USE AT YOUR OWN RISK. 8 9 See https://www.JSON.org/js.html 10 11 This file creates a global JSON object containing two methods: stringify 12 and parse. 13 14 JSON.stringify(value, replacer, space) 15 value any JavaScript value, usually an object or array. 16 17 replacer an optional parameter that determines how object 18 values are stringified for objects. It can be a 19 function or an array of strings. 20 21 space an optional parameter that specifies the indentation 22 of nested structures. If it is omitted, the text will 23 be packed without extra whitespace. If it is a number, 24 it will specify the number of spaces to indent at each 25 level. If it is a string (such as '\t' or ' '), 26 it contains the characters used to indent at each level. 27 28 This method produces a JSON text from a JavaScript value. 29 30 When an object value is found, if the object contains a toJSON 31 method, its toJSON method will be called and the result will be 32 stringified. A toJSON method does not serialize: it returns the 33 value represented by the name/value pair that should be serialized, 34 or undefined if nothing should be serialized. The toJSON method 35 will be passed the key associated with the value, and this will be 36 bound to the object holding the key. 37 38 For example, this would serialize Dates as ISO strings. 39 40 Date.prototype.toJSON = function (key) { 41 function f(n) { 42 // Format integers to have at least two digits. 43 return n < 10 ? '0' + n : n; 44 } 45 46 return this.getUTCFullYear() + '-' + 47 f(this.getUTCMonth() + 1) + '-' + 48 f(this.getUTCDate()) + 'T' + 49 f(this.getUTCHours()) + ':' + 50 f(this.getUTCMinutes()) + ':' + 51 f(this.getUTCSeconds()) + 'Z'; 52 }; 53 54 You can provide an optional replacer method. It will be passed the 55 key and value of each member, with this bound to the containing 56 object. The value that is returned from your method will be 57 serialized. If your method returns undefined, then the member will 58 be excluded from the serialization. 59 60 If the replacer parameter is an array of strings, then it will be 61 used to select the members to be serialized. It filters the results 62 such that only members with keys listed in the replacer array are 63 stringified. 64 65 Values that do not have JSON representations, such as undefined or 66 functions, will not be serialized. Such values in objects will be 67 dropped; in arrays they will be replaced with null. You can use 68 a replacer function to replace those with JSON values. 69 JSON.stringify(undefined) returns undefined. 70 71 The optional space parameter produces a stringification of the 72 value that is filled with line breaks and indentation to make it 73 easier to read. 74 75 If the space parameter is a non-empty string, then that string will 76 be used for indentation. If the space parameter is a number, then 77 the indentation will be that many spaces. 78 79 Example: 80 81 text = JSON.stringify(['e', {pluribus: 'unum'}]); 82 // text is '["e",{"pluribus":"unum"}]' 83 84 85 text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); 86 // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' 87 88 text = JSON.stringify([new Date()], function (key, value) { 89 return this[key] instanceof Date ? 90 'Date(' + this[key] + ')' : value; 91 }); 92 // text is '["Date(---current time---)"]' 93 94 95 JSON.parse(text, reviver) 96 This method parses a JSON text to produce an object or array. 97 It can throw a SyntaxError exception. 98 99 The optional reviver parameter is a function that can filter and 100 transform the results. It receives each of the keys and values, 101 and its return value is used instead of the original value. 102 If it returns what it received, then the structure is not modified. 103 If it returns undefined then the member is deleted. 104 105 Example: 106 107 // Parse the text. Values that look like ISO date strings will 108 // be converted to Date objects. 109 110 myData = JSON.parse(text, function (key, value) { 111 var a; 112 if (typeof value === 'string') { 113 a = 114/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); 115 if (a) { 116 return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], 117 +a[5], +a[6])); 118 } 119 } 120 return value; 121 }); 122 123 myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { 124 var d; 125 if (typeof value === 'string' && 126 value.slice(0, 5) === 'Date(' && 127 value.slice(-1) === ')') { 128 d = new Date(value.slice(5, -1)); 129 if (d) { 130 return d; 131 } 132 } 133 return value; 134 }); 135 136 137 This is a reference implementation.
