JSON.parse导致意外的令牌错误消息

Question

对不起，这个问题可能会被问几百次，我寻找类似的问题，但我无法找到一个线索，为什么我仍然收到此错误。

当我尝试解析下面的特定字符串时，它会显示“语法错误：意外的标记”。这是JS代码：

var a = "[{"ltd":"40.88393692299686","lng":"29.40516471862793","country":"Türkiye","city":"İstanbul","address":"Tepeören Mh., 2. Caddesi, 41480 Istanbul-Istanbul Province, Turkey","title":"Indoor Life Facory","detail":"İTOSB 2.Cad. No.7 Tuzla/istanbul/Turkey","addressTypeId":1,"adressType":"Üretim Birimi"},{"ltd":"40.97575903170847","lng":"29.051960706710815","country":"Türkiye","city":"İstanbul","address":"Fenerbahçe Mh., Bağdat Avenue 184-190, 34724 Kadıköy-Istanbul Province, Turkey","title":"Indoor Life Head Office","detail":"Bağdat Cad. Heper Apt. \r\nNo:165/5 34730 \r\nSelamiçeşme/Kadıköy/İstanbul/Turkey","addressTypeId":2,"adressType":"İdari Birim"}]"; 
 
a = a.replace(/"/g, '"'); 
 
var jsonList = JSON.parse(a);

Answer 1

由于您有字符串中的;BağdatCad.HeperApt.\r\n，这是导致错误，它显示无效JSON。你需要用正则表达式替换空格或空白字符串。所以正确的代码会是。

var a = "[{"ltd":"40.88393692299686","lng":"29.40516471862793","country":"Türkiye","city":"İstanbul","address":"Tepeören Mh., 2. Caddesi, 41480 Istanbul-Istanbul Province, Turkey","title":"Indoor Life Facory","detail":"İTOSB 2.Cad. No.7 Tuzla/istanbul/Turkey","addressTypeId":1,"adressType":"Üretim Birimi"},{"ltd":"40.97575903170847","lng":"29.051960706710815","country":"Türkiye","city":"İstanbul","address":"Fenerbahçe Mh., Bağdat Avenue 184-190, 34724 Kadıköy-Istanbul Province, Turkey","title":"Indoor Life Head Office","detail":"Bağdat Cad. Heper Apt. \r\nNo:165/5 34730 \r\nSelamiçeşme/Kadıköy/İstanbul/Turkey","addressTypeId":2,"adressType":"İdari Birim"}]"; 
 
a = a.replace(/"/g, '"'); 
 
a = a.replace(/(?:\r\n|\r|\n)/g, ''); 
 
console.log(a); 
 
var jsonList = JSON.parse(a);

Answer 2

您的JSON是无效的（jsonlint.com）。

您也需要用\\n替换新的行。

// additional replace func call 
a = a.replace(/(?:\r\n|\r|\n)/g, '\\n'); 

Answer 3

您的文字上有新行：Apt. \r\nNo:165/。 （请注意，JavaScript解析器会将JavaScript源代码解析为字符串，它们将转换为实际的新行）。

这些在JSON字符串中是不允许的，必须用换码序列替换。
