Ionic/Angular 在列表中检索选定的电台

Question

我正在使用 Ionic，但我很难检索选定的单选按钮。

以下是我的HTML

<div class="list">
  <label class="item item-radio">
    <input type="radio" name="group" ng-model="answer">
      <div class="item-content">
        Canada
      </div>
    <i class="radio-icon ion-checkmark"></i>
  </label>
  <label class="item item-radio">
    <input type="radio" name="group" ng-model="answer">
      <div class="item-content">
        Africa
      </div>
    <i class="radio-icon ion-checkmark"></i>
  </label>
  <label class="item item-radio">
    <input type="radio" name="group" ng-model="answer">
      <div class="item-content">
        North America
      </div>
    <i class="radio-icon ion-checkmark"></i>
  </label>
</div>

关于如何解决这个问题有什么建议吗？有没有办法在选择答案后从 $scope 访问模型对象？

Answer 1

您的单选按钮没有任何值属性。为单选按钮设置一个值，您可以使用 $scope.answer 访问该值

<!DOCTYPE html>
<html ng-app>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <link href="https://code.ionicframework.com/1.0.0/css/ionic.min.css" rel="stylesheet">
    <script src="https://code.ionicframework.com/1.0.0/js/ionic.bundle.js"></script>
  </head>
  <body ng-app="app">
    <ion-pane>
      <ion-header-bar class="bar-stable">
        <h1 class="title">Awesome App</h1>
      </ion-header-bar>
      <ion-content class="padding">
      Selected Answer {{answer}}
        <div class="list">
  <label class="item item-radio">
    <input type="radio" name="group" ng-model="answer" value="Canada">
      <div class="item-content">
        Canada
      </div>
    <i class="radio-icon ion-checkmark"></i>
  </label>
  <label class="item item-radio">
    <input type="radio" name="group" ng-model="answer" value="Africa">
      <div class="item-content">
        Africa
      </div>
    <i class="radio-icon ion-checkmark"></i>
  </label>
  <label class="item item-radio">
    <input type="radio" name="group" ng-model="answer"  value="North America">
      <div class="item-content">
        North America
      </div>
    <i class="radio-icon ion-checkmark"></i>
  </label>
</div>
      </ion-content>
    </ion-pane>
  </body>
</html>
