js 操作json数据

今天的收获了以下知识，在这里在感谢【人生如梦】



<script type="text/javascript">
function showJSON() {
var user =
{
"username":"liang",
"age":20,
"info": { "tel": "tel", "phone": "phone"},
"address": [{"city":"city","postcode":"postcode"} ]
}
alert(user.username);
alert(user.age);
alert(user.info.tel);
alert(user.address[0].city);
alert(user.address[0].postcode);
}

</script>
