合并两个json格式基于

Question

我想合并json格式（优先使用下划线），但不知道它是如何完成的。第一个json没有要映射的_id指示符。

JSON 1：

{ 
    "0001": { 
     "answer": "sad" 
    }, 
    "0002": { 
     "answer": "sad1" 
    } 
} 

JSON 2：

合并后

[ 
    { 
     "_id": "0001", 
     "question": "who am I" 
    }, 
    { 
     "_id": "0002", 
     "question": "How old are you?" 
    } 
] 

最终结果：

[ 
    { 
     "_id": "0001", 
     "question": "who am I", 
     "answer": "sad" 
    }, 
    { 
     "_id": "0002", 
     "question": "How old are you?", 
     "answer": "sad1" 
    } 
] 

为方针，我试图改变JSON 1至以下格式第一但无法实现。

[ 
    { 
     "_id": "0001", 
     "answer": "sad" 
    }, 
    { 
     "_id": "0002", 
     "answer": "sad1" 
    } 
] 

Answer 1

好了，你可以做一个foreach添加新的答案元素：

var json1 = { 
    "0001": { 
     "answer": "sad" 
    }, 
    "0002": { 
     "answer": "sad1" 
    } 
}; 

var json2 = [ 
    { 
     "_id": "0001", 
     "question": "who am I" 
    }, 
    { 
     "_id": "0002", 
     "question": "How old are you?" 
    } 
]; 

json2.forEach(function(o) { 
    o.answer = json1[o._id].answer; 
}); 

console.log(json2);
