Ruby从数组中选择字符串(Ruby select string from array)

Ruby从数组中选择字符串(Ruby select string from array)

我基本上试图选择匹配特定字符串的数组中的每个字符串。

我目前正在使用以下代码，但正如大家所知，这只提供了一系列评估为true的元素的索引。 我想要那个位置的实际字符串。

arr.each_index.select{|i| arr[i].chars.sort.join == someString}

I am basically trying to select every string in an array that matches a particular string.

I am currently using the following code, but as you guys know, this only gives an array of the indexes of the elements that evaluate to true. I want the actual string at that position.

arr.each_index.select{|i| arr[i].chars.sort.join == someString}

最满意答案

尝试这个：

arr.select { |s| s == "some string" }

一个例子：

arr = %w(One Two Three Two Two) arr.select { |x| x == "Two" } => ["Two", "Two", "Two"]

Try this:

arr.select { |s| s == "some string" }

An example:

arr = %w(One Two Three Two Two) arr.select { |x| x == "Two" } => ["Two", "Two", "Two"]
