json已发送到视图，但无法从其获取id

请帮我解决这个问题。我对node和json都是新手。 一定是出了什么大问题

extends layout

block content
  h3 Trips selection #{trips}  //shows following json in the view
  form.form-horizontal(id="Findtrips", accept-charset="UTF-8", 
  action="#", method="post" enctype="multipart/form-data")
    each trip in trips
      p #{trip.tripId} //doesnt pusblish anything

{trips}给出了以下内容：

{
  "onwardTrips": [{
    "tripId": "1285170",
    "fromCity": "Singapore",
    "toCity": "Malacca",
    "operatorCode": "SA",
    "operatorName": "Starmart Express",
    "departTime": "2014-01-20 20:00:00.0",
    "busType": "Executive",
    "pickupPointDetails": [{
      "pickupPointId": "78",
      "departureTime": "2014-01-20 20:00:00.0",
      "pickupPointName": "Golden Mile Tower, Beach Road"
    }],
    "dropoffPointDetails": [{
      "dropOffPointName": "Melaka Sentral",
      "dropOffPointId": "1285170"
    }],
    "fareDetails": {
      "adultFare": "65.0"
    }
  }, 
  {
    "tripId": "1285254",
    "fromCity": "Singapore",
    "toCity": "Malacca",
    "operatorCode": "SA",
    "operatorName": "Starmart Express",
    "departTime": "2014-01-20 23:00:00.0",
    "busType": "Executive",
    "pickupPointDetails": [{
      "pickupPointId": "78",
      "departureTime": "2014-01-20 23:00:00.0",
      "pickupPointName": "Golden Mile Tower, Beach Road"
    }],
    "dropoffPointDetails": [{
      "dropOffPointName": "Melaka Sentral",
      "dropOffPointId": "1285254"
    }],
    "fareDetails": {
      "adultFare": "65.0"
    }
  }],
  "errorCode": 0
}

server.js

getTrips: function getTrips(req, res, next){
     var url = 'CTB-WS/rest/trips?from='+ req.tripinfo.fromCityId + '&to=' + req.tripinfo.toCityId + '&depart-date=' + req.tripinfo.departDate+ '&pax=1';
     console.log(url);
     rest.get(url).on('complete', function(trips) {
      if (trips instanceof Error) {
        console.log('Error:', trips.message);
        } else {        
          console.log('trips'+ JSON.stringify(trips));  
          req.trips = JSON.stringify(trips);
          next();

        }
    });
  },

  sendTrips: function sendTrips(req, res, next){
    res.render('trips', {trips : req.trips});
  }

在jsonactually Javascript对象中，trips不是数组。而是trips.forwardTrips是一个数组。 请把每件衣服换成翡翠色

if trips.onwardTrips
  each trip in trips.onwardTrips
    p #{trip.tripId}

通过以下方式解决它。我得到trips.tripId现在我想得到trip内部的数组，即dropoffPointDetails

 getTrips: function getTrips(req, res, next){
     var url = 'CTB-WS/rest/trips?from='+ req.tripinfo.fromCityId + '&to=' + req.tripinfo.toCityId + '&depart-date=' + req.tripinfo.departDate+ '&pax=1';
     console.log(url);
     rest.get(url).on('complete', function(trips) {
      if (trips instanceof Error) {
        console.log('Error:', trips.message);
        } else {        
          console.log('trips'+ JSON.stringify(trips));  
          trips = trips || [];
          req.trips = trips['onwardTrips'];
          next();
        }
    });
  },

  sendTrips: function sendTrips(req, res, next){
    //res.render('trips', {trips : req.trips});
   res.render('trips', { trips: req.trips});

  }

请正确地编排你的问题。Jade对空格敏感。如果您无法找出标记来设置问题的格式，可能对空格敏感的模板语言不是您的最佳选择。对不起，是的，我已设置了格式。我遇到了错误。TypeError:/home/jyoti/catchthatbus/views/trips.jade:6 4 | h3 trips selection{trips}5 | form.form horizontalid=Findtrips，accept charset=UTF-8，action=，method=post enctype=multipart/form data>6 | trips.forwardTrips 7{trip.fromCity}8 | 9 |无法读取未定义的属性“length”确保行程具有ForwardTrips数组。从错误中可以看出，ForwardTrips是未定义的。我已经更新了答案，以检查对象中是否存在错误。
