how to add/modify Json data(file) using javascript/jquery/ajax?

Hi,

Is there a way to modify the json data using javascript/jquery/ajax?

Q1)
I need to add additional properties to the json data.

ex)

[
{ 'text': 'john doe', 'age':'29', 'id':'123', 'uri': 'xxxxx'},
{ 'text': 'jane doe', 'age':'22', 'id':'122', 'uri': 'xxxxx'},
{ 'text': 'joe doe', 'age':'12', 'id':'121', 'uri': 'xxxxx'}
]

Open in new window

I need to add 'parent':'xxxx'

I get the json data from the web service call.

can you show me an example or tutorial how I can do this please?
I must be looking at wrong place and can't find any examples.
Thanks.

If you just wan't to add the value to one of the records, then something like this:

var json = [
{ 'text': 'john doe', 'age':'29', 'id':'123', 'uri': 'xxxxx'},
{ 'text': 'jane doe', 'age':'22', 'id':'122', 'uri': 'xxxxx'},
{ 'text': 'joe doe', 'age':'12', 'id':'121', 'uri': 'xxxxx'}
]

json[1].parent = 'xxxx';

Open in new window

If you want to loop through all the records, then like this:

$(json).each(function(i,elem) {
	elem.parent = 'xxxx';
});

Open in new window

$(json).each(function(i,elem) {

are i and elem the builtin(??) property name or did you make them up?

also is json variable a json object or array?
I get confused on that.
Thanks.
