[SOLVED] angularjs ng-repeat radio buttons

angularjs ng-repeat radio buttons

This code makes 2 sets of 3 radio buttons. One set of individual radio buttons and one set of radio buttons constructed with an ng-repeat. Both sets of radio buttons can be selected with the buttons A-C or they can be clicked on themselves.

However: when you have clicked on the ng-repeat radio buttons, they are no longer selected with the buttons A-C. Why?

angular.module('radioExample', [])
  .controller('ExampleController', ['$scope', function($scope) {
    $scope.color = {
      name: 'blue'
    };
    $scope.radiomodel = 'blue';
    $scope.radiovalues = ['red', 'green', 'blue'];

    $scope.clickA = function() {
      $scope.color.name = 'red';
      $scope.radiomodel = 'red';
    }

    $scope.clickB = function() {
      $scope.color.name = 'green';
      $scope.radiomodel = 'green';
    }

    $scope.clickC = function() {
      $scope.color.name = 'blue';
      $scope.radiomodel = 'blue';
    }

    $scope.radioclick = function(index) {
      $scope.clickvalue = index;
    }

    $scope.radiochange = function(index) {
      $scope.changevalue = index;
    }

  }]);

Solution

The problem is that you use wrong ng-model inside ng-repeat. I changed

ng-model="radiomodel"

into

ng-model="color.name"

Here is the working example: https://jsfiddle.net/avgustin/x5q8kfdv/
