我正在创建一个带有 ng-options 的选择，它循环遍历链接到 ng-init 的对象数组。然而，问题是，它还必须通过 ng-change 传递正确的变量。
现在下面的代码将使 ng-init 工作并在加载时选择正确的选项。 However, when the options are selected it doesn't pass the id to the ng-change
<select name="baddress" ng-init="autoship.baddress_id = address.id || addresses[0]"
ng-model="autoship.baddress_id"
ng-change="setter('baddress', autoship, address.id)"
ng-options="address as address.address + ' ' + address.address2 + ' ' + address.city + ', ' + address.state + ' ' + address.zipcode for address in addresses" ></select>
通过在 ng-options 开头的 address 中添加 .id，ng-change工作完美，但它在加载时将选择下拉列表留空。
<select name="baddress"
ng-init="autoship.baddress_id = address.id || addresses[0]"
ng-model="autoship.baddress_id"
ng-change="setter('baddress', autoship, address.id)"
ng-options="address.id as address.address + ' ' + address.address2 + ' ' + address.city + ', ' + address.state + ' ' + address.zipcode for address in addresses" ></select>
最佳答案
adresses[0] 将是这一行中的整个地址对象:
ng-init="autoship.baddress_id = address.id || addresses[0]"
为了只保留id，我觉得你应该改成:
ng-init="autoship.baddress_id = address.id || addresses[0].id"
