Escaping JSON and Regex

Question

I need a json-string to be used in a regex. Honestly I am a bit confused about all the escaping.. :)

I want to replace "\o/" by something else by regex. The source string should be in a JSON.

This is the JSON-String without escaping:

var emoticons=...
    + '{"img": "party.png","short": "\o/"},'
...

I tried to escape the slash and backslash to meet the regex' need but after that wasn't able to parse the JSON anymore:

var emoticons=...
    + '{"img": "party.png","short": "\\o\/"},'
...

How should the JSON-String look like?

Code:

var smilies = JSON.parse(emoticons);
text.replace(new RegExp(smilies.short,......);

You probably shouldn't apply the regex to the entire json string; parse the json, find the variable you want and only then apply the regex to the actual string; let your json serializer do the rest. — beerbajay, Feb 23 '14 at 11:10

@DeanTaylor No. It was not "Just" about escaping a regex but the combination regex/json ("double-escaping") — Ole Albers, Feb 23 '14 at 11:21
@OleAlbers it's a string, it doesn't matter that it is JSON, other than the input to the escaping is a JSON string, ultimately just a string to escape into the RegEx. — Dean Taylor, Feb 23 '14 at 11:24
@DeanTaylor I added the code, which should make it clearer. (But is solved nonetheless) — Ole Albers, Feb 23 '14 at 11:57
If you solved it, you should answer your own question, and accept it. — zord, Feb 23 '14 at 12:20
I hate answering myself, looks like clapping on my own shoulder... :) But well. did it — Ole Albers, Feb 23 '14 at 12:27
