Question

After upgrading to jquery 1.4.1 i noticed there was an error anytime i tried calling json.parse. The issue is part of the regex used in json. it uses a $ in the pattern that conflicts with JQuery’s $ shortcut.

I don’t want to use the non-conflict option with jquery because i have tons of places i’d have to replace the $ with the new corrected shortcut.

Is there a way to wrap a regex pattern in single quotes or something so the pattern string is handled as literally a string?

Broken section in json-2.0.js: (fails on the $)

if (/^[\],:{}\s]*$/.
test(text.replace(/\\(?:["\\\/bfnrt]|u[0-9a-fA-F]{4})/g, '@').
replace(/"[^"\\\n\r]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g, ']').
replace(/(?:^|:|,)(?:\s*\[)+/g, ''))) {
.....
}

Thanks

Update:

The problem was not as it appeared and didn’t have to do with a $ conflict. From the OP:

The error was bombing on test.replace because the object that was passed in was already deserialized so the method replace was not found. I guess upgrading to JQuery 1.4.1 had some changes in the way the result object is handled on the success event of the $.ajax function.

Here’s a page that pulls in jQuery 1.4.1 and json2.js, and it calls JSON.parse(), and it gets no exceptions or errors: http://gutfullofbeer.net/json.html
