Javascript-如何遍历无效的JSON

Question

我有这样的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
   }
}

这个JSON是无效的，但是我在这种形式下得到它，我无法解析，因为它不是一个有效的JSON，我不能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？ 循环这个JSON的任何方法？

Answer 1

通过您给出的示例，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。

我没有测试它，但它可能是这样的：

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

祝好运。

更新

正如使者提到的那样，删除新行会导致数据丢失。 因此，您可以使用“JSON转义的新行”替换新行。 请参阅： https ： //stackoverflow.com/a/42073/2911452

Answer 2

我只会替换有问题的行结尾

 data = data.replace(/\\{(lastname|company|address_1|address_2|postcode)\\}\\s?\\n/ig,'{$1}\\\\\\\\n'); console.log(JSON.parse(data)); // Object {2070: Object, 2071: Object}
