Unfortunately I do not see jQuery providing similar function, while
Prototype does:
http://www.prototypejs.org/api/string/isJSON
  
I've found in the source the function you've linked above, I've rewrited 
to make it works with jquery:

jQuery.isJson = function(str) {
   if (jQuery.trim(str) == '') return false;
   str = str.replace(/\\./g, '@').replace(/"[^"\\\n\r]*"/g, '');
   return (/^[,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]*$/).test(str);    
}


After including this piece of code (after jquery source), you can call :

$.isJson(mystring);

Bye :-)
