javascript - 通过将所有日期转换为 ISOString 格式，将 Javascript 数组格式化为 JSON

Question

我有 javascript 对象数组，其中包含键和值。我的数组中有很多日期，我想将整个数组转换为正确的 JSON，在此过程中我还将数组内的所有日期转换为 ISOString 格式。我只能使用 JQuery、UnderscoreJS 或 momentz 库。

我的 javascript 数组的初始格式:

{  
   "primaryPerformerId":"122418",
   "primaryGroupingId":"63913",
   "primaryCategoryId":"1",
   "name":"Test Concert Event",
   "venueId":"82",
   "placeConfigs":[  
      {  
         "placeConfigId":"1232392"
      }
   ],
   "defaultLocale":"en_US",
   "metas":[  
      {  
         "templateId":"201",
         "name":"Test Concert Event",
         "locale":"en_US"
      }
   ],
   "unknownEventDateIndicator":"false",
   "unknownEventTimeIndicator":"false",
   "eventStartTime":"05/18/2016 08:04 PM",
   "trueOnSaleDate":"05/18/2016 08:04 PM",
   "firstPresaleDate":null,
   "status":"active",
   "dynamicAttributes":[  

   ],
   "lastChanceDate":"05/18/2016 08:04 PM",
   "onSaleDate":"05/15/2016 08:04 PM",
   "confirmDate":"05/16/2016 08:04 PM",
   "earliestPossibleInhandDate":"05/16/2016 08:04 PM",
   "latestPossibleInhandDate":"05/18/2016 08:04 PM"
}

预期格式:

{  
   "primaryPerformerId":"122418",
   "primaryGroupingId":"63913",
   "primaryCategoryId":"1",
   "name":"Test Concert Event",
   "venueId":"82",
   "placeConfigs":[  
      {  
         "placeConfigId":"1232392"
      }
   ],
   "defaultLocale":"en_US",
   "metas":[  
      {  
         "templateId":"201",
         "name":"Test Concert Event",
         "locale":"en_US"
      }
   ],
   "unknownEventDateIndicator":"false",
   "unknownEventTimeIndicator":"false",
   "eventStartTime":"2016-05-18T20:04:00.000Z",
   "trueOnSaleDate":"2016-05-17T20:03:00.000Z",
   "firstPresaleDate":null,
   "status":"active",
   "dynamicAttributes":[  

   ],
   "lastChanceDate":"2016-05-18T20:04:00.000Z",
   "onSaleDate":"2016-05-12T23:38:18.775Z",
   "confirmDate":"2016-05-11T23:38:18.775Z",
   "earliestPossibleInhandDate":"2016-05-10T20:04:00.000Z",
   "latestPossibleInhandDate":"2016-05-11T20:04:00.000Z"
}

这应该可以。它使用正则表达式查找日期值，并使用自定义处理程序将其组合在一起。我还想指出，这会将时区计算为该脚本运行的任何系统时区。由于输出时间采用 UTC 格式，您可能需要事先确保时区正确。

var o = {  
   "primaryPerformerId":"122418",
   "primaryGroupingId":"63913",
   "primaryCategoryId":"1",
   "name":"Test Concert Event",
   "venueId":"82",
   "placeConfigs":[  
      {  
         "placeConfigId":"1232392"
      }
   ],
   "defaultLocale":"en_US",
   "metas":[  
      {  
         "templateId":"201",
         "name":"Test Concert Event",
         "locale":"en_US"
      }
   ],
   "unknownEventDateIndicator":"false",
   "unknownEventTimeIndicator":"false",
   "eventStartTime":"05/18/2016 08:04 PM",
   "trueOnSaleDate":"05/18/2016 08:04 PM",
   "firstPresaleDate":null,
   "status":"active",
   "dynamicAttributes":[  

   ],
   "lastChanceDate":"05/18/2016 08:04 PM",
   "onSaleDate":"05/15/2016 08:04 PM",
   "confirmDate":"05/16/2016 08:04 PM",
   "earliestPossibleInhandDate":"05/16/2016 08:04 PM",
   "latestPossibleInhandDate":"05/18/2016 20:04"
};

document.body.innerText = JSON.stringify(o, function(key, value) {
    var res;
    if(res = /^\s*([0-9]{1,2})\s*\/\s*([0-9]{1,2})\s*\/\s*([0-9]{1,4})\s+([0-9]{1,2})\s*\:\s*([0-9]{1,2})(?:\s*(AM|PM))?\s*$/i.exec(value)) {
        value = (o.defaultLocale === 'en_US' ?
            new Date(res[3], res[1]-1, res[2], res[6] ? (res[6].toUpperCase() === 'PM' ? 12 : 0) + (res[4] === '12' ? 0 : parseInt(res[4])) : res[4], res[5]) :
            new Date(res[3], res[2]-1, res[1], res[6] ? (res[6].toUpperCase() === 'PM' ? 12 : 0) + (res[4] === '12' ? 0 : parseInt(res[4])) : res[4], res[5])
            ).toISOString();
        }
    return value;
    });
