从列表中访问属性

Question

我想以选择标签中的选项的形式访问项目中的时间段。

角js模块和列表

     var dynamicApp = angular.module('dynamicApp', []);  
       dynamicApp.controller('maincontroller', function($scope) {
    $scope.invoice = {
    items: [{
         loyality: [{name:'points'},{name:'credits'}],
         value:1,
    period: [{name:'activity1'},{name:'activity2'}]
        }]
  };
      $scope.removeItem = function(index) {
    $scope.list.splice(index, 1);
   }    

    });

选择标记的html代码

 <td><select ng-model=" pts"  ng-options="lists.items.period for lists in   invoice.items  " ></select></td>

Answer 1

以下是HTML代码：

<select ng-model="pts" ng-options="item as item.name for item in invoice.items[0].period track by $index" ></select>

还有一个有用的例子：
