我可以将对象数组传递给 filterBy 吗？

Question

我的ember版本是1.13，请问下面这行代码是否适用于我上面的ember应用版本？

console.log(this.get('arrayOfObjects').filterBy('zoneName', ['zoneNameOne', 'zoneNameTwo'])); ?

selectedZoneOrCityName的样本数据为

selectedZoneOrCityName = ['zoneNameOne', 'zoneNameTwo'],

我想像这样使用它

if (selectedZoneOrCityName) {
  return this.get('arrayOfObjects').filterBy('zoneName', selectedZoneOrCityName).mapBy('cityName');
} else {
  console.log('reads nothing');
  return [];
}

您可以像下面的代码片段一样使用简单的 filter。

var arrayOfObjects = [
  {
    id: 1,
    name: 'one',
    zoneName: 'zoneNameOne'
  },
  {
    id: 2,
    name: 'two',
    zoneName: 'one zoneName'
  },
  {
    id: 3,
    name: 'three',
    zoneName: 'zoneNameOne'
  },
  {
    id: 4,
    name: 'four',
    zoneName: 'zoneNameTwo'
  }
];

var selectedZoneOrCityName = ['zoneNameOne', 'zoneNameTwo'];
 arrayOfObjects = arrayOfObjects.filter((item) => {
   return selectedZoneOrCityName.includes(item.zoneName);
 });
 
 console.log('final filtered array : ', arrayOfObjects);

如果您使用 filterBy，那么您必须 chain 对每个数组值进行过滤。

Can I pass an array of object to filterBy?
