How to parse JSON data, using javascript

Question

Can someone please show me how I can get my JSON data and use it in javascript?

My data looks like this...

[{
    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 501",
    "2": "Parameter 501",
    "setting_value": "true",
    "3": "true"
}, {
    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 502",
    "2": "Parameter 502",
    "setting_value": "true",
    "3": "true"
}, {
    "id": "1",
    "0": "1",
    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 503",

    "1": "CONFIG 1",
    "setting_name": "Parameter 505",

    "filename": "CONFIG 1",
    "1": "CONFIG 1",
    "setting_name": "Parameter 506",

}, {
    "id": "2",
    "0": "2",

}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 505",

}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 506",
    "2": "Parameter 506",
    "setting_value": "17",
    "3": "17"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 507",
    "2": "Parameter 507",
    "setting_value": "3",
    "3": "3"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 508",
    "2": "Parameter 508",
    "setting_value": "18",
    "3": "18"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 509",
    "2": "Parameter 509",
    "setting_value": "19",
    "3": "19"
}, {
    "id": "2",
    "0": "2",
    "filename": "CONFIG 2",
    "1": "CONFIG 2",
    "setting_name": "Parameter 501",
    "2": "Parameter 501",
    "setting_value": "false",
    "3": "false"
}, false]

Basically I have four fields... id, filename, setting_name and setting_value.

I need to know how I can get this and convert it into a javascript array, so that I may use it withing my logic. N

@vol7ron Looks like an accidental double-post. This one came first — Phil

@Phil: I just like to close them both, for the sheer fact that it's a double and the question is horrible to look at. — vol7ron

Your syntax for JSON data is incorrect. Json data is enclosed within {} and not []. Still for parsing JSON data use json2.js library from the link.

https://github.com/douglascrockford/JSON-js/blob/master/json2.js

and use;

var myObject = JSON.parse(myJSONtext, reviver);

The link you provide contradicts your statement that JSON data is only objects: "any JavaScript value, usually an object or array."
