Javascript regex ends with pattern -

i'm trying write regex in javascript identify string representations of arbitrary javascript functions found in json, ie.

{ "key": "function() { homecoming 'i function'; }" }

it's easy plenty identify start, can't figure out how identify ending double quotes since function might contain escaped double quotes. best seek far is

/"\s*function\(.*\)[^"]*/g

which works nicely if there no double quotes in function string. end of json key value end double quote , subsequent comma or closing bracket. there way retrieve characters (including newline?) until negated pattern such

not "/s*, , not "/s*}

... or need take different approach without regex?

here's current test info i'm working with: http://regexr.com/39pvi

seems want this,

"\s*function\(.*\)(?:\\.|[^\\"])*

it matches inbetween \" escaped double quotes.
