黑帮连环追杀…… 以刑警队长高一朗为首，警员杨辉、傣族战士岩松、训犬主…更近一些，戚继光更慌了。秋香偷入柴房，两人开始互表心意。这事结果如何，完全跟咱们不相干，都是她自己作出来的。郑氏见她居然笑了，心中顿时苦涩不已。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 ~
