|

This file adds these methods to JavaScript: |
||||
|
||||
object.toJSONString(whitelist) |
||||
This method 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; |
||||
}); |
||||

|
||||
|
||||
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. 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(' && |
