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) {
|
|
var d;
|
|
if (typeof value === 'string' &&
|
|
value.slice(0, 5) === 'Date(' &&
|
|
value.slice(-1) === ')') {
|
|
d = new Date(value.slice(5, -1));
|
|
if (d) {
|
|
return d;
|
|
}
|
|
}
|
|
return value;
