+ + + static + + Class JSON + + + +

+ + + + + +
+

The JSON module adds support for serializing JavaScript objects into +JSON strings and parsing JavaScript objects from strings in JSON format.

+

The JSON namespace is added to your YUI instance including static methods +Y.JSON.parse(..) and Y.JSON.stringify(..).

+

The functionality and method signatures follow the ECMAScript 5 +specification. In browsers with native JSON support, the native +implementation is used.

+

The json module is a rollup of json-parse and +json-stringify.

+

As their names suggest, json-parse adds support for parsing +JSON data (Y.JSON.parse) and json-stringify for serializing +JavaScript data into JSON strings (Y.JSON.stringify). You may choose to +include either of the submodules individually if you don't need the +complementary functionality, or include the rollup for both.

Properties

+
+
+

_BRACKETS + - private {RegExp} +

+
+
+ Third step in the safety evaluation. Regex used to remove all open +square brackets following a colon, comma, or at the beginning of the +string. +
+
+ + + + +
+
+
+

_CHARS + - protected static {Object} +

+
+
+ Character substitution map for common escapes and special characters. +
+
+ + + + +
+
+
+

_ESCAPES + - private {RegExp} +

+
+
+ First step in the safety evaluation. Regex used to replace all escape +sequences (i.e. "\\", etc) with '@' characters (a non-JSON character). +
+
+ + + + +
+
+
+

_INVALID + - private {RegExp} +

+
+
+ Final step in the safety evaluation. Regex used to test the string left +after all previous replacements for invalid characters. +
+
+ + + + +
+
+
+

_SIMPLE + - private {RegExp} +

+
+
+ Test for JSON string of simple data string, number, boolean, or null. +E.g. '"some string"', "true", "false", "null", or numbers "-123e+7" +This was needed for some WIP native implementations (FF3.1b2) but may be +unnecessary now. +
+
+ + + + +
+
+
+

_SPECIAL_CHARS + - protected {RegExp} +

+
+
+ Regex used to capture characters that need escaping before enclosing +their containing string in quotes. +
+
+ + + + +
+
+
+

_UNICODE_EXCEPTIONS + - private {RegExp} +

+
+
+ Replace certain Unicode characters that JavaScript may handle incorrectly +during eval--either by deleting them or treating them as line +endings--with escape sequences. +IMPORTANT NOTE: This regex will be used to modify the input if a match is +found. +
+
+ + + + +
+
+
+

_VALUES + - private {RegExp} +

+
+
+ Second step in the safety evaluation. Regex used to replace all simple +values with ']' characters. +
+
+ + + + +
+
+
+

Native + - private {Object} +

+
+
+ Alias to native browser implementation of the JSON object if available. +
+
+ + + + +
+
+
+
+ +
+ +
+
+

Methods

+
+
+

+ _revive

+
+ + private + + + MIXED + _revive + ( + + + data + + + , + reviver + + + ) + + +
+ Traverses nested objects, applying a reviver function to each (key,value) +from the scope if the key:value's containing object. The value returned +from the function will replace the original value in the key:value pair. +If the value returned is undefined, the key will be omitted from the +returned object. +
+ +
+ +
+
Parameters:
+
+ data + <MIXED> + + Any JavaScript data +
+
+ reviver + <Function> + + filter or mutation function +
+
+ +
+
Returns: + + MIXED +
+
The results of the filtered data
+
+ + + + +
+ +
+
+
+
+

+ dateToString

+
+ + + static + + String + dateToString + ( + + + d + + + ) + + +
+ Serializes a Date instance as a UTC date string. Used internally by +stringify. Override this method if you need Dates serialized in a +different format. +
+ +
+ +
+
Parameters:
+
+ d + <Date> + + The Date to serialize +
+
+ +
+
Returns: + + String +
+
stringified Date in UTC format YYYY-MM-DDTHH:mm:SSZ
+
+ + + + +
+ +
+
+
+
+

+ escapeException

+
+ + private + + + String + escapeException + ( + + + c + + + ) + + +
+ Replaces specific unicode characters with their appropriate \unnnn +format. Some browsers ignore certain characters during eval. +
+ +
+ +
+
Parameters:
+
+ c + <String> + + Unicode character +
+
+ +
+
Returns: + + String +
+
the \unnnn escapement of the character
+
+ + + + +
+ +
+
+
+
+

+ parse

+
+ + + static + + MIXED + parse + ( + + + s + + + , + reviver + + + ) + + +
+ Parse a JSON string, returning the native JavaScript representation. +
+ +
+ +
+
Parameters:
+
+ s + <string> + + JSON string data +
+
+ reviver + <function> + + (optional) function(k,v) passed each key value +pair of object literals, allowing pruning or altering values +
+
+ +
+
Returns: + + MIXED +
+
the native JavaScript representation of the JSON string
+
+ + + + +
+ +
+
+
+
+

+ stringify

+
+ + + static + + string + stringify + ( + + + o + + + , + w + + + , + ind + + + ) + + +
+

Converts an arbitrary value to a JSON string representation.

+

Objects with cyclical references will trigger an exception.

+

If a whitelist is provided, only matching object keys will be +included. Alternately, a replacer function may be passed as the +second parameter. This function is executed on every value in the +input, and its return value will be used in place of the original value. +This is useful to serialize specialized objects or class instances.

+

If a positive integer or non-empty string is passed as the third +parameter, the output will be formatted with carriage returns and +indentation for readability. If a String is passed (such as "\t") it +will be used once for each indentation level. If a number is passed, +that number of spaces will be used.

+
+ +
+ +
+
Parameters:
+
+ o + <MIXED> + + any arbitrary value to convert to JSON string +
+
+ w + <Array|Function> + + (optional) whitelist of acceptable object +keys to include, or a replacer function to modify the +raw value before serialization +
+
+ ind + <Number|String> + + (optional) indentation character or depth of +spaces to format the output. +
+
+ +
+
Returns: + + string +
+
JSON string representation of the input
