jquery - 如何将 '{"key1" => "value1", "key2" => "value2"}' 转换为 '{key1:"value1", key2: "value2"}'

Question

我想从以下转换：

{"key1" => "value1","key2" => "value2"}

至

{key1: "value1", key2: "value2"}

Answer 1

目前，您必须这样做：

{"key1" => "value1", "key2" => "value2"}
.map{|k, v| [k.to_sym, v]}.to_h
# => {:key1=>"value1", :key2=>"value2"}

稍微更有效的是：

{"key1" => "value1", "key2" => "value2"}
.each_with_object({}){|(k, v), h| h[k.to_sym] = v}
# => {:key1=>"value1", :key2=>"value2"}

在不久的将来，Hash#transform_keys可能会变得可用。
