|
||||
|
||||
|
||||
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 value
|
||||
|
||||
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. 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 the structure is not modified.
|
||||
If it returns undefined then the member is deleted.
|
||||
|
||||
Example:
|
||||
|
||||
// Parse the text. Values that look like ISO date strings will
|
||||
// be converted to Date objects.
|
||||
|
||||
myData = JSON.parse(text, function (key, value) {
|
||||
var a;
|
||||
if (typeof value === 'string') {
|
||||
a =
|
||||
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
|
||||
if (a) {
|
||||
return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
|
||||
+a[5], +a[6]));
|
||||
}
|
||||
}
|
||||
return value;
|
||||
});
|
||||
|
||||
myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
|
||||
var d;
|
||||
if (typeof value === 'string' &&
|
||||
value.slice(0, 5) === 'Date(' &&
|
||||
value.slice(-1) === ')') {
|
||||
d = new Date(value.slice(5, -1));

if (d) {

# JSON 3 #
|
||||
|
||||
|
||||
|
||||
**JSON 3** is a modern JSON implementation compatible with a variety of JavaScript platforms, including Internet Explorer 6, Opera 7, Safari 2, and Netscape 6. The current version is **3.2.4**.
|
||||
|
||||
- [Development Version](http://bestiejs.github.com/json3/lib/json3.js) *(36.5 KB; uncompressed with comments)*
|
||||
- [Production Version](http://bestiejs.github.com/json3/lib/json3.min.js) *(3.0 KB; compressed and `gzip`-ped)*
|
||||
|
||||
[JSON](http://json.org/) is a language-independent data interchange format based on a loose subset of the JavaScript grammar. Originally popularized by [Douglas Crockford](http://www.crockford.com/), the format was standardized in the [fifth edition](http://es5.github.com/) of the ECMAScript specification. The 5.1 edition, ratified in June 2011, incorporates several modifications to the grammar pertaining to the serialization of dates.
|
||||
|
||||
JSON 3 exposes two functions: `stringify()` for [serializing](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/JSON/stringify) a JavaScript value to JSON, and `parse()` for [producing](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/JSON/parse) a JavaScript value from a JSON source string. It is a **drop-in replacement** for [JSON 2](http://json.org/js). The functions behave exactly as described in the ECMAScript spec, **except** for the date serialization discrepancy noted below.
|
||||
|
||||
The JSON 3 parser does **not** use `eval` or regular expressions. This provides security and performance benefits in obsolete and mobile environments, where the margin is particularly significant. The complete [benchmark suite](http://jsperf.com/json3) is available on [jsPerf](http://jsperf.com/).
|
||||
|
||||
The project is [hosted on GitHub](http://git.io/json3), along with the [unit tests](http://bestiejs.github.com/json3/test/test_browser.html). It is part of the [BestieJS](https://github.com/bestiejs) family, a collection of best-in-class JavaScript libraries that promote cross-platform support, specification precedents, unit testing, and plenty of documentation.
|
||||
|
||||
# Changes from JSON 2 #
|
||||
|
||||
JSON 3...
|
||||
|
||||
* Correctly serializes primitive wrapper objects.
|
||||
* Throws a `TypeError` when serializing cyclic structures (JSON 2 recurses until the call stack overflows).
|
||||
* Utilizes **feature tests** to detect broken or incomplete *native* JSON implementations (JSON 2 only checks for the presence of the native functions). The tests are only executed once at runtime, so there is no additional performance cost when parsing or serializing values.
|
||||
|
||||
**As of v3.2.3**, JSON 3 is compatible with [Prototype](http://prototypejs.org) 1.6.1 and older.
|
||||
|
||||
In contrast to JSON 2, JSON 3 **does not**...
|
||||
|
||||
* Add `toJSON()` methods to the `Boolean`, `Number`, and `String` prototypes. These are not part of any standard, and are made redundant by the design of the `stringify()` implementation.
|
||||
* Add `toJSON()` or `toISOString()` methods to `Date.prototype`. See the note about date serialization below.
|
||||
|
||||
## Date Serialization
|
||||
|
||||
**JSON 3 deviates from the specification in one important way**: it does not define `Date#toISOString()` or `Date#toJSON()`. This preserves CommonJS compatibility and avoids polluting native prototypes. Instead, date serialization is performed internally by the `stringify()` implementation: if a date object does not define a custom `toJSON()` method, it is serialized as a [simplified ISO 8601 date-time string](http://es5.github.com/#x15.9.1.15).
|
||||
|
||||
**Several native `Date#toJSON()` implementations produce date time strings that do *not* conform to the grammar outlined in the spec**. For instance, all versions of Safari 4, as well as JSON 2, fail to serialize extended years correctly. Furthermore, JSON 2 and older implementations omit the milliseconds from the date-time string (optional in ES 5, but required in 5.1). Finally, in all versions of Safari 4 and 5, serializing an invalid date will produce the string `"Invalid Date"`, rather than `null`. Because these environments exhibit other serialization bugs, however, JSON 3 will override the native `stringify()` implementation.
|
||||
|
||||
Portions of the date serialization code are adapted from the [`date-shim`](https://github.com/Yaffle/date-shim) project.
|
||||

||||
# Usage #
|
||||
|
||||
## Web Browsers
|
||||
|
||||
<script src="http://bestiejs.github.com/json3/lib/json3.min.js"></script>
|
||||
<script>
|
||||
JSON.stringify({"Hello": 123});
|
||||
// => '{"Hello":123}'
|
||||
JSON.parse("[[1, 2, 3], 1, 2, 3, 4]", function (key, value) {
|
||||
if (typeof value == "number") {
|
||||
value = value % 2 ? "Odd" : "Even";
|
||||
}
|
||||
return value;
|
||||
});
|
||||
// => [["Odd", "Even", "Odd"], "Odd", "Even", "Odd", "Even"]
|
||||
</script>
|
||||
|
||||
## CommonJS Environments
|
||||
|
||||
var JSON3 = require("./path/to/json3");
|
||||
JSON3.parse("[1, 2, 3]");
|
||||
// => [1, 2, 3]
|
||||
|
||||
## JavaScript Engines
|
||||
|
||||
load("path/to/json3.js");
|
||||
JSON.stringify({"Hello": 123, "Good-bye": 456}, ["Hello"], "\t");
|
||||
// => '{\n\t"Hello": 123\n}'
|
||||
|
||||
# Compatibility #
|
||||
|
||||
JSON 3 has been **tested** with the following web browsers, CommonJS environments, and JavaScript engines.
|
||||
|
||||
## Web Browsers
|
||||
|
||||
- Windows [Internet Explorer](http://www.microsoft.com/windows/internet-explorer), version 6.0 and higher
|
||||
- Mozilla [Firefox](http://www.mozilla.com/firefox), version 1.0 and higher
|
||||
- Apple [Safari](http://www.apple.com/safari), version 2.0 and higher
|
||||
- [Opera](http://www.opera.com) 7.02 and higher
|
||||
- [Mozilla](http://sillydog.org/narchive/gecko.php) 1.0, [Netscape](http://sillydog.org/narchive/) 6.2.3, and [SeaMonkey](http://www.seamonkey-project.org/) 1.0 and higher
|
||||
|
||||
## CommonJS Environments
|
||||
|
||||
- [Node](http://nodejs.org/) 0.2.6 and higher
|
||||
- [RingoJS](http://ringojs.org/) 0.4 and higher
|
||||
- [Narwhal](http://narwhaljs.org/) 0.3.2 and higher
|
||||
|
||||
## JavaScript Engines
|
||||
|
||||
- Mozilla [Rhino](http://www.mozilla.org/rhino) 1.5R5 and higher
|
||||
- WebKit [JSC](https://trac.webkit.org/wiki/JSC)
|
||||
- Google [V8](http://code.google.com/p/v8)
|
||||
|
||||
## Known Incompatibilities
|
||||
|
||||
* Attempting to serialize the `arguments` object may produce inconsistent results across environments due to specification version differences. As a workaround, please convert the `arguments` object to an array first: `JSON.stringify([].slice.call(arguments, 0))`.
|
||||
|
||||
## Required Native Methods
|
||||
|
||||
JSON 3 assumes that the following methods exist and function as described in the ECMAScript specification:
|
||||
|
||||
- The `Number`, `String`, `Array`, `Object`, `Date`, `SyntaxError`, and `TypeError` constructors.
|
||||
- `String.fromCharCode`
|
||||
- `Object#toString`
|
||||
- `Function#call`
|
||||
- `Math.floor`
|
||||
- `Number#toString`
|
||||
- `Date#valueOf`
|
||||
- `String.prototype`: `indexOf`, `charCodeAt`, `charAt`, `slice`.
|
||||
- `Array.prototype`: `push`, `pop`, `join`.
|
||||
