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>
<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>
{"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?"}]}}
</body>
