• javascript
• google-chrome
• console

• I suppose something like x.replace(/\n/g,"\\n") is out of the question? (Or use FF, which seems to do what you want by default.) – nnnnnn Commented Oct 9, 2012 at 4:19
• @nnnnnn: That's the behavior that I'm trying to emulate in Chrome. There doesn't seem to be a hidden switch anywhere, though. – Blender Commented Oct 9, 2012 at 4:24
• Yeah, I figured. I guess worst-case if you need to copy-paste the value or something you could manually enter a .replace() statement as per my previous ment, or define a function to do it so you don't have to type it every time. (Clunky? Yes, I admit it.) – nnnnnn Commented Oct 9, 2012 at 4:32
• can you tell us how to display those characters in firefox? I'm around this issue for 20 minutes and I can't get by googling it a good answer for this problem – João Pimentel Ferreira Commented Jan 29, 2018 at 13:51
• @JoãoPimentelFerreira: Firefox stopped displaying strings like this starting with 23.0. – Blender Commented Jan 29, 2018 at 18:38

You can use encodeURI for showing the hidden stuffs.

Something like this encodeURI("a\nb") instead of "a\nb".

In node.js, require("util").inspect does something very similar. I haven't been able to find a browser equivalent, though fortunately the node.js implementation is fairly straight forward:

JSON.stringify(value)
    .replace(/^"|"$/g, '')
    .replace(/'/g, "\\'")
    .replace(/\\"/g, '"')
;

In your case, just JSON.stringify(value) should work.

You can stringify the value to get these invisible characters:

> JSON.stringify("a\nb")
<- ""a\nb""

You can try this way

var x = 'a\\nb';

EDIT:

You can use hexadecimal character in string.

\ = '\u005C'
> var x = 'a\u005Cnb';
> x
<- "a\nb"
> x === "a\nb" is false.
> x === "a\\nb" is true or x === 'a\u005Cnb' is true.

You can take a look at links.
