-
- This file creates a global JSON object containing three methods: stringify,
- parse, and quote.
-
-
- 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 without a toJSON
- method. It can be a function or an array.
-
- 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'), 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 object holding the key.
-
- This is the toJSON method added to Dates:
-
- function toJSON(key) {
- 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 no replacer parameter is provided, then a default replacer
- will be used:
-
- function replacer(key, value) {
- return Object.hasOwnProperty.call(this, key) ?
- value : undefined;
- }
-
- The default replacer is passed the key and value for each item in
- the structure. It excludes inherited members.
-
- If the replacer parameter is an array, 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 representaions, 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
- then 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]'
-
-
- 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;
- });
-
-
- JSON.quote(text)
- This method wraps a string in quotes, escaping some characters
- as needed.
-
-
- This is a reference implementation. You are free to copy, modify, or
- redistribute.
-
- USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD THIRD PARTY
- CODE INTO YOUR PAGES.
