Javascript-如何遍历无效的 JSON

Question

我有一个像这样的 JSON 数组

       {  
   "2070":{  
      "address_id":"2070",
      "firstname":"Simon",
      "lastname":"Hall",
      "company":"",
      "address_1":"",
      "address_2":"",
      "postcode":"44000",
      "city":"",
      "zone_id":"0",
      "zone":"",
      "zone_code":"",
      "country_id":"223",
      "country":"United States",
      "iso_code_2":"US",
      "iso_code_3":"USA",
      "address_format":"{firstname} {lastname} 
    {company} 
    {address_1} 
    {address_2} 
    {city}, {zone} {postcode} 
    {country}",
      "custom_field":false
   },
   "2071":{  
      "address_id":"2071",
      "firstname":"Simon",
      "lastname":"Hall",
      "company":"",
      "address_1":"TEST",
      "address_2":"",
      "postcode":"44000",
      "city":"New York",
      "zone_id":"3625",
      "zone":"Colorado",
      "zone_code":"CO",
      "country_id":"223",
      "country":"United States",
      "iso_code_2":"US",
      "iso_code_3":"USA",
      "address_format":"{firstname} {lastname} 
    {company} 
    {address_1} 
    {address_2} 
    {city}, {zone} {postcode} 
    {country}",
      "custom_field":false
   }
}

此 JSON 无效，但我以这种形式获取它，我无法解析它，因为它不是有效的 JSON，而且我无法从字符串中删除特殊字符。 如何从这个无效的 JSON 中提取特定索引的数据？ 有什么方法可以遍历这个 JSON？

Answer 1

对于您提供的示例，您可以简单地从字符串中删除所有换行符，从而生成有效的 JSON。

我没测试过，大概是这样的:

var json = "your json";
json = json.replace(/(?:\r\n|\r|\n)/g, '');

祝你好运。

正如 Emissary 提到的，删除新行会导致数据丢失。因此，您可以将新行替换为“JSON 转义新行”。请参阅:https://stackoverflow.com/a/42073/2911452
