I am using Firefox's native JSON.parse() to parse some JSON strings that include regular expressions as values, for example:

var test = JSON.parse('{regex:/\d+/}');

The 'd' in the above throws an exception with JSON.parse(), but works fine when I use eval (which is what I'm trying to avoid).

What I want is to preserve the '' in the regex - is there some other JSON-friendly way to escape it?

You need to escape the escape backslashes already in there :) like this:

var test = JSON.parse('{regex:/\\d+/}');

You can test it a bit here: http://jsfiddle.net/h3rzE/
