Answer 1

刪除插值括號{{}}：

<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>

根據你的數據我編輯了我的答案：

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 }] 
 
}
