我向AngularJS Guru提出了一个问题。是否可以从下一个列表中删除空白值，其中 klassList 是一些对象列表。我需要完全 ng 重复而不是ng 选项[{"id":1,"klassName":"11A","pupils":null},{"id":2,"klassName":"12B","pupils":null}]：
<input type="text" class="form-control" ng-model="klassName1"/>
<select class="form-control" ng-model="selectedItem" >
<option ng-repeat="klass in klassList | filter : {klassName : klassName1}">{{klass.klassName}}</option>
</select>
我的目标是获取可以过滤值的下拉列表。
使用ng-options
ng-options="givendata as givendata .klassName for givendata in klassList"
angular.module('app', []).controller('SelectorCtrl', function($scope) {
$scope.klassList = [{"id":1,"klassName":"11A","pupils":null},{"id":2,"klassName":"12B","pupils":null}];
