ASP.NET与json对象互转 有大用

 <script>
         //script里简单的解析json
        var json = '{"name": "学生","info": [{ "count": "1", "stuname": "张三 ", "stuNO": "123" }, { "count": "2", "stuname": "里斯 ", "stuNO": "456" }] }'         
        var obj = JSON.parse(json);
        alert(obj.name);
         alert(obj.info[0].count);//按顺序弹出消息弹框
          alert(obj.info[1].stuname);
    </script>
