Javascript 在本例中，如何从js更改选择选项

如何从javascript/Angularjs后端选择标记选项

提示：我实际上是从API服务中获取数据，然后填写一个表单以供编辑。假设性别是男性，我怎样才能使tage变成数据库中的男性呢。例如，用户可以将其更新为女性

这是我的密码：

$scope.Gender = [
{ GenderID: "Mmale", name: "Mmale" },
{ GenderID: "Female", name: "Female" }
];

HTML

这里是一个示例，您只需为

ng model

提供要选择的

GenderID

：

HTML:

<select class="form-control" name="Gender" ng-model="GenderID" ng-options="g.GenderID as g.name for g in Gender" required style="width:98px; color:gray">
                    <option value="" style="" >Gender?</option>
                </select>

$scope.Gender.name = $scope.users[id].Gender;
$scope.Gender.GenderID = $scope.users[id].Gender;

<div ng-app ng-controller="MyCtrl">
    <select class="form-control" name="Gender" ng-model="GenderID" ng-options="g.GenderID as g.name for g in Gender" required style="width:98px; color:gray">
        <option value="" style="" >Gender?</option>
    </select>
</div>

function MyCtrl($scope, $filter) {
    $scope.Gender = [
        { GenderID: "Mmale", name: "Mmale" },
        { GenderID: "Female", name: "Female" }
    ];

    $scope.GenderID = "Mmale";
}
