在SELECT中不起作用ng-options

Question

I am trying to populate States in Select with ng-options . As i am new to angular, result doesn't come as expected.

Controller

$scope.statesList = function () {
        StatesList.query(function (states) {
            $scope.states = states;            
        });
    };

Html

<td data-ng-init="statesList()">
    <select ng-model="practiceAdd.state" name="state{{$index+1}}" ng-class="{'has-error': editForm.{{$index+1}}.$invalid}" 
        ng-options="state in states" required>
    </select>                                                                
</td>

Array

$$hashKey: "05S"
_id: "53107e099d985dc404000015"
city: "mumbai"
country: "india"
state: "AR"
street: "1"
zipcode: 42101

Try like This..

In HTML

<select name="countries" id="countries" ng-model="countryCode" ng-options="country.code as country.name for country in countries"></select>

In angular JS Code

  $scope.countries = [
    {
      name: 'Poland',
      code: 'PL'
    },
    {
      name: 'United Kingdom',
      code: 'UK'
    },
    {
      name: 'United States of America',
      code: 'USA'
    }
  ];
  $scope.countryCode = 'UK';

Working Exaple

In your Example ;

<td>
    <select ng-model="state.Id" name="state{{$index+1}}" ng-options="state.Id as state.name for state in states" required>
    </select>                                                                
</td>

State id and state name should be defined by you.
