带有Ajax请求和“ \\\\ n”换行符的Javascript JSON.parse函数

Question

https://jsbin.com/zuhatujoqo/1/edit?js,console

Edit: json file has this line:

{"pd":"ciao \\n ste"}

I'm requesting a valid json file with an ajax call.
Then JSON.parse the result.

I don't understand what is happening with the "\\\\n" escaped new line char coming from my json file.

JSON.parse is giving me different result if i feed it with the same values.

var result = JSON.parse(data);
console.log(result);
var result2 = JSON.parse('{"pd":"ciao \\n ste"}');
console.log(result2);

As i understand it may be related to the fact that javascript before and then parse are escaping ( or unescaping ?? ) the string.

The problem is that i also don't understand this:

result = result.replace(/\\n/g, "<br />");

do i also have to escape the regex itself?

Sum: I want to use the .json file loaded via Ajax. I want the JSON.parse to do his job and unescape the "\\\\n" returning the NewLine char.

Answer 1

Thanks to the answers Bergi gave me, i now understand that the JSON.parse was already doing his job. It was my fault, i was providing a json file with "\\\\n" inside instead of just "\\n".

Here an updated jsbin where you can see that now JSON.parse acts the same in different scenario. https://jsbin.com/xezipucili/1/edit?js,console
