/* var myJSONObject = {"bindings": [ {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"}, {"ircEvent": "PRIVMSG", "method": "deleteURI", "regex": "^delete.*"}, {"ircEvent": "PRIVMSG", "method": "randomURI", "regex": "^random.*"} ] }; In this example, an object is created containing a single member "bindings" , which contains an array containing three objects, each containing "ircEvent" , "method", and "regex" members. Members can be retrieved using dot or subscript operators. myJSONObject.bindings[0].method // "newURI" To convert a JSON text into an object, use the eval() function. eval() invokes the JavaScript compiler. Since JSON is a proper subset of JavaScript, the compiler will correctly parse the text and produce an object structure. var myObject = eval('(' + myJSONtext + ')'); The eval function is very fast. However, it can compile and execute any JavaScript program, so there can be security issues. The use of eval is indicated when the source is trusted. This is commonly the case in web applications when a web server is providing both the base page and the JSON data. There are cases where the source is not trusted. In particular, clients should never be trusted. When security is a concern it is better to use a JSON parser. A JSON parser will only recognize JSON text and so is much safer: var myObject = myJSONtext.parseJSON(); A JSON stringifier goes in the opposite direction, converting JavaScript data structures into JSON text. JSON does not support cyclic data structures, so be careful to not give cyclical structures to the JSON stringifier. var myJSONText = myObject.toJSONString(); */ /* json.js 2006-04-28 This file adds these methods to JavaScript: object.toJSONString() This method produces a JSON text from an object. The object must not contain any cyclical references. array.toJSONString() This method produces a JSON text from an array. The array must not contain any cyclical references. string.parseJSON() This method parses a JSON text to produce an object or array. It will return false if there is an error. */ (function () { var m = { '\b': '\\b', '\t': '\\t', '\n': '\\n', '\f': '\\f', '\r': '\\r', '"' : '\\"', '\\': '\\\\' }, s = { array: function (x) { var a = ['['], b, f, i, l = x.length, v; for (i = 0; i < l; i += 1) { v = x[i]; f = s[typeof v]; if (f) { v = f(v); if (typeof v == 'string') { if (b) { a[a.length] = ','; } a[a.length] = v; b = true; } } } a[a.length] = ']'; return a.join(''); }, 'boolean': function (x) { return String(x); }, 'null': function (x) { return "null"; }, number: function (x) { return isFinite(x) ?
