Javascript AngularJS如何从ng选项中选择值

我在选择ng选项中插入值，我想在特定月份的下拉列表中选择。 这是返回所有12个月的arrray，所以如何从下拉列表中仅获取所选月份

脚本：

$scope.Month = ['Jan', 'Feb', 'March', 'April', 'May', 'June', 'July', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
 $scope.selectmonth = $scope.Month;

 $scope.SaveReport = function () {

    PrintReportRepository.save(
            {
             SelectMonth: $scope.selectmonth,
             },

html

 <select class="form-control" ng-model="selectmonth" ng-options ="months as months for months in Month">{{months}}</select>

{{months}

要设置所选的第一项，请使用

$scope.selectmonth=$scope.Month[0]

，通过设置

$scope.selectmonth=$scope.Month

U将整个阵列设置为一个模型使用此代码：请参阅

控制器：

$scope.Month = ['Jan', 'Feb', 'March', 'April', 'May', 'June', 'July', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
 $scope.SaveReport = function () {
    console.log('SelectMonth', $scope.selectmonth);
 }

html:

<select class="form-control" ng-model="selectmonth" ng-options ="months as months for months in Month" ng-change="SaveReport()"></select>
