[解决办法]
eval（内容）
[解决办法]
你可以调试一下js啊
那设个断点 看什么类型
[解决办法]
你应该能得到children 里面的之把
实在不行用str.split(",")切一下
[解决办法]
我用的是org.json 测试了下没问题的

Java code
        JSONArray arr=new JSONArray(jsonStr);        JSONObject obj=null;        for(int i=0,l=arr.length();i<l;i++){            obj=arr.getJSONObject(i);            System.out.println(obj.get("Name"));        }
[解决办法]
aa[i].children[i].key   2个循环就能实现。
