Encoding Javascript Object to Json string

Question

I want to encode a Javascript object into a JSON string and I am having considerable difficulties.

The Object looks something like this

new_tweets[k]['tweet_id'] = 98745521; new_tweets[k]['user_id'] = 54875;        new_tweets[k]['data']['in_reply_to_screen_name'] = "other_user"; new_tweets[k]['data']['text'] = "tweet text"; 

I want to get this into a JSON string to put it into an ajax request.

{'k':{'tweet_id':98745521,'user_id':54875, 'data':{...}}} 

you get the picture. No matter what I do, it just doesn't work. All the JSON encoders like json2 and such produce

[] 

Well, that does not help me. Basically I would like to have something like the php encodejson function.

Unless the variable k is defined, that's probably what's causing your trouble. Something like this will do what you want:

var new_tweets = { };  new_tweets.k = { };  new_tweets.k.tweet_id = 98745521; new_tweets.k.user_id = 54875;  new_tweets.k.data = { };  new_tweets.k.data.in_reply_to_screen_name = 'other_user'; new_tweets.k.data.text = 'tweet text';  // Will create the JSON string you're looking for. var json = JSON.stringify(new_tweets); 

You can also do it all at once:

var new_tweets = {   k: {     tweet_id: 98745521,     user_id: 54875,     data: {       in_reply_to_screen_name: 'other_user',       text: 'tweet_text'     }   } }
