I have a JSON object that doesn't have a key for the three values given (each is an array) and I want to parse through them. How might I do this in JQuery?

[
    {
        "cid": "3",
        "pid": "0",
        "nid": "12",

Answer 1

Your JSON is not valid.

Once you create a valid JSON string, parsing it is very simple.

Use the following steps:

1. remove the commas after the last property of each object
2. remove the newlines
3. wrap the JSON text in single quotes
4. call jQuery.parseJSON() on the text

Here's a working fiddle.

It does something like this:

var jsonText = '[ { "cid": "3", "pid": "0", "nid"...} ]';
var jo = $.parseJSON(jsonText);

If you have the JSON in string form, you can use JSON.parse^[MDN] to get it in object form, and then do with it what you need to.

Modern browsers have this function natively - no jQuery necessary - but you can also include it yourself from one of these locations:
