合并两个数组一起

Question

我有这两个数组

Hotel = 'hilton', 'marriot' 
Price = '$350', '$375' 

我怎么会去两个数组合并在一起，使得价格一键酒店。

所以，当我访问

Price[0] 

它输出

'$350' => 'hilton' (or however the correct output should be) 

Answer 1

做如下使用Array#zip和Hash::[]：

Hotel = 'hilton', 'marriot' 
Price = '$350', '$375' 
Hash[Price.zip(Hotel)] 
# => {"$350"=>"hilton", "$375"=>"marriot"} 

但为了满足您的发布说明：

Hotel = 'hilton', 'marriot' 
Price = '$350', '$375' 
array_of_hash = Price.each_index.map { |i| { Price[i] => Hotel[i]} } 
# => [{"$350"=>"hilton"}, {"$375"=>"marriot"}] 
array_of_hash[0] # => {"$350"=>"hilton"} 

现在选择，无论哪种方式适合您的需要。
