 17 | 
 18 | 
 19 |     This file creates a global JSON object containing two methods: stringify
 20 |     and parse.
 21 | 
 22 |         JSON.stringify(value, replacer, space)
 23 |             value       any JavaScript value, usually an object or array.
 24 | 
 25 |             replacer    an optional parameter that determines how object
 26 |                         values are stringified for objects. It can be a
 27 |                         function or an array of strings.
 28 | 
 29 |             space       an optional parameter that specifies the indentation
 30 |                         of nested structures. If it is omitted, the text will
 31 |                         be packed without extra whitespace. If it is a number,
 32 |                         it will specify the number of spaces to indent at each
 33 |                         level. If it is a string (such as '\t' or '&nbsp;'),
 34 |                         it contains the characters used to indent at each level.
 35 | 
 36 |             This method produces a JSON text from a JavaScript value.
 37 | 
 38 |             When an object value is found, if the object contains a toJSON
 39 |             method, its toJSON method will be called and the result will be
 40 |             stringified. A toJSON method does not serialize: it returns the
 41 |             value represented by the name/value pair that should be serialized,
 42 |             or undefined if nothing should be serialized. The toJSON method
 43 |             will be passed the key associated with the value, and this will be
 44 |             bound to the value
 45 | 
 46 |             For example, this would serialize Dates as ISO strings.
 47 | 
 48 |                 Date.prototype.toJSON = function (key) {
 49 |                     function f(n) {
 50 |                         // Format integers to have at least two digits.
 51 |                         return n < 10 ? '0' + n : n;
 52 |                     }
 53 | 
 54 |                     return this.getUTCFullYear()   + '-' +
 55 |                          f(this.getUTCMonth() + 1) + '-' +
 56 |                          f(this.getUTCDate())      + 'T' +
 57 |                          f(this.getUTCHours())     + ':' +
 58 |                          f(this.getUTCMinutes())   + ':' +
 59 |                          f(this.getUTCSeconds())   + 'Z';
 60 |                 };
 61 | 
 62 |             You can provide an optional replacer method. It will be passed the
 63 |             key and value of each member, with this bound to the containing
 64 |             object. The value that is returned from your method will be
 65 |             serialized. If your method returns undefined, then the member will
 66 |             be excluded from the serialization.
 67 | 
 68 |             If the replacer parameter is an array of strings, then it will be
 69 |             used to select the members to be serialized. It filters the results
 70 |             such that only members with keys listed in the replacer array are
 71 |             stringified.
 72 | 
 73 |             Values that do not have JSON representations, such as undefined or
 74 |             functions, will not be serialized. Such values in objects will be
 75 |             dropped; in arrays they will be replaced with null. You can use
 76 |             a replacer function to replace those with JSON values.
 77 |             JSON.stringify(undefined) returns undefined.
 78 | 
 79 |             The optional space parameter produces a stringification of the
 80 |             value that is filled with line breaks and indentation to make it
 81 |             easier to read.
 82 | 
 83 |             If the space parameter is a non-empty string, then that string will
 84 |             be used for indentation. If the space parameter is a number, then
 85 |             the indentation will be that many spaces.
 86 | 
 87 |             Example:
 88 | 
 89 |             text = JSON.stringify(['e', {pluribus: 'unum'}]);
 90 |             // text is '["e",{"pluribus":"unum"}]'
 91 | 
 92 | 
 93 |             text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
 94 |             // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
 95 | 
 96 |             text = JSON.stringify([new Date()], function (key, value) {
 97 |                 return this[key] instanceof Date ?
 98 |                     'Date(' + this[key] + ')' : value;
 99 |             });
100 |             // text is '["Date(---current time---)"]'
101 | 
102 | 
103 |         JSON.parse(text, reviver)
104 |             This method parses a JSON text to produce an object or array.
105 |             It can throw a SyntaxError exception.
106 | 
107 |             The optional reviver parameter is a function that can filter and
108 |             transform the results. It receives each of the keys and values,
109 |             and its return value is used instead of the original value.
110 |             If it returns what it received, then the structure is not modified.
111 |             If it returns undefined then the member is deleted.
112 | 
113 |             Example:
114 | 
115 |             // Parse the text. Values that look like ISO date strings will
116 |             // be converted to Date objects.
117 | 
118 |             myData = JSON.parse(text, function (key, value) {
119 |                 var a;
120 |                 if (typeof value === 'string') {
121 |                     a =
122 | /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
123 |                     if (a) {
124 |                         return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
125 |                             +a[5], +a[6]));
126 |                     }
127 |                 }
128 |                 return value;
129 |             });
130 | 
131 |             myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
132 |                 var d;
