我需要查看每个酒店密钥并进入房价以检索一些信息，我怎样才能在JavaScript中使用这个JSON获取它们的值：

我尝试使用for (var key in data)，其中data是来自AJAX的JSON响应。
答案 0 :(得分：0)
这是一个数组。您应该使用正常的for循环进行迭代，例如
for(var i = 0; i < data.length;i++) {
var rooms = data[i].hotel.rooms
for(var j = 0; j < rooms.length; j++) {
var rates = rooms.rates .. //do something with rates, it's also an array
}
}
答案 1 :(得分：0)
每次看到[]时，使用每个循环，字符串中的第一个字符是括号，所以我们在每个案例中选择一个孩子＆＃34; hotel＆＃34;使用点符号v.hotel，v。酒店不会以括号开头，所以我们不需要循环，我们在json对象中向下，直到我们到达rates键，我们看到另一个braket所以我们循环并在我们的例子中选择子元素rateKey
var obj =[
{
"auditData": {
"processTime": "1545",
"timestamp": "2016-04-08 04:33:17.145",
"requestHost": "66.226.74.194",
"serverId": "sa37AUX3ROLBLIS.env",

"release": "2cb1bad878d2195c9b508e2007ef96616007dacb",
"internal": "bz66k2etuxrt5q5h2zyf3jf6|MX|03|HA|1|3|0|1|3|N|||||||||1"
},...];
$.each(obj, function(i, v) {
$.each(v.hotel.rooms, function(i1, v1) {
$.each(v1.rates, function(i2, v2) {
console.log(v2.rateKey);
});
})
});

使用Json对象。 如果假设值存储在JsonObject中。
您可能想要检索一些值。 例如： - “code”：87399， “名字”：“总理”， “categoryCode”：“3EST”， “categoryName”：“3 ESTRELLAS”， “destinationCode”：“MDF”， “destinationName”：“Ciudad de Mexico”，
$(JsonObject).each(function(){
$(this).hotel.code;
$(this).hotel.name;
})
