Question

我有如下JSON对象，我试图通过第一组键对该对象进行分组和推送。

main =  {"answer_options":{
            "1":{"1":"optical projection<\/p>\r\n","2":"optical mechanism projection<\/p>\r\n","3":"mechanical projection<\/p>\r\n","4":"all the above<\/p>\r\n"},
            "2":{"5":"Greenwich to the place<\/p>\r\n","6":"equator to the poles<\/p>\r\n","7":"equator to the nearer pole<\/p>\r\n","8":"equator to the nearer pole along the meridian of the place<\/p>\r\n","9":"none of these.<\/p>\r\n"}},
    "question":
            {"1":"The stereo plotting instruments are generally manufactured on the principle of<\/p>\r\n","2":"Latitude of a place is the angular distance from<\/p>\r\n"}
    };

我试图获得如下输出..任何人都可以帮忙。

{"1" : 
        {{"1" : "The stereo plotting instruments are generally manufactured on the principle of<\/p>\r\n"},
        {"1":"optical projection<\/p>\r\n","2":"optical mechanism projection<\/p>\r\n","3":"mechanical projection<\/p>\r\n","4":"all the above<\/p>\r\n"}}, 
    {"2": 
        {{"2" : "Latitude of a place is the angular distance from<\/p>\r\n"},
        {"5":"Greenwich to the place<\/p>\r\n","6":"equator to the poles<\/p>\r\n","7":"equator to the nearer pole<\/p>\r\n","8":"equator to the nearer pole along the meridian of the place<\/p>\r\n","9":"none of these.<\/p>\r\n"}}
    }

您的预期结果不是一个明智的（或常用的）格式。这是替代方法。您可以使用for / in来循环问题，并将其与相应的答案选项相匹配。

main = {
  "answer_options": {
    "1": {
      "1": "optical projection<\/p>\r\n",
      "2": "optical mechanism projection<\/p>\r\n",
      "3": "mechanical projection<\/p>\r\n",
      "4": "all the above<\/p>\r\n"
    },
    "2": {
      "5": "Greenwich to the place<\/p>\r\n",
      "6": "equator to the poles<\/p>\r\n",
      "7": "equator to the nearer pole<\/p>\r\n",
      "8": "equator to the nearer pole along the meridian of the place<\/p>\r\n",
      "9": "none of these.<\/p>\r\n"
    }
  },
  "question": {
    "1": "The stereo plotting instruments are generally manufactured on the principle of<\/p>\r\n",
    "2": "Latitude of a place is the angular distance from<\/p>\r\n"
  }
};

var newMain = {};
for (var key in main.question) {
  newMain[ key ] = [
      main.question[key],
      main.answer_options[key]
    ];
}

console.log(newMain);
