Question

这很简单。我有这个：

[{"key":"jim","values":{"count":2,"total":79}},
 {"key":"carl","values":{"count":1,"total":120}},
 {"key":"stacy","values":{"count":3,"total":90}}]

我希望如此：

[{ "key": 'jim', count: 2, total: 79 },
  { "key": 'carl', count: 1, total: 120},
  { "key": 'stacy', count:3, total: 90}];

我已经阅读了有关嵌套对象的内容，以及使用Javascript进行的其他类型的数据操作，但我无法解决我的问题。我想我需要使用.map方法，但我不能使它工作。感谢。

试试这个伙伴吧！正如你所说，你是初学者，我做了一步一步的基本循环，请完成代码。此代码适用于动态一级嵌套对象。

var arr = [{"key":"jim","values":{"count":2,"total":79}},
     {"key":"carl","values":{"count":1,"total":120}},
     {"key":"stacy","values":{"count":3,"total":90}}]

var newArr = [];
for (var i = 0; i < arr.length; i++)  {
   var currentObj = arr[i];
   var Obj = {};  // Temporary object
   for (var key in currentObj) {
      if (typeof currentObj[key] === 'object') {  // If it is nested object
        for (var deepkey in currentObj[key]) {    // Loop again
          Obj[deepkey] = currentObj[key][deepkey];
        }
      }
    else {
      Obj[key] = currentObj[key];  
    }
  }
  newArr.push(Obj);
 }

console.log(newArr); // [{ "key": 'jim', count: 2, total: 79 },
                         { "key": 'carl', count: 1, total: 120},
                         { "key": 'stacy', count:3, total: 90}];

将适用于不同的输入

var arr = [{"key":"jim", "hey": {"ting": "bing"} ,"values": {"count":2,"total":79}},
 {"key":"carl","values":{"count":1,"total":120}},
  {"key":"stacy","values":{"count":3,"total":90}}]

使用for循环创建一个具有所需格式的新数组。

var initial = [{"key":"jim","values":{"count":2,"total":79}},
{"key":"carl","values":{"count":1,"total":120}},
{"key":"stacy","values":{"count":3,"total":90}}];

var target =  [];
var obj = {};
for(var i = 0; i< initial.length; i++) {
   obj = {"key": initial[i].key, count: initial[i].values.count, total: initial[i].values.total};
   target.push(obj);
  }

console.log(target);

确定。我终于找到了一些对我来说更简单的东西：
