Question

我有这些单选按钮，但我无法从提交中获得价值。我试过这个：http://plnkr.co/edit/4lvJclZuh0lryF1nhmdt?p=preview

HTML：

        <body ng-controller="ExamCtrl">
           <form name="myForm" ng-submit="submitForm()">
             <label><input type="radio" name="test" ng-model="radioValue" value="1"/> One</label>
             <label><input type="radio" name="test" ng-model="radioValue" value="2"/> Two</label>
             <label><input type="radio" name="test" ng-model="radioValue" value="3"/> Three</label>
             <div>currently selected: {{radioValue}}</div>
             <button type="submit">Submit</button>
           </form>
        </body>

JS：

   $scope.submitForm = function () {
       console.log('Submitting');
       console.log($scope.radioValue);
   };

记录“正在提交”，然后记录undefined。

当我使用点'时，它有效。'符号。不知道为什么。

HTML

<body ng-controller="ExamCtrl">
   <form name="myForm">
     <label><input type="radio" name="test" ng-model="radio.value" value="1"/> One</label>
     <label><input type="radio" name="test" ng-model="radio.value" value="2"/> Two</label>
     <label><input type="radio" name="test" ng-model="radio.alue" value="3"/> Three</label>
     <div>currently selected: {{radioValue}}</div>
     <button ng-click="submitAnswer(radio.value)">Submit</button>
   </form>
</body>

JS

$scope.submitAnswer = function (selected) {
  // $scope.answer = 'A';
  console.log('submitting');        
  console.log(selected);
};

var myApp = angular.module('myApp',[]);

myApp.controller('MyCtrl',function($scope) {
   $scope.submitForm = function () {
       console.log('Submitting');
       console.log($scope.radioValue);
