这种json对象里的多条数据如何进行操作呢？？？？？？？？？？
{
"basketFee":{"fee":0.0,"total":34.0},
"cart":{
"17":{"amount":18,"categoryName":"经典主食","id":17,"name":"tes1t商品","price":0.0,"subtotal":0.0},
"13":{"amount":34,"categoryName":"正餐","id":13,"name":"商品名称3","price":1.0,"subtotal":34.0},
"18":{"amount":14,"categoryName":"经典主食","id":18,"name":"test2商品","price":0.0,"subtotal":0.0}
}
}
问题就在于cart下面的多条记录如何获取呢，试了很多办法都行不通，我是把map对象转成的json，所以会出现cart下的数字对应记录的情况，求各位牛人指教啊！！！！！！！！！！折腾了好半天了

- JScript code
var data = {
"basketFee":{"fee":0.0,"total":34.0},
"cart":{
"17":{"amount":18,"categoryName":"经典主食","id":17,"name":"tes1t商品","price":0.0,"subtotal":0.0},
"13":{"amount":34,"categoryName":"正餐","id":13,"name":"商品名称3","price":1.0,"subtotal":34.0},
"18":{"amount":14,"categoryName":"经典主食","id":18,"name":"test2商品","price":0.0,"subtotal":0.0}
}
}
for(var name in data.cart)
{
alert(name + "=" + data.cart[name]);//不确定的属性使用in表达式
}
------解决方案--------------------
- HTML code
<!DOCTYPE HTML>
<html>
<head>
<meta charset="gb2312" />
<title></title>
</head>
<body>
<script>
var obj = {
"basketFee":{"fee":0.0,"total":34.0},
"cart":{
"17":{"amount":18,"categoryName":"经典主食","id":17,"name":"tes1t商品","price":0.0,"subtotal":0.0},
"13":{"amount":34,"categoryName":"正餐","id":13,"name":"商品名称3","price":1.0,"subtotal":34.0},
"18":{"amount":14,"categoryName":"经典主食","id":18,"name":"test2商品","price":0.0,"subtotal":0.0}
}
};
alert( obj.cart[17].categoryName )
</script>
</body>
</html>

+1本来就是json的对象了，当然可以直接点过去用。
