紅寶石從字典中的基於關閉的關鍵

Question

我有類似的數據存儲到這個數組的數組中刪除的項鍵入字典。 即如果我想刪除名稱爲「Bill」的字典，我該如何去做呢？

Answer 1

people.delete_if{|element| element['name'] == 'Bill'} 
# => [{"name"=>"Jim", "car"=>"Porche", "houseSize"=>"big"}] 

順便說一句：你的哈希值缺少一些逗號。

people = [ 
    { 
    'name' => "Jim", 
    'car' => "Porche", 
    'houseSize' => "big" 
    }, 
    { 
    'name' => "Bill", 
    'car' => "Honda", 
    'houseSize' => "small" 
    } 
]
