您好我正在使用AngularJS更新多个实体（您会称之为页面）。这些实体具有我希望用户通过选择下拉列表选择的标签。当我获取实体集合的数据时，我获取已经选择的标记并将其存储在该元素的数组中。
我有一个演示，我已经用所有选项的列表填充了选择，并且我在ng-repeat中输出实体数据，但是我无法传入已经选择的选项。
我的代码如下;

如您所见，我正在尝试访问select中ng-model中的entity.data.selected_tags.effort。 entity.data.selected_tags.effort对应下面我的角度控制器中$ scope.tasks中存在的数据。
<div ng-app="app">
<div ng-controller="Controller">
<div ng-repeat="entity in tasks.entities">
<input class="form-control" type="text" name="entity['{{entity.data.UID}}']" ng-model="entity.data.name" />
<select ng-model="entity.data.selected_tags.effort" ng-options="effort as effort.value group by effort.category for effort in effortTags"></select>
</div>
</div>
</div>
我有什么想法可以在这个重复中获得所选的选项吗？
答案 0 :(得分：-1)
您可以使用“ng-repeater”在选择内重复您的选项：
https://jsfiddle.net/s9fLw40v/6/
类似的东西：
<select ng-model="entity.data.selected_tags.effort">
<option ng-repeat="effort in effortTags" value="{{effort.value}}">{{effort.value}}</option>
</select>
