See + http://yuiblog.com/blog/2006/09/26/for-in-intrigue/ + + This file creates a global JSON object containing two methods: stringify + and parse. + + JSON.stringify(value, replacer, space) + value any JavaScript value, usually an object or array. + + replacer an optional parameter that determines how object + values are stringified for objects. It can be a + function or an array of strings. + + space an optional parameter that specifies the indentation + of nested structures. If it is omitted, the text will + be packed without extra whitespace. If it is a number, + it will specify the number of spaces to indent at each + level. If it is a string (such as '\t' or ' '), + it contains the characters used to indent at each level. + + This method produces a JSON text from a JavaScript value. + + When an object value is found, if the object contains a toJSON + method, its toJSON method will be called and the result will be + stringified. A toJSON method does not serialize: it returns the + value represented by the name/value pair that should be serialized, + or undefined if nothing should be serialized. The toJSON method + will be passed the key associated with the value, and this will be + bound to the object holding the key. + + For example, this would serialize Dates as ISO strings. + + Date.prototype.toJSON = function (key) { + function f(n) { + // Format integers to have at least two digits. + return n < 10 ? '0' + n : n; + } + + return this.getUTCFullYear() + '-' + + f(this.getUTCMonth() + 1) + '-' + + f(this.getUTCDate()) + 'T' + + f(this.getUTCHours()) + ':' + + f(this.getUTCMinutes()) + ':' + + f(this.getUTCSeconds()) + 'Z'; + }; + + You can provide an optional replacer method. It will be passed the + key and value of each member, with this bound to the containing + object. The value that is returned from your method will be + serialized. If your method returns undefined, then the member will + be excluded from the serialization. + + If the replacer parameter is an array of strings, then it will be + used to select the members to be serialized. It filters the results + such that only members with keys listed in the replacer array are + stringified. + + Values that do not have JSON representations, such as undefined or + functions, will not be serialized. Such values in objects will be + dropped; in arrays they will be replaced with null. You can use + a replacer function to replace those with JSON values. + JSON.stringify(undefined) returns undefined. + + The optional space parameter produces a stringification of the + value that is filled with line breaks and indentation to make it + easier to read. + + If the space parameter is a non-empty string, then that string will + be used for indentation. If the space parameter is a number, then + the indentation will be that many spaces. + + Example: + + text = JSON.stringify(['e', {pluribus: 'unum'}]); + // text is '["e",{"pluribus":"unum"}]' + + + text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); + // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' + + text = JSON.stringify([new Date()], function (key, value) { + return this[key] instanceof Date ? + 'Date(' + this[key] + ')' : value; + }); + // text is '["Date(---current time---)"]' + + + JSON.parse(text, reviver) + This method parses a JSON text to produce an object or array. + It can throw a SyntaxError exception. + + The optional reviver parameter is a function that can filter and + transform the results.
