json是种常用数据传输格式，js怎么解析json格式的数据呢，请参阅下面的代码：

[html] view plaincopy

<html>

    <head>

        <script type="text/javascript">

            var data = '{"return_code":0,"return_message":"success","data":{"data":[{"id":"1","question":"公主令牌在哪交？"},{"id":"2","question":"公主护使有什么用？"},{"id":"3","question":"角斗场在哪？"},{"id":"4","question":"北部断层在哪？"},{"id":"5","question":"欢乐令有什么用？"},{"id":"6","question":"令牌积分有什么用？"},{"id":"7","question":"南部断层在哪？"},{"id":"8","question":"大妖魔令牌交给谁？"},{"id":"9","question":"神工坊在哪？"},{"id":"10","question":"警戒妖珠有什么用？"}]}}';



            function ShowData(){



                var obj = eval("("+data+")");



                alert("return_code:"+obj["return_code"]);

                alert("return_message:"+obj["return_message"]);

                alert("第一个问题id：" + obj["data"]["data"][0]["id"]);

                alert("第一个内容id：" + obj["data"]["data"][0]["question"]);

            }



        </script>

    </head>



<body onload="ShowData();">

    {"return_code":0,"return_message":"success","data":{"data":[{"id":"1","question":"公主令牌在哪交？"},{"id":"2","question":"公主护使有什么用？"},{"id":"3","question":"角斗场在哪？"},{"id":"4","question":"北部断层在哪？"},{"id":"5","question":"欢乐令有什么用？"},{"id":"6","question":"令牌积分有什么用？"},{"id":"7","question":"南部断层在哪？"},{"id":"8","question":"大妖魔令牌交给谁？"},{"id":"9","question":"神工坊在哪？"},{"id":"10","question":"警戒妖珠有什么用？"}]}}
