Question

我有JSON数据，我试图以以下格式存储在2D数组中：

[2009-01,324, 1075, 940, 441, 1040, 898, 1343]
[2009-02 295, 958, 904, 434, 1038, 793, 1246 ]

上面的符号视觉表示道歉。我有JSON数据，我使用for循环来获取密钥及其值，但我不知道如何将其存储在二维数组中。我在概念上正在努力。我是初学者，真的想要一些指导。谢谢。

<script>
$.getJSON('data.json', function (data) {

var response = data;

var listOfTimes = new Array();
for(i = 0; i < 2; i++){ //number of rows...
 for(j = 0; j< 8; j++){ //number of columns

 for(key in response){
 ....not sure what to do here 
 }    
 } 
}

});
</script>

JSON数据采用以下格式：

"2009-01": {
    "bbcfour": 324,
    "bbcnews24": 1075,
    "bbcone": 940,
    "bbcthree": 441,
    "bbctwo": 1040,
    "cbbc": 898,
    "cbeebies": 1343
  },
  "2009-02": {
    "bbcfour": 295,
    "bbcnews24": 958,
    "bbcone": 904,
    "bbcthree": 434,
    "bbctwo": 1038,
    "cbbc": 793,
    "cbeebies": 1246
  }

Answer 1

尝试遍历所有日期＆amp;然后在他们的属性上内循环

<script>
    $.getJSON('data.json', function (data) {
        var arr = [];

        for(var date in data){
            var items = [];
            for(var key in date){
                items.push(date[key]);
            }   
            arr.push(items);
        }    

        console.log(arr); // the requested array
    });
</script>

Answer 2

var response = data;

var listOfTimes = new Array();
for(i = 0; i < 2; i++){ //number of rows...
 listOfTimes[i]=response[i];
 for(j = 0; j< 8; j++){ //number of columns
 listOfTimes[i]=repsonse[i][j];   
 } 
}

我认为你正在寻找这个，它将根据你的地图创建一个数组数组。不确定为什么不能使用数组数据模型。（注意那个$ .each，它需要jQuery）

var resp =  {"2009-01": {
    "bbcfour": 324,
    "bbcnews24": 1075,
    "bbcone": 940,
    "bbcthree": 441,
    "bbctwo": 1040,
    "cbbc": 898,
    "cbeebies": 1343
  },
  "2009-02": {
    "bbcfour": 295,
    "bbcnews24": 958,
    "bbcone": 904,
    "bbcthree": 434,
    "bbctwo": 1038,
    "cbbc": 793,
    "cbeebies": 1246
  }};

var arrays = [];
for (mainKey in resp) { 
  var array = []; 
  arrays.push(array);  
  array.push(mainKey); 
  $.each(resp[mainKey], function(key, value) { 
    array.push(value) 
  }); 
};

jsfiddle demo

var mainobj={
  "2009-01": {
    "bbcfour": 324,
    "bbcnews24": 1075,
    "bbcone": 940,
    "bbcthree": 441,
    "bbctwo": 1040,
    "cbbc": 898,
    "cbeebies": 1343
  },
  "2009-02": {
    "bbcfour": 295,
    "bbcnews24": 958,
    "bbcone": 904,
    "bbcthree": 434,
    "bbctwo": 1038,
    "cbbc": 793,
    "cbeebies": 1246
  }
};

var my2darray=[];

for (var date in mainobj) {
   var temparray=[date];
    for(val in mainobj[date]){
        temparray.push(mainobj[date][val]);
    }
   my2darray.push(temparray);
}
console.log(my2darray);

输出：

[["2009-01", 324, 1075, 940, 441, 1040, 898, 1343],
["2009-02", 295, 958, 904, 434, 1038, 793, 1246 ]]
