angularjs ng-repeat radio buttons
Question
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 AC 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 AC. 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; } }]);

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/
