我有一个非常简单的问题，但我没有编程经验。我确定有一个简单的解决方案我的问题。我想从谷歌方向api收集一些信息，但不是全部。问题是如何保持订单，因为在步骤数组中，信息提供者在步行和过境模式中有所偏离：（
我有一个JSON对象。

如何遍历对象获取所有必要信息并保持顺序。我试图建立一个2个对象。所以我在walking.key或transit.key中保存订单。好。但是在使用for循环之后如何以正确的顺序从两个对象中按顺序获取所有信息。我的第一步是否有任何意义？还是有更好的方法？
var walking = {
distance : [],
duration : [],
html_instructions: [],
key : []
};
var transit = {
distance : [],
duration : [],
html_instructions: [],
busStopName : [],
departureTime : [],
vehicle : [],
number : [],
route : [],
headsign :[],
key: []
};
for (key in myResult) {
if ( (typeof(myResult[key]["travel_mode"])!=="undefined") && myResult[key]["travel_mode"]=== "WALKING") {
walking.distance.push(myResult[key]["distance"]["text"]);
walking.duration.push(myResult[key]["duration"]["text"]);
walking.duration.push(myResult[key]["html_instructions"]);
walking.key.push(myResult[key]);
}
if ( (typeof(myResult[key]["travel_mode"])!=="undefined") && myResult[key]["travel_mode"]=== "TRANSIT") {
transit.headsign.push(myResult[key]["transit_details"]["headsign"]);
transit.busStopName.push(myResult[key]["transit_details"]["departure_stop"]["name"]);
transit.departureTime.push(myResult[key]["transit_details"]["departure_time"]["text"]);
transit.distance.push(myResult[key]["distance"]["text"]);
transit.duration.push(myResult[key]["duration"]["text"]);
transit.vehicle.push(myResult[key]["transit_details"]["line"]["vehicle"]["name"]);
transit.number.push(myResult[key]["transit_details"]["line"]["short_name"]);
transit.route.push(myResult[key]["transit_details"]["line"]["name"]);
transit.key.push(myResult[key]);
}
}
