javascript - 如何使用嵌套 json 中的键制作另一个嵌套 json

Question

来自源的字符串来自 JSON 对象中的碎片化 JSON 对象。我想将此 JSON 结构转换为另一个简单的 JSON 结构:

{  
  "nestA":{  
    "a":"link",
    "b":2711
  },
  "nestB":{  
    "a":"img",
    "b":4165 
  }
}

能不能改成这样

 {  
     "key":"nestA"
     "a":"link"
     "b":711
 },
 {  
     "key":"nestB"
     "a":"img"
     "b":165
 }

Answer 1

//convert json string into an object
var json = '{"nestA":{"a":"link","b":2711},"nestB":{"a":"img","b":4165}}'
var sourceObject = JSON.parse(json);

//get a list of the object keys
var keys = Object.keys(sourceObject);

//create a new array to hold our output
var array = [];

//loop through our keys adding them to our array in the format we want
keys.forEach(function(key){
	var nest = sourceObject[key];
	nest.key = key;
	array.push(nest);
});

//convert our array back to json
var result = JSON.stringify(array);
console.log(result);
