I'd try to cut down the problem. First make sure, the JSON is valid and looks the way you expect. Don't use jQuery at this point. Call the symfony controller in your browser directly. Then check the json. http://jsonviewer.stack.hu might be of use.

Once you verfified that the JSON itself is valid and contains what you need, we can look at the jQuery part. Then we'd need the code and the errors you get.

当我从Controller返回JSOn时，我做错了。现在还可以
