将Javascript对象编码为Json字符串 [英] Encoding Javascript Object to Json string
问题描述
我想将Javascript对象编码为JSON字符串,我遇到了相当大的困难。
I want to encode a Javascript object into a JSON string and I am having considerable difficulties.
对象看起来像这样
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";
我想把它变成一个JSON字符串,把它放到一个ajax请求中。
I want to get this into a JSON string to put it into an ajax request.
{'k':{'tweet_id':98745521,'user_id':54875, 'data':{...}}}
你得到的照片。不管我做什么,它都行不通。所有JSON编码器如json2等产品
you get the picture. No matter what I do, it just doesn't work. All the JSON encoders like json2 and such produce
[]
嗯,这对我没有帮助。基本上我想要像php encodejson
这样的功能。
Well, that does not help me. Basically I would like to have something like the php encodejson
function.
推荐答案
除非定义了变量 k
,否则这可能是导致你的麻烦。这样的事情会做你想要的:
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);
您也可以一次性完成所有操作:
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'
}
}
}
