    js 怎么使用正则表达式-理解Javascript的正则表达式

    相信很多人第一次见到正则表达式的第一印象都是懵逼的,对新手而言一个正则表达式就是一串毫无意义的字符串,让人摸不着头脑。但正则表达式是个非常有用的特性,不管是、PHP、Java还是Python都有正则表达式。俨然正则表达式已经发展成了一门小语言。作为编程语言的一部分,它不想变量,函数,对象这种概念那么容易理解。很多人对于正则表达式的理解都是基于简单的匹配,等到业务中用到完全靠从网上copy来解决问题。不得不说,随着各种开源技术社区的发展,靠copy的确能解决业务中绝大多数的问题,但作为一名有追求的程序员,是绝对不会让自己仅仅依靠Ctrl C + Ctrl V来编程的。本文基于的正则表达式,结合笔者个人的思考和社区内一些优秀正则表达式文章来对正则表达式进行讲解。
