javascript - 将一个javascript嵌套对象数据结构转换为嵌套数组

Question

我正在尝试将 JSON 字符串转换为 Javascript 对象字面量。我认为有一些循环是可能的，但我无法完成它。目标结构如下所示，“chartData”。

fiddle 可以在这里找到:http://jsbin.com/ajemih/13/edit

这是 JSON 数据:

{
   "1b":{
      "allLoad":"130",
      "loadMovement":"111",
      "allMovement":"111"
   },
   "1a":{
      "allLoad":"910",
      "loadMovement":"671",
      "allMovement":"280"
   },
   "systemLoad":"963"
}

转换后应该是这样的:

chartData = [[['loadMovement', 111], 
              ['allMovement', 120], 
              ['allLoad', 130]], 
             [['Load+Move', 671], 
              ['allMovement', 280], 
              ['allLoad', 910]]];

我认为这可行:

工作演示:http://jsfiddle.net/jfriend00/YmjDR/

var data = {
   "1b":{
      "allLoad":"130",
      "loadMovement":"111",
      "allMovement":"111"
   },
   "1a":{
      "allLoad":"910",
      "loadMovement":"671",
      "allMovement":"280"
   },
   "systemLoad":"963"
};

var chartData = [];

for (var i in data) {
    var item = data[i];
    var outer = [];
    // skip over items in the outer object that aren't nested objects themselves
    if (typeof item === "object") {
        for (var j in item) {
            var temp = [];
            temp.push(j);
            temp.push(item[j]);
            outer.push(temp);
        }
    }
    if (outer.length) {
        chartData.push(outer);
    }
}
