How to access JSON object with Jquery (WikiAPI)

Question

I am getting the below json return from wiki:

{
"query": {
    "pages": {
        "1514": {
            "pageid": 1514,
            "ns": 0,
            "title": "exampletitle",
            "extract": "Example extract"
        }
    }
}
}

How can I access the "extract" value from this json? I will not know the page id (1514) and can't simply do a json.query.pages.1514.extract;

(anyway .1514 will not work)

Thank you!

if you don't know page number, how do you suppose to get data in case there are 20 pages in pages object? Or you need ALL of them and looking for a way to iterate it as array? — Tommi

You can iterate over the pages object to access its members

for(var key in json.query.pages){
    if(json.query.pages.hasOwnProperty(key)){
        console.log(json.query.pages[key].extract);
    }
 }

json.query.pages['1514'].extract should work

Ah! However, I won't know that it's 1514 unless I can access the pageid

use JSON.parse()

ex:

var [your_parsed_JSON] = JSON.parse([your_JSON_variable])

heres a similar stackoverflow question with more detail/examples:

Parse JSON in JavaScript?

EDIT: actually it appears you are trying to access the contents of a container that you do not know. That's like trying to find the "lost treasure" without knowing where it is.

Reorganize your data structure.

It's the wikimedia API though, I don't have control over the data returned!
