 <select data-ng-model="userInf.role" class="span12" required>
    <option value="" selected="selected" disabled="disabled">Choose one</option>
    <option data-ng-repeat="role in roles" value="{{ role.text }}">{{ role.text }}</option>
</select>

有角度的

userService.getUser($scope.userInf,
        function( data ) // success
        {

        $scope.userInf = {
                username: data.userName,
                firstname: data.firstName,
                middlename: data.middleName,
                lastname: data.lastName,
                title: data.title,
                organization: data.organization,
                role: data.authorization.role,
                dateOfBirth:data.dateOfBirth,
                save: 'update'              
            };
        },

其他文件即将到来，但选择值未到来

在检查元素中我可以看到

<select data-ng-model="userInf.role" class="span12 ng-pristine ng-valid ng-valid-required" required="">
        <option value="? string:Analyst ?"></option>
        <option value="" selected="selected" disabled="disabled">Choose one</option>
        <!-- ngRepeat: role in roles --><option data-ng-repeat="role in roles" value="Analyst" class="ng-scope ng-binding">Analyst</option>
        <option data-ng-repeat="role in roles" value="Admin" class="ng-scope ng-binding">Admin</option>
        </select>

我知道 Angular 有为此目的的 ng-init 指令。你为什么不试试 ng-options 指令？您可以将 ng-init 指令与 ng-options 一起使用，并且 ng-options 比 ng-repeat 更灵活一些。

<select ng-model="userInf.role" ng-options="role for role in roles" ng-init="userInf.role = '' " class="span12 ng-pristine ng-valid ng-valid-required" required="">
    <option value="" disabled="disabled">Choose one</option>
</select>

ng-init 会将您的 ng-model（下面定义的选项的值）设置为您想要的任何值，在这种情况下，将您的 ng-model 设置为 '' 这是您的第一个选项的值。ng-options 将使用数组中的值为您填充其余选项。您可能需要一些设置才能在选项中显示正确的名称和值。看这里https://docs.angularjs.org/api/ng/directive/select

是的，我会这样做：


var app = angular.module('app', [])
app.controller('exampleCtrl', function ($scope) {
  $scope.options = ["a", "b", "c"]
  $scope.selected = $scope.options[1]

})


<select ng-options="o for o in options" ng-model="selected"></select>

加载时将选择选项“b”
