    $scope.Parents = data.data;
});

<select class="form-control" ng-model="modelparent">
                                <option value="{{parent.ParentID}}" ng-selected="{{parent.ParentID==2}}" ng-repeat="parent in Parents">{{parent.DocumentNo}} -  {{parent.FullName}}</option>
                            </select>

Answer 1

从ng-selected中删除插值大括号{{}}并尝试：

<select class="form-control" ng-model="modelparent">
                            <option value="{{parent.ParentID}}" ng-repeat="parent in Parents"  ng-selected="parent.ParentID==2">{{parent.DocumentNo}} -  {{parent.FullName}}</option>
                        </select>

根据您的数据，我编辑了我的答案：

var app=angular.module("app",[]); app.controller('Ctrl',['$scope',Ctrl]); function Ctrl($scope){ $scope.modelparent = "1"; $scope.Parents = [{ "ParentID": 1, "FullName": "Jack", "BirthDate": "/Date(631137600000)/", "BirthPalace": 1, "DocumentType": 1, "DocumentNo": "P544123", "AddDate": "/Date(1483300800000)/", "UpdateDate": null, "LastLoginDate": null }, { "ParentID": 2, "FullName": "Ammanda", "BirthDate": "/Date(631137600000)/", "BirthPalace": 1, "DocumentType": 1, "DocumentNo": "P5441234", "AddDate": "/Date(1483300800000)/", "UpdateDate": null, "LastLoginDate": null }] }

AngularJS ng-options设置默认选择值
