现在var str = '{"Language":"en","Type":"General","Text":""Mela" means "apple" in Italian"}';会抛出此错误

JSON.parse(str)

现在替换引号会转义整个字符串，并且已解析的JSON不再可用

Uncaught SyntaxError: Unexpected token M in JSON at position 43

str = str.replace(/\\([\s\S])|(")/g,"\\$1$2");

以下其他解决方案似乎无法在此方案中使用

How to escape a JSON string containing newline characters using JavaScript?

Answer 1

您需要在字符串中的每个双引号之前添加反斜杠：

const str = '{"Language":"en","Type":"General","Text": "\\"Mela\\" means \\"apple\\" in Italian"}';

const obj = JSON.parse(str)
console.log(obj.Text)

Answer 2

在JSON中，你不要逃避属性名称的双引号或属性值的乞讨，只要逃避属性值内的内容：

{\"Text\":\"\"Mela\" means ....

应该是这样的：

{"Text":"\"Mela\" means ....

Answer 3

这可以通过多次替换来完成：

var str = '{"Language":"en","Type":"General","Text":""Mela" means "apple" in Italian"}';
str = str.replace(/"/,"'"); //Replace all " with '

str = str.replace(/{'/,'{"') //Restore " to start of JSON
str = str.replace(/','/,'","'); //Restore " around JSON , separators
str = str.replace(/':'/,'":"'); //Restore " around JSON : separators
str = str.replace(/'}/,'"}'); //Restore " to end of JSON
str = str.replace(/'/,'\"'); //All remaining ' must be inside of data, so replace with properly escaped \"

console.log(str);

编辑：此解决方案的一个问题是，它还将替换文本中的原始“字符”。
