我有一个字符串,如“这是一个测试”.我想用空格字符分割字符串.我这样做：
puts " This is a test ".strip.each(' ') {|s| puts s.strip}
结果是：
This
is
a
test
This is a test
为什么最后一行“这是一个测试”？
而我需要的是,如果两个字之间有两个或更多的空格字符,那就不应该返回一个“行”.
我只想得到一个给定的字符串分割的单词.
有没有人有想法？
解决方法
irb(main):002:0> " This is a test ".split => ["This","is","a","test"] irb(main):016:0* puts " This is a test ".split This is a test
str.split(pattern=$;,[limit]) => anArray
If pattern is omitted,the value of $; is used. If $; is nil (which is the default),str is split on whitespace as if ` ’ were specified.
