ng-options，包含鏈接到ng-init的對象數組

Question

我正在使用ng-options創建一個select，它遍歷鏈接到ng-init的對象數組。 但問題是，它必須通過ng-change傳遞正確的變量。

現在，下面的代碼將使ng-init工作並在加載時選擇正確的選項。 但是，選擇選項時，它不會將id傳遞給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>

通過添加.id以address中的開頭ng-options中， ng-change完美的作品，但它留下的選擇下拉空負載。

<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>

Answer 1

adresses [0]將是此行中的整個地址對象：

ng-init="autoship.baddress_id = address.id || addresses[0]" 

為了只保留id，我認為你應該把它改為：

ng-init="autoship.baddress_id = address.id || addresses[0].id"
