Question

我有一个问题是为角度中的ui-select2预选一组变量。

我的控制器：

$scope.roles= [{"_id":"545e8f2f64f29dc1540f5a88","__v":0,"created":"2014-11-08T21:46:23.553Z","comments":"Administrator Rolle","name":"admin"}];

$scope.userdata.roles = [{"_id":"545e8f2f64f29dc1540f5a88","__v":0,"created":"2014-11-08T21:46:23.553Z","comments":"Administrator Rolle","name":"admin"}];

我的观点：

<ui-select multiple ng-model="userdata.roles" theme="select2" ng-disabled="disabled" class="input-medium" style="width:100% !important;">
    <ui-select-match placeholder="Wählen Sie ein oder mehrere Rollen...">{{$item.name}}</ui-select-match>
    <ui-select-choices repeat="role in roles | filter:$select.search">
        {{role.name}} ({{role.comments}})
    </ui-select-choices>
</ui-select>

ng-model不要预先选择值

当我分配$scope.userdata.roles = $scope.roles它将起作用。

如果可能，我想使用这个数组，但我无法用这个代码编写：

$scope.roles= [{"_id":"545e8f2f64f29dc1540f5a88","__v":0,"created":"2014-11-08T21:46:23.553Z","comments":"Administrator Rolle","name":"admin"}];

$scope.userdata.roles = ["admin"];

编辑：当我使用它作为我的观点时：

<ui-select multiple ng-model="userdata.roles" theme="select2" ng-disabled="disabled" style="width:100% !important;">
    <ui-select-match placeholder="Bitte wählen Sie eine oder mehrere Rollen...">{{$item.name}} &lt;{{$item.comments}}&gt;</ui-select-match>
    <ui-select-choices repeat="role.name as role in roles">
        <div ng-bind-html="role.name | highlight: $select.search"></div>
        <small>
            {{role.comments}}
        </small>
    </ui-select-choices>
</ui-select>

这是我的控制器：

$scope.roles            = [ 
        {
            "_id" : "545e8f2f64f29dc1540f5a88",
            "__v" : 0,
            "created" : "2014-11-08T21:46:23.553Z",
            "comments" : "Administrator Rolle",
            "name" : "admin"
        }
    ];
$scope.userdata.roles = ["admin"];

它也行不通。时机有问题吗？

Answer 1

您需要从数组中选择要设置为默认值的整个对象，如

$scope.roles= [{"_id":"545e8f2f64f29dc1540f5a88","__v":0,"created":"2014-11-08T21:46:23.553Z","comments":"Administrator Rolle","name":"admin"}];

$scope.userdata.roles = $scope.roles[0] //set first record as default;

Answer 2

关键是将$ parent添加到我的ngmodel var。

ui-select2多个init值
