^从行开始处匹配，$从行结束处开始匹配。A从字符串开始处匹配，Z从字符串结束处匹配。例如：("thisisnthetime",/^the/)=>thisisn<<the>>time("thisisnthetime",/is$/)=>this<<is>>nthetime("thisisnthetime",/Athis/)=><<this>>isnthetime("thisisnthetime",/Athe/)=>nomatch("thisisnthetime",/timeZ/)=>thisisnthe<<time>>("thisisnthetime",/timez/)=>thisisnthe<<time>>("thisisnthetime",/isZ/)=>nomatch("thisisnthetime",/isz/)=>nomatch
