AngularJS 获取变量中选定下拉选项的值

Question

我有下拉选择菜单，想在 api 的请求参数中发送下拉选择的值。我的代码是...

<select class="form-control" id = "SelectionInput_reason">
   <option name="careerType" value="type_1">Career</option>
   <option name="examType" value="type_2">Exams</option>
</select>

getValue = function() {
    var selectedValue = this.value;
    var selectedText = this.options[this.selectedIndex].getAttribute('name');
    alert(selectedValue); 
    alert(selectedText); 
} 
document.getElementById('SelectionInput_reason').addEventListener('change', getValue );

如果可能请在angularJS中给出答案...

还有我如何在变量中获取 tinymceeditor 的文本输入？

$scope.tinymceModel = 'Initial content';
        $scope.getContent = function() {
          console.log('Editor content:', $scope.tinymceModel);
        };
        $scope.setContent = function() {
          $scope.tinymceModel = 'Time: ' + (new Date());
        };
        $scope.tinymceOptions = {
          selector: 'textarea',
          //plugins: 'link image code',
          toolbar: ' bold italic | undo redo | alignleft aligncenter alignright | code'
        };

HTML 是..

<div class="form-group">
     <textarea ui-tinymce="tinymceOptions" id="jander" ng-model="tinymceModel" placeholder="Ask your question" class="form-control"></textarea>
 </div>

Answer 1

在 select 下拉列表中绑定 model。喜欢下面

<select class="form-control" id = "SelectionInput_reason" data-ng-model="inputReason">

在您的控制器中，您将获得 selected 选项

console.log($scope.inputReason)

Answer 2

这是附有 fiddle 的示例代码

var myApp = angular.module('myApp', []);

myApp.controller('MyCtrl', function($scope) {

  $scope.shelf = [{
    'name': 'Banana',
    'value': ''
  }, {
    'name': 'Apple',
    'value': ''
  }, {
    'name': 'Pineapple',
    'value': ''
  }, {
    'name': 'Blueberry',
    'value': ''
  }];

  $scope.cart = {
     'fruit': $scope.shelf[0]
  };
});

<div ng-controller="MyCtrl">
  <div>
    Fruit List:
    <select ng-model="cart.fruit" ng-options="state as state.name for state in shelf"></select>
    <br/>
    <tt>Cost & Fruit selected: {{cart.fruit}}</tt>
  </div>

</div>

在这种情况下，我的建议是尝试将所有输入选项保留为 Js 对象（如此代码中的 $scope.shelf），因为这就是 Angular 为严格和稳健地处理数据，最终你可以只从服务器或 json 文件加载这些选项，而根本不必触摸你的 HTML！

希望对您有所帮助！
