* CREDITS:

|
* Thanks to Kris Zyp from SitePen for contributing his source for
|
|
* a standalone port of JSONQuery (from the dojox.json.query module).
|
|
*
|
|
* OVERVIEW:
|
|
* JSONQuery.js is a standalone port of the dojox.json.query module. It is intended as
|
|
* a dropin solution with zero dependencies. JSONQuery is intended to succeed and improve upon
|
|
* the JSONPath api (http://goessner.net/articles/JsonPath/) which offers rich powerful
|
|
* querying capabilities similar to those of XQuery.
|
|
*
|
|
* EXAMPLES / USAGE:
|
|
* see http://www.sitepen.com/blog/2008/07/16/jsonquery-data-querying-beyond-jsonpath/
|
|
*
|
|
* *Ripped from original source.
|
|
* JSONQuery(queryString,object)
|
|
and
|
|
JSONQuery(queryString)(object)
|
|
always return identical results. The first one immediately evaluates, the second one returns a
|
|
function that then evaluates the object.
|
|
|
|
example:
|
|
JSONQuery("foo",{foo:"bar"})
|
|
This will return "bar".
|
|
|
|
example:
|
|
evaluator = JSONQuery("?foo='bar'&rating>3");
|
|
This creates a function that finds all the objects in an array with a property
|
|
foo that is equals to "bar" and with a rating property with a value greater
|
|
than 3.
|
|
evaluator([{foo:"bar",rating:4},{foo:"baz",rating:2}])
|
|
This returns:
|
|
{foo:"bar",rating:4}
|
|
|
|
example:
|
|
evaluator = JSONQuery("$[?price<15.00][\rating][0:10]");
|
|
This finds objects in array with a price less than 15.00 and sorts then
|
|
by rating, highest rated first, and returns the first ten items in from this
|
|
filtered and sorted list.
|
|
|
|
|
|
example:
|
|
var data = {customers:[
|
|
{name:"Susan", purchases:29},
|
|
{name:"Kim", purchases:150},
|
|
{name:"Jake", purchases:27}
|
|
]};
|
|
|
|
var results = json.JSONQuery("$.customers[?purchases > 21 & name='Jake'][\\purchases]",data);
|
|
results
|
|
|
|
returns customers sorted by higest number of purchases to lowest.

// Performs a JSONQuery on the provided object and returns the results.

// description:
|
|
// JSONQuery provides a comprehensive set of data querying tools including filtering,
|
|
// recursive search, sorting, mapping, range selection, and powerful expressions with
|
|
// wildcard string comparisons and various operators. JSONQuery generally supersets
|
|
// JSONPath and provides syntax that matches and behaves like JavaScript where
|
|
// possible.
|
|
//
|
|
// JSONQuery evaluations begin with the provided object, which can referenced with
|
|
// $. From
|
|
// the starting object, various operators can be successively applied, each operating
|
|
// on the result of the last operation.
|
|
//
|
|
// Supported Operators:
|
|
// --------------------
|
|
// * .property - This will return the provided property of the object, behaving exactly
|
|
// like JavaScript.
|
|
// * [expression] - This returns the property name/index defined by the evaluation of
|
|
// the provided expression, behaving exactly like JavaScript.
|
|
// * [?expression] - This will perform a filter operation on an array, returning all the
|
|
// items in an array that match the provided expression. This operator does not
|
|
// need to be in brackets, you can simply use ?expression, but since it does not
|
|
// have any containment, no operators can be used afterwards when used
|
|
// without brackets.
|
|
// * [^?expression] - This will perform a distinct filter operation on an array. This behaves
|
|
// as [?expression] except that it will remove any duplicate values/objects from the
|
|
// result set.
|
|
// * [/expression], [\expression], [/expression, /expression] - This performs a sort
|
|
// operation on an array, with sort based on the provide expression. Multiple comma delimited sort
|
|
// expressions can be provided for multiple sort orders (first being highest priority). /
|
|
// indicates ascending order and \ indicates descending order
|
|
// * [=expression] - This performs a map operation on an array, creating a new array
|
|
// with each item being the evaluation of the expression for each item in the source array.
|
|
// * [start:end:step] - This performs an array slice/range operation, returning the elements
|
|
// from the optional start index to the optional end index, stepping by the optional step number.
|
|
// * [expr,expr] - This a union operator, returning an array of all the property/index values from
|
|
// the evaluation of the comma delimited expressions.
|
|
// * .* or [*] - This returns the values of all the properties of the current object.
|
|
// * $ - This is the root object, If a JSONQuery expression does not being with a $,
|
|
// it will be auto-inserted at the beginning.
|
|
// * @ - This is the current object in filter, sort, and map expressions. This is generally
|
|
// not necessary, names are auto-converted to property references of the current object
|
|
// in expressions.
|
|
// * ..property - Performs a recursive search for the given property name, returning
|
|
// an array of all values with such a property name in the current object and any subobjects
|
|
// * expr = expr - Performs a comparison (like JS's ==). When comparing to
|
|
// a string, the comparison string may contain wildcards * (matches any number of
|
|
// characters) and ? (matches any single character).
|
|
// * expr ~ expr - Performs a string comparison with case insensitivity.
|
|
// * ..[?expression] - This will perform a deep search filter operation on all the objects and
|
|
// subobjects of the current data. Rather than only searching an array, this will search
|
|
// property values, arrays, and their children.
|
|
// * $1,$2,$3, etc. - These are references to extra parameters passed to the query
|
|
// function or the evaluator function.
|
|
// * +, -, /, *, &, |, %, (, ), <, >, <=, >=, != - These operators behave just as they do
|
|
// in JavaScript.
|
|
//
|
|
//
|
|
//
|
|
// | dojox.json.query(queryString,object)
|
|
// and
|
|
// | dojox.json.query(queryString)(object)

|
// always return identical results. The first one immediately evaluates, the second one returns a

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 object holding the key.
|
|
|
|
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;
|
