如何从字符串数组中的Ruby 2.0获得价值 [英] How get value from array of strings in Ruby 2.0

问题描述

我有这个字符串数组：

 数组= [耐克，耐克蒸，耐克多愁善感，耐克的实力，
          顺利潜伏，阿迪达斯空气，阿迪达斯jogar，阿迪达斯多愁善感，阿迪达斯高跟鞋]
 

我想从这个字符串中提取像查询SQL。

例如，如果用户输入单词耐克。然后4个字符串应该是回报结果

 耐克，耐克蒸，耐克多愁善感，耐克的实力
 

例如，如果用户输入单词阿迪达斯。然后4个字符串应该是回报结果

 阿迪达斯空气，阿迪达斯jogar，阿迪达斯多愁善感，阿迪达斯高跟鞋
 

这可能吗？

解决方案

  array.grep（查询）
 

返回与查询匹配的数组子集。

I have this array of strings:

array = [ "nike air", "nike steam","nike softy" ,"nike strength",
          "smooth sleeper","adidas air","addidas jogar","adidas softy","adidas heels"]

I want to extract strings from this as SQL like query.

E.g if user enter word "nike". Then 4 strings should be return as result

           "nike air", "nike steam","nike softy" ,"nike strength"

E.g if user enter word "adidas". Then 4 strings should be return as result

           "adidas air","addidas jogar","adidas softy","adidas heels"

Is it possible?

解决方案

array.grep(query)

Returns the array subset that matches the query.
