HTML：

 <select id ="red" style="width:90%;" class="form-control state state1" name="state_list" ng-change="getstate(0)" ng-model="usercountry[0]">
    <option value="">--Country--</option>
    <option ng-repeat="country in countryies" ng-selected="country.id==selectedCountryvalue[0]" value="{{country.id}}">{{country.country}}</option>

Answer 1

ng-options可帮助您将对象绑定到选择值。

尝试这样的事情：

HTML

{{usercountry}}
<select ng-options="country as country.country for country in countries" ng-model="usercountry"></select>

angularJS

$scope.countries = [
    {id: 0, country: "Italy"}, {id: 1, country: "Greece"}
];

$scope.usercountry = $scope.countries[0];
