Question

我对这个json /数组很新，下面的数据来自一个表，我需要将它移植到另一个表，这需要我根据id最高的国家进行排序... 装载的国家是动态的...... 感谢有人能告诉我如何将所有国家分组到＃34;国家＆＃34;并推送到正确的数据[i]

var data = [
        {"Product": "DESKTOP", "Type": "APPLE" , "CN": "", "IN": "", "SG": "20"},
        {"Product": "DESKTOP", "Type": "DELL" , "CN": "", "IN": "", "SG": "20"},
        {"Product": "LAPTOP", "Type": "XXX", "CN": "", "IN": "90", "SG": "28"},
        {"Product": "MOBILE", "Type": "XXX","CN": "1","IN": "","SG": "28"},
        {"Product": "TABLET", "Type": "XXX","CN": "13","IN": "","SG": "238"}
    ]

what_i_need = [
    {"Product": "DESKTOP",
     "Type": "APPLE",
     "Country": [
        {"country": "CN", "id": ""}
        {"country": "IN", "id": ""}
        {"country": "SG", "id": "20"}
    ]},
    ...
    ...
]

我试着做循环，但结果就像这样

[{"country": "CN", "id": ""}
{"country": "IN", "id": ""}
{"country": "SG", "id": "20"}
{"country": "CN", "id": ""}
{"country": "IN", "id": ""}
{"country": "SG", "id": "20"}

您可以使用map功能更改数组格式。

＆＃13;

var data = [{
    "Product": "DESKTOP",
    "Type": "APPLE",
    "CN": "",
    "IN": "",
    "SG": "20"
  },
  {
    "Product": "DESKTOP",
    "Type": "DELL",
    "CN": "",
    "IN": "",
    "SG": "20"
  },
  {
    "Product": "LAPTOP",
    "Type": "XXX",
    "CN": "",
    "IN": "90",
    "SG": "28"
  },
  {
    "Product": "MOBILE",
    "Type": "XXX",
    "CN": "1",
    "IN": "",
    "SG": "28"
  },
  {
    "Product": "TABLET",
    "Type": "XXX",
    "CN": "13",
    "IN": "",
    "SG": "238"
  }
];

var fixedKeys = ["Product", "Type"];
var result = data.map(function(item) {
  var x = {
    Product: item.Product,
    Type: item.Type,
    Country: []
  };
  for (var country in item) {
    if (item.hasOwnProperty(country) && !fixedKeys.includes(country))
      x.Country.push({
        country: country,
        id: item[country]
      });
  }
  return x;
});

console.log(result);

您可以使用解决方案https://jsfiddle.net/sdhaojsp/

var data = [
        {"Product": "DESKTOP", "Type": "APPLE" , "CN": "", "IN": "", "SG": "20"},
        {"Product": "DESKTOP", "Type": "DELL" , "CN": "", "IN": "", "SG": "20"},
        {"Product": "LAPTOP", "Type": "XXX", "CN": "", "IN": "90", "SG": "28"},
        {"Product": "MOBILE", "Type": "XXX","CN": "1","IN": "","SG": "28"},
        {"Product": "TABLET", "Type": "XXX","CN": "13","IN": "","SG": "238"}
    ];
  var outputData = [];  
$.each(data, function(i){
	var temp = {};
  var tempCountry = {};
	$.each(data[i], function(key){
  	if(key === "Product" || key === "Type"){
    	temp[key] = data[i][key];
    }else{
    	tempCountry["country"] = key;
      tempCountry["id"] = data[i][key];
      if(typeof temp["Country"] === 'undefined') {
      	temp["Country"] = [];
      }
      	temp["Country"].push(tempCountry);
        tempCountry = {};
    }
  });
  outputData.push(temp);
});

console.log(outputData);
