How to read json

I have following JSON object.

{"feed":[
    {"news":
      {"adopted_from":null,"user_id":null,"description":"this is test","开发者_开发问答id":2}
   },
   {"news":
     {"adopted_from":null,"user_id":null,"description":"like unlike done","id":1}
    }
]}

I want to retrieve the id of news. I tried in many different ways (e.g. feed[0].news.id, feed.news.id, feed[[0].news.id]) but could not access the value. Can anyone help me how can I access it using JavaScript?

I copied and pasted your JSON from above and tried the following and it works just fine:

    var data = {"feed":[{"news":{"adopted_from":null,"user_id":null,"description":"this is test","id":2}},{"news":{"adopted_from":null,"user_id":null,"description":"like unlike done","id":1}}]};
    // alert the first news id
    alert(data.feed[0].news.id);

It gets the id from the first news object from the array as intended.

this works for me:

var f = {"feed":[{"news":{"adopted_from":null,"user_id":null,"description":"this is test","id":2}},{"news":{"adopted_from":null,"user_id":null,"description":"like unlike done","id":1}}]}
alert( f.feed[0].news.id )

var feed = json_decode(yourData)
for(var counter in feed) {
    console.log(feed[counter].news.id);
}
