Ionic AngularJS Radio Group ng-model issue using ion-radio

I'm unable to retrieve the value of the Radio Group using AngularJS 1.4.7 with Ionic 1.1.1;

Any ideas would be great, thanks.

            <form class="list" ng-submit="Pass(test)">
                <p>Selected Sample: {{test.val}}</p>
                <ion-radio ng-model="test.val" ng-value="s1">Sample 1</ion-radio>
                <ion-radio ng-model="test.val" ng-value="s2">Sample 2</ion-radio>
                <button class="button button-energized button-large icon-right button-full">Test</button>
            </form>

        </ion-content>      
    </body>
</html>

Javascript

angular.module('app', ['ionic'])
.controller('myCtrl', function($scope) {
  $scope.Pass = function($test) {
    alert("Test: "+$test.val);
  }  
});
Solution

  • Try the following: 

    angular.module('app', ['ionic'])
.controller('myCtrl', function($scope) {
 $scope.test = {};
 $scope.Pass = function($test) {
   alert("Test: "+ $scole.test.val);
 }  
});

    Explanation:

    1. $test is not defined in your $scope.
    2. variables starting with $ have a special meaning in angular, so you shouldn't use them as regular variable names

    Update: It's also important to singelquote a string value within the double quoted ng-value

    <ion-radio ng-model="test.val" ng-value="'s1'">Sample 1</ion-radio>
