Answer 1

xác minh chuỗi json của bạn. Nếu nó là ok thử này:

var jsonStr="your json string"; 
var json=JSON.stringify(jsonStr); 
json=JSON.parse(json) 

Answer 2

Khi bạn gõ một chuỗi trong javascript, \ được coi là ký tự thoát, trong khi bạn cần nó trong thực tế của bạn là \ và không phải là ký tự thoát.

Bạn cần phải thay đổi \" để \\" và \n-\\n, trong khi vẫn giữ \' vì nó đã là một nhân vật thoát và nó sẽ được phân tích ổn
