AngularJS如何在下拉菜单上获取多个值更改值

<select ng-model="selectedValues" multiple>
  <option value="value1">Value 1</option>
  <option value="value2">Value 2</option>
  <option value="value3">Value 3</option>
</select>

app.controller('myController', function($scope) {
  $scope.selectedValues = []; // 初始化一个空数组

  $scope.updateValues = function() {
    console.log($scope.selectedValues); // 打印所选值
  };
});

<select ng-model="selectedValues" ng-change="updateValues()" multiple>
  <option value="value1">Value 1</option>
  <option value="value2">Value 2</option>
  <option value="value3">Value 3</option>
</select>
