在Ruby哈希中查找特定值

Question

我正在尝试访问以下哈希中的"click_me_123"，但我无法解决。我尝试过使用['actions']['text']['value']和[:actions][:text][:value]，但我检索到了适当的值。渴望理解我做错了什么。

Answer 1

actions是一个数组，因此您需要访问特定索引或循环访问它。

例如，如果您的散列名为hsh:

hsh.dig('actions', 0, 'value')

这是编写hsh['actions'][0]['value']的另一种方法，但如果任何元素为零，则会正常失败。

或者。。。

hsh['actions'].map { |action| action['value'] }

返回['click_me_123']
