如何在AngularJS中获取onchange后的选项文本值

<select ng-model="selectedOption" ng-change="onChange()">
  <option value="option1">Option 1</option>
  <option value="option2">Option 2</option>
  <option value="option3">Option 3</option>
</select>

$scope.onChange = function() {
  var selectedText = $scope.selectedOption;
  var options = $scope.options;
  for (var i = 0; i < options.length; i++) {
    if (options[i].value === selectedText) {
      var selectedOptionText = options[i].text;
      console.log(selectedOptionText);
      break;
    }
  }
};

$scope.options = [
  { value: 'option1', text: 'Option 1' },
  { value: 'option2', text: 'Option 2' },
  { value: 'option3', text: 'Option 3' }
];
