 | 
	
		
			
				|  |  | + 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) {
