JSON static objectS2C Home « Globals « JSON

A static class containing methods for parsing and forming JSON notation, which is an acronym for JavaScript Object Notation.

Description

The JSON format allows us to serialize objects that can be passed across different user platforms in a language dependant way.

• The JSON global object is a static object which means we cannot instantiate objects of type JSON.
• The two methods of this class are also static and so we access these using JSON followed by the name of the method we wish to use.

Syntax

Parameters

Class Properties

None.

Instance Properties

Examples

// Store properties in an array.
var jsonMethods = new Array(8);
var jsonMethods = new Array(10);
jsonMethods[0] = 'Parse some data: ';   
jsonMethods[1] = JSON.parse('""'); // Empty String 
jsonMethods[2] = JSON.parse('"A string"'); // A String 
jsonMethods[3] = JSON.parse('[1, 2, 3, 4]'); // Single type array
jsonMethods[4] = JSON.parse('[1, "2", 3, "true"]'); // Multi type array
jsonMethods[5] = JSON.parse('null'); // null
jsonMethods[6] = 'Stringify some data: ';   
jsonMethods[7] = JSON.stringify('""'); // Empty String 
jsonMethods[8] = JSON.stringify('"A string"'); // A String 
jsonMethods[9] = JSON.stringify('[1, 2, 3, 4]'); // Single type array
jsonMethods[10] = JSON.stringify('[1, "2", 3, "true"]'); // Multi type array
jsonMethods[11] = JSON.stringify('null'); // null
alert(jsonMethods);
