你可以试试这个:

"ab c d efg hi ".split.map(&:strip)

为了得到这个:

["ab, "c", "d", "efg", "hi"]

或者如果你想要一个字符串，只需使用:

"ab c d efg hi ".split.join

你可以试试这个

"Some Special Text Values".gsub(/[[:space:]]+/, "")

使用:space:删除不间断的空格和常规空格。

s = "I have white space".delete(' ')

并模拟PHP的trim()函数:

s = "   I have leading and trailing white space   ".strip

相关回答:

"   clean up my edges    ".strip

返回

"clean up my edges"

别忘了:

$ s = "   I have white space   ".split
=> ["I", "have", "white", "space"]

Ruby的.strip方法执行与trim()相当的PHP功能。

删除所有空白:

"  leading    trailing   ".squeeze(' ').strip
=> "leading trailing"

@塔斯让我意识到我原来的答案连续删除重复的字母-恶心!从那以后，我改用了压缩方法，如果使用Rails框架，这种方法对这种情况更聪明。

require 'active_support/all'
"  leading    trailing   ".squish
=> "leading trailing"

"  good    men   ".squish
=> "good men"
