如何使用 Javascript 将 JSON 格式转换为另一种格式？

Question

我正在使用 Oracle JET.The 实现日期选择器 JET.The JET cookbook 为我提供了具有 JSON 文件的示例数据选择器，如下所示。

 "Holidays": {
  "*": {
     "1": {
        "14": {
           "className": "holiday"

        },
        "26": {
           "className": "holiday"

        }
     }
   }

而 Json 我从休息服务中获得的文件如下

 [
 {
     "YEAR":"2017",
     "MONTH":"1",
     "DAY":[
     {
         "N_DAYS":"25",
         "className":"holiday"
     },
     {
         "N_DAYS":"25",
         "className":"holiday"
     }
 ]

      },
  ];

我如何转换 JSON 我从其他服务获得的文件，如 JET cookbook

中提供的上述服务

Answer 1

myStuff = [
  {
     "YEAR":"2017",
     "MONTH":"1",
     "DAY":[
       {
           "N_DAYS":"14",
           "className":"holiday"
       },
       {
           "N_DAYS":"26",
           "className":"holiday"
       }
    ]
  },
];

Holidays = {
  '*': { }
}

for (var i = 0; i < myStuff.length; i++) {
  var month = myStuff[i].MONTH;
  for (var j = 0; j < myStuff[i].DAY.length; j++) {
    if (typeof Holidays['*'][myStuff[i].MONTH] == 'undefined') {
      Holidays['*'][month] = {};
    }
    
    Holidays['*'][myStuff[i].MONTH][myStuff[i].DAY[j].N_DAYS] = {
      className: myStuff[i].DAY[j].className
    }
  }
}

Holidays = { Holidays: Holidays }
console.log(Holidays);

这是 fiddle link https://fiddle.jshell.net/q80212b7/1/

   var myStuff= [ {
    "YYYY_YEAR" : "2013",
    "MMM_MONTH" : "06",
    "DAY_OUT" : {
      "DAY_OUT_ITEM" : {
        "N_DAYS" : "06",
        "CLASSNAME" : "Holiday",
        "TOOLTIP" : "Lalat Al Miraj"
      }
    }
  }, {
    "YYYY_YEAR" : "2017",
    "MMM_MONTH" : "06",
    "DAY_OUT" : {
      "DAY_OUT_ITEM" : [ {
        "N_DAYS" : "06",
        "CLASSNAME" : "Holiday",
        "TOOLTIP" : "Lalat Al Miraj"
      } ]
    }
  }, {
    "YYYY_YEAR" : "2013",
    "MMM_MONTH" : "01",
    "DAY_OUT" : {
      "DAY_OUT_ITEM" : [ {
        "N_DAYS" : "01",
        "CLASSNAME" : "Holiday",
        "TOOLTIP" : "New Year's Day"
      }, {
        "N_DAYS" : "24",
        "CLASSNAME" : "Holiday",
        "TOOLTIP" : "Milad Un Nabi"
      } ]
    }
  }, {
    "YYYY_YEAR" : "2017",
    "MMM_MONTH" : "01",
    "DAY_OUT" : {
      "DAY_OUT_ITEM" : [ {
        "N_DAYS" : "01",
        "CLASSNAME" : "Holiday",
        "TOOLTIP" : "New Year's Day"
      }, {
        "N_DAYS" : "24",
        "CLASSNAME" : "Holiday",
        "TOOLTIP" : "Milad Un Nabi"
      } ]
    }
  }];

   

Holidays = {
   'value': { }
}


 for (var i = 0; i < myStuff.length; i++) {
  var year = parseInt(myStuff[i].YYYY_YEAR,10);

 
 var month = parseInt(myStuff[i].MMM_MONTH,10);
  
  
 if (typeof Holidays['value'][myStuff[i].YYYY_YEAR] == 'undefined') {
  Holidays['value'][year] = {};
}
  if (typeof Holidays['value'][year][myStuff[i].MMM_MONTH] == 'undefined') {
  Holidays['value'][year][month] = {};

}
 if(myStuff[i].DAY_OUT.DAY_OUT_ITEM instanceof Array) {

 for (var j = 0; j < myStuff[i].DAY_OUT.DAY_OUT_ITEM.length; j++) {
 
  var day=parseInt(myStuff[i].DAY_OUT.DAY_OUT_ITEM[j].N_DAYS,10);
 Holidays['value'][year][month][day] = {
  className: myStuff[i].DAY_OUT.DAY_OUT_ITEM[j].CLASSNAME,
   tooltip: myStuff[i].DAY_OUT.DAY_OUT_ITEM[j].TOOLTIP
  };
  }
  }
  else
   {
 
  var day=parseInt(myStuff[i].DAY_OUT.DAY_OUT_ITEM.N_DAYS,10);
 Holidays['value'][year][month][day] = {
  className: myStuff[i].DAY_OUT.DAY_OUT_ITEM.CLASSNAME,
   tooltip: myStuff[i].DAY_OUT.DAY_OUT_ITEM.TOOLTIP
   };

  }
}



 Holidays = { Holidays: Holidays }
 console.log(JSON.stringify(Holidays.Holidays));
