JSON.parse导致意外令牌错误消息

Question

Sorry this question might be asked hundreds time, I looked for similar questions but I can not find a clue why I still receive this error.

When I try to parse this specific string below, it says "Syntax error: Unexpected token". This is JS code:

 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

Since you have ;BağdatCad.HeperApt.\\r\\n in string, that was causing error , it was showing invalid JSON . You need to replace them with space or blank string using regex. So Correct code would be.

 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

Your json is not valid ( jsonlint.com ).

you need to replace the new lines with \\\\n too.

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

Answer 3

Your text has new lines in it: Apt. \\r\\nNo:165/ Apt. \\r\\nNo:165/ . (Note, they will be converted to actual new lines with the JavaScript parser parses the JavaScript source code into the string).

These are not allowed in JSON strings and must be replaced by escape sequences.
