I'm proud to announce that MJSON v0.4 has been released!

MJSON is Maciel's JSON parser, a small light-weight library that
handles documents written in the JSON markup language. It's written in
ISO C, which means that it may run wherever there is a C compiler.

It's still in alpha stage but at the moment it is capable of parsing
every JSON example present in www.json.org.

This new release features, along with some bug fixes, a new SAX-like
parser - json_saxy_parser() -  which allows to handle JSON documents
sequentially. In order to showcase the new parser, a small test
application, jsonindent, was also released. jsonindent is a small JSON
pretty printer written completely in ISO C and relying on MJSON's
json_saxy_parser() to format JSON documents.


MJSON and jsonindent can be found at:
http://sourceforge.net/projects/mjson

you can put whole functions in a json object if you like. So in short
yes just make a new Date() object within you JSON object.

Does this mean that Date objects created using new Date() can be
directly mapped to Java Objects? Can the date object created this way
be formatted into different date time formats?
please let me know
Thanks

Hi,

JSON does not support either datetime object or function object. Look at BNF on
http://www.json.org/ how "value" is defined.
It contains, ["string", "number", "object", "array", "true", "false", "null"].
On this definition "object" is a JSON object (where you can find the definition
above "value"), not a Javascript object.

Although you can freely add something like new Date(2007, 7, 12, 0, 0, 0) or
function(x,y) {return x+y;}, this makes that document a Javascript document
(where you can eval), not JSON document.

You can write any date data as a string in a JSON document, then if you are
using Java, C# or Javascript (or any other), you can use that language's,
DateTime functions to convert.

Basically Dates are encoded as ISO 8601 strings by default (but this
can be customized), and a "hook" or callback function allows you to
deserialize them (or any other node for that matter) during parseJSON.

Functions are strictly not allowed in JSON as they are potentially
meaningless to other languages as well as a potential security risks.

There has also be some debates about Dates a couple of times before,
which resulted in the above solution. Check out some of these threads
for more info:

The json.js reference implementation now produces date strings in the
ISO Z format, in anticipation of the addition of
Date.prototype.toISOString to ECMAScript.

http://www.JSON.org/json.js

Hi,
Now I built some mashup using JSON. Sometimes, I want to block the
script to be executed. I want to remove the script dynamically added
to prevent it from execution. Is there some way for me to do this ?

Or, if you  have other idea to implement this function, coul d you
share it with me ?

Thanks a lot.

I changed the way that json.js calls the hasOwnProperty method. A
design flaw in JavaScript causes hasOwnProperty to fail when an object
contains a property called "hasOwnProperty".

Hi,I have difficulties to parse this json
{depth1:{depth2:{depth3:'content'}}}
how to get the 'content'?? using ajax?

well you don't get "content" using ajax. You get "content" using
javascript...
if that json string was assigned to a variable foo...
var foo = {depth1 : { depth2 : {depth3 : 'content'}}};
and you set...
var foo1 = foo.depth1.depth2.depth3;
then the value of foo1 would be 'content;

That's not valid JSON, for two reasons:

1) Key names are strings, and must be quoted as such.
2) Strings must be quoted with double quotes, not single quotes.

See http://json.org/ for the JSON specification.

I will use this for my AJAX. Using responsetext properties from XHR.
:) ok,then how to parse, {"depth1":{"depth2":{"depth3":"content"}}} ??
btw, thank you for your response. I am glad, I am on the right place.

This should help:
	 eval("var responsejson = (" + responsetext + ");");
	 alert(responsejson['depth1']['depth2']['depth3'];

Ugh, don't do that.  Apart from screwing with the scope of
responsejson, it also causes a security problem, and it's overkill.
If you must use eval, do it this way:

var responsejson = eval( "(" + o.responseText + ")" );

That won't take away the security problems with eval, but it will make
sure that responsejson is in current scope.

Hello folks,



First, I'm relatively new to working with JSON so please bear with me.
Here's the situation:



I am attempting to use multiple callbacks all from the same provider, but of
course, overlapped onclick events steal each other's scopes.the removeChild
function wouldn't have yet had a chance to complete before the next onclick
event initiates so it "steals" the contents of the callback function.



To make sense of what I am talking about, imagine using many JSON Flickr
callbacks in rapid succession with the hopes of having the outputs appear in
different divisions on one page. To see what I am talking about, have a peek
at a development page I am working on & attempt to click the search icons
beside references by Archer between 1950 & 1958 in rapid succession on
http://canadianarachnology.dyndns.org/data/canada_spiders/AllReferences2.asp
. Note that the JSON provider (not Flickr of course) is still working on his
JSON-generating function, so please stick to those references to fire the
onclick call.other onclicks to call the provider may return XML instead of
JSON. Note also that the above URL will return a 404 once I figure out how
best to do this. I guess what I'm after is a method to alert the user to
wait for a callback to complete before he/she attempts to initiate a second
one because the removeChild wouldn't have yet had a chance to clear the
callback function from their browser page's head section. Is this at all
possible?



Any help would be most appreciated,

The toJSONString methods can now take an optional whitelist parameter,
an array of strings. It is used to select the properties that will be
included in the JSON text.

http://www.json.org/json.js

The JSON.org page is now available in Dutch.

http://json.org/json-nl.html

Hi,

I have a JSON object which has a strcture like this :

{ "MainData":
	 {

		 "Company":
			 {
			 "Name":"ABC Ltd",
			 "Address":"<address>"
			 },
		 "Data":
			 {
				 "001":
				 {
					 "Name": "Test",
					 "Age":"45"
				 },
				 "002":
				 {
					 "Name" : "Sample",
					 "Age":"35"
				 }
			 }
		 }
}

In this, "001", "002" are emloyee numbers.
Now assume the employee number is passed from an another function as
an input. (Let it be EmpNo)

Now, I need to check if the passed in employee number is present in
the JSON structure and accordingly retreive the data.

I need to use the javascript for this.
If I try to say

	 MainData.Company.Data.eval(EmpNo);

this works fine if the EmpNo is 001 or 002.
But if the EmpNo is 135, which is not present in the JSON output, it
throws an error.

How I can check that the input EmpNo is present in the JSON
structure.(This needs to be done in javascript)
Any help would be greatly appreciated.

Thanks in advance for the answer.

avoid using eval.  Just use the "in" operator"

if(EmpNo in MainData.Company.Data)

in checks for the existence of a key.
