如何在 JSON 字符串中转义双引号

Question

I am trying to do parse a string Hello " test containing double quote which already escaped, but I get an error

JSON.parse(`{"x":"Hello \" test "}`)

Is there anything I missed here?

 JSON.parse(`{"x":"Hello \" test "}`)

Answer 1

You just need to escape the backslash \ , so it turns into two backslashes \\

 console.log(JSON.parse('{"x":"Hello \\" test"}'))

Answer 2

 let mydata = `{"x":"Hello \" test "}` let escapeJsonFunc = function(str) { return str.replace(/\\/g,'\\'); }; console.log( escapeJsonFunc(mydata) )
