Question

我是离子的新手，我希望能够扩展一个简单的json数据集以包含数组中的列表：我的json文件如下所示：

    .factory('Purchase_orders', function($filter) { 
  var orders = [
    {
      id: 1,
      OrderTypeCoded: 'Order',

  return {
    all: function() {
      return orders;
    },
    groupByDate: function() {
      var group = {};
      for (var i = 0; i < orders.length; i++) {
        var dateObj = new Date(orders[i].date);
        var date = $filter('date')(dateObj, 'dd-MM-yyyy');

        orders[i].time = $filter('date')(dateObj, 'HH:mm');

        if (angular.isDefined(group[date])) {

          group[date].push(orders[i]);
        } else {
          // add group
          group[date] = [
            orders[i]
          ]
        }
      }

      return group;
    },
    remove: function(orderId) {
      orders.splice(orders.indexOf(orderId), 1);
    },
    get: function(orderId) {
      for (var i = 0; i < orders.length; i++) {
        if (orders[i].id === parseInt(orderId)) {
          return orders[i];
        }
      }
      return null;
    }
  };
})

所以我已经能够使用重复返回乐队列表并传递乐队ID以显示各个乐队的详细信息。

此时我可以显示数据（标题），例如（OrderNumber，Identifier，Name等）。

我需要显示json（OrderLine）的详细信息，例如：（LineNumber，StandardProductCode等）。

要访问标题数据，请执行以下操作：

<h5 class="padding-left">FORNECEDOR</h5>
<ion-item class="item item-text-wrap">
    <p> {{ order.Identifier }}
        <br>{{ order.Name }}
        <br> {{ order.Street }} - {{ order.City }}
        <br> {{ order.PostalCode }}
    </p>
</ion-item>

但我无法显示详细数据（OrderLine.StandardProductCode）。我错过了一些功能吗？

从它的外观来看。我认为你需要的是重复，因为如果你可以访问主键，你也可以访问订单键，但订单键有一个数组，其元素不能直接访问。尝试

<h5 class="padding-left">FORNECEDOR</h5>
<ion-item class="item item-text-wrap">
    <p> {{ order.Identifier }}
        <br>{{ order.Name }}
        <br> {{ order.Street }} - {{ order.City }}
        <br> {{ order.PostalCode }}
    </p>
    <p ng-repeat="item in order.OrderLine">
        LineNumber: {{item.LineNumber}}
        StandardProductCode: {{item.StandardProductCode}}
    </p>
</ion-item>

现在这个item是order.OrderLine数组中的嵌套项。

希望这有帮助。
