我從控制器至極這個數組傳遞給我的樹枝在那裏我執行下面的代碼，它解析爲一個JS數組：推在爵士看不到風度的陣列正常工作

{% for flight in flights%} 
        var $FlightSegment = new Array(); 
        $flight.push({ 
         key:"{{ flight.key }}", 
         DepartureDate:"{{flight.DepartureDate}}", 
         ArrivalDate:"{{flight.ArrivalDate}}", 
         Amount:"{{flight.BaseFareAmtInclTax}}", 

        }); 
        {% for ReturnFlightSegmentDetails in flight.ReturnFlightSegmentDetails %} 
          $FlightSegment.push({ 
           LFID :"{{ReturnFlightSegmentDetails.LFID}}", 
           DepartureDate:"{{ReturnFlightSegmentDetails.DepartureDate}}", 
           ArrivalDate:"{{ReturnFlightSegmentDetails.BaseFareAmtInclTax}}", 
           Class:"{{ReturnFlightSegmentDetails.FareTypeName}}", 
          }); 
         {% endfor %} 
         console.info($FlightSegment); 
        $flight.push({ 
         ReturnFlightSegmentDetails :$FlightSegment, 
        }); 
       {% endfor %}

問題是，$ flight.length返回4而不是2：/的ReturnFlightSegmentDetails被認爲是像一個對象，而不是成爲一個飛行中的attibut：/

那麼你是單獨推入清單。 – Pointy

此外，建議讓小枝用'json_encode'做這件事似乎是一個不錯的主意。 – Pointy

對不起，但我不明白哪裏是錯誤：/我在全球範圍內第二次推！ oO'我將排序數據，所以這就是爲什麼我選擇解析到一個js數組，因爲它會更容易，我想然後有一個字符串與json_encode – fbh

你需要以不同的方式打造「飛行」對象; 「$ FlightSegment」變量真的不需要。

{% for flight in flights%} 
    $flight.push({ 
     key: "{{ flight.key }}", 
     DepartureDate: "{{flight.DepartureDate}}", 
     ArrivalDate: "{{flight.ArrivalDate}}", 
     Amount: "{{flight.BaseFareAmtInclTax}}", 
     ReturnFlighSegmentDetails: [ 
      {% for ReturnFlightSegmentDetails in flight.ReturnFlightSegmentDetails %} 
      { 
       LFID :"{{ReturnFlightSegmentDetails.LFID}}", 
       DepartureDate:"{{ReturnFlightSegmentDetails.DepartureDate}}", 
       ArrivalDate:"{{ReturnFlightSegmentDetails.BaseFareAmtInclTax}}", 
       Class:"{{ReturnFlightSegmentDetails.FareTypeName}}" 
       } 
       {% if not loop.last } , {% endif } 
      {% endfor %} 
     ] 
     }); 
{% endfor %}

你做了我的一天，我很感激謝謝:)但我不知道'不會得到這個{％如果不是loop.last}，{％endif}它意味着什麼？ – fbh

@fbh它是在那個子陣列中的對象之間添加必要的逗號*。當你在最後一次迭代時，你不需要一個逗號，因爲這對老版本的IE來說是一個問題。「循環」變量是twig'for'循環的一個特性;它會自動提供。 – Pointy
