Utilizing the JSON.parse method in JavaScript in conjunction with an Ajax request while incorporating the escape character "\\n" for new line functionality

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

Edit: json file has this line:

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

I need to retrieve a valid JSON file through an ajax call.
Then parse the result using JSON.parse.

I'm confused about the behavior of the "\\n" escape character found in my JSON file.

When I use JSON.parse with the same values, it gives me different results.

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

My understanding is that JavaScript might be escaping (or unescaping?) the string before parsing it.

The issue arises when I try to do this:

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

Do I also need to escape the regex itself?

In summary: I want to load the .json file via Ajax. I expect JSON.parse to properly handle the "\\n" by converting it into a NewLine character.

Answer №1

Special thanks to Bergi for helping me realize that the issue was not with JSON.parse, but rather with the format of my json file. I mistakenly had "\\n" instead of "\n".

Check out this updated jsbin to see how JSON.parse now functions consistently across different scenarios: https://jsbin.com/xezipucili/1/edit?js,console
