2007-02-18
Public Domain
This file adds these methods to JavaScript:
array.toJSONString()
boolean.toJSONString()
date.toJSONString()
number.toJSONString()
object.toJSONString()
string.toJSONString()
These methods 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.
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;
});
It is expected that these methods will formally become part of the
JavaScript Programming Language in the Fourth Edition of the
ECMAScript standard in 2008.
