Javascript 使用JS解析Json中的嵌套对象

我有一个Json格式：

{"year":{"month1":{"date1":{"device1":{"users":6}}}}

样本：

{"2013":{"2":{"5":{"GT-N7000":{"users":1}},"6":{"GT-N7000":{"users":9},"HTC Sensation Z710a":{"users":1}},"7":{"GT-N7000":{"users":15},"HTC Sensation Z710a":{"users":2},"M903":{"users":1}}}}}

如何从Json生成新的用户数组。例如：

GT-N7000 = [1, 9, 15]
M903 = [1]

我尝试了嵌套

for

循环，也尝试了

for..in

循环。我肯定我犯了一个错误。您知道如何过滤/解析此类嵌套json对象所需的信息吗？

大多数现代浏览器都支持原生json.parse方法。有关详细信息，请参见此问题

我想您会这样做：

var json = {"2013":{"2":{"5":{"GT-N7000":{"users":1}},"6":{"GT-N7000":{"users":9},"HTC Sensation Z710a":{"users":1}},"7":{"GT-N7000":{"users":15},"HTC Sensation Z710a":{"users":2},"M903":{"users":1}}}}}; 

var result = {}, year, month, date, item;
for (year in json) {
  for(month in json[year]) {
    for(date in json[year][month]) {
       for(item in json[year][month][date]) {
          if(item in result) {
              result[item].push(json[year][month][date][item].users)  // this bit might need editing?
          } else {
              result[item] = [json[year][month][date][item].users] // this be also might need editing
          }
       }
    }
  }
}

我可以想象你会这样做：

var json = {"2013":{"2":{"5":{"GT-N7000":{"users":1}},"6":{"GT-N7000":{"users":9},"HTC Sensation Z710a":{"users":1}},"7":{"GT-N7000":{"users":15},"HTC Sensation Z710a":{"users":2},"M903":{"users":1}}}}}; 

var result = {}, year, month, date, item;
for (year in json) {
  for(month in json[year]) {
    for(date in json[year][month]) {
       for(item in json[year][month][date]) {
          if(item in result) {
              result[item].push(json[year][month][date][item].users)  // this bit might need editing?
          } else {
              result[item] = [json[year][month][date][item].users] // this be also might need editing
          }
       }
    }
  }
}
