/* json.js 2008-03-14 Public Domain No warranty expressed or implied. Use at your own risk. This file has been superceded by http://www.JSON.org/json2.js See http://www.JSON.org/js.html This file adds these methods to JavaScript: array.toJSONString(whitelist) boolean.toJSONString() date.toJSONString() number.toJSONString() object.toJSONString(whitelist) string.toJSONString() These methods produce a JSON text from a JavaScript value. It must not contain any cyclical references. Illegal values will be excluded. The default conversion for dates is to an ISO string. You can add a toJSONString method to any date object to get a different representation. The object and array methods can take an optional whitelist argument. A whitelist is an array of strings. If it is provided, keys in objects not found in the whitelist are excluded. string.parseJSON(filter) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional filter parameter is a function which can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. If a key contains the string 'date' then // convert the value to a date. myData = text.parseJSON(function (key, value) { return key.indexOf('date') >= 0 ? new Date(value) : value; }); It is expected that these methods will formally become part of the JavaScript Programming Language in the Fourth Edition of the ECMAScript standard in 2008. This file will break programs with improper for..in loops. See http://yuiblog.com/blog/2006/09/26/for-in-intrigue/ This is a reference implementation. You are free to copy, modify, or redistribute.
