Using the Ionic framework, I'm trying to create a group of three buttons that act as radio buttons:
If I click on Breakfast, I would like Lunch and Dinner to return to their normal (white) state, and Breakfast to turn Blue.
With my current code, I can't get this functionality to work, although I can get the buttons to switch color, slightly randomly (perhaps I just don't understand the ng-class
directive).
Here is my HTML code:
<div class="bar bar-subheader">
<div class="button-bar">
<a class="button" ng-class="{'button-positive' : !isActiveB, 'none': isActiveB}" ng-click="active('breakfast')">Breakfast</a>
<a class="button" ng-class="{'button-positive' : !isActiveL, 'none': isActiveL}" ng-click="active('lunch')">Lunch</a>
<a class="button" ng-class="{'button-positive' : !isActiveD, 'none': isActiveD}" ng-click="active('dinner')">Dinner</a>
</div>
</div>
My JS:
$scope.active = function(meal) {
switch (meal) {
case 'breakfast':
$scope.$broadcast('slideBox.setSlide', 0);
$scope.isActiveB = $scope.isActiveB;
$scope.isActiveL = !$scope.isActiveL;
$scope.isActiveD = !$scope.isActiveD;
break;
case 'lunch':
$scope.$broadcast('slideBox.setSlide', 1);
$scope.isActiveB = !$scope.isActiveB;
$scope.isActiveL = $scope.isActiveL;
$scope.isActiveD = !$scope.isActiveD;
break;
case 'dinner':
$scope.$broadcast('slideBox.setSlide', 2);
$scope.isActiveB = !$scope.isActiveB;
$scope.isActiveL = !$scope.isActiveL;
$scope.isActiveD = $scope.isActiveD;
break;
}
};
I can put the code in JSFidle if you require more information and a working solution.
Thanks for your help.
NOTE: I would like to maintain my active()
function, and use the ng-class
directive if possible, as I have a lot of other code dependent on this function.
Maybe this simplified example will help you a little:
<div class="button-bar">
<a class="button" ng-class="{'button-positive': isActive('breakfast')}" ng-click="setActive('breakfast')">Breakfast</a>
<a class="button" ng-class="{'button-positive': isActive('lunch')}" ng-click="setActive('lunch')">Lunch</a>
<a class="button" ng-class="{'button-positive': isActive('dinner')}" ng-click="setActive('dinner')">Dinner</a>
</div>
Controller:
$scope.active = 'breakfast';
$scope.setActive = function(type) {
$scope.active = type;
};
$scope.isActive = function(type) {
return type === $scope.active;
};
Here is a more flexible solution for future Googlers.
Working plunker: http://plnkr.co/edit/U2Hvx4?p=preview
.directive('barSelect',function($parse){
return {
restrict: 'A',
require: 'ngModel',
scope: {
model: '=ngModel',
value: '=barSelect'
},
link: function(scope, element, attrs, ngModelCtrl){
element.addClass('button');
element.on('click', function(e){
scope.$apply(function(){
ngModelCtrl.$setViewValue(scope.value);
});
});
scope.$watch('model', function(newVal){
element.removeClass('active');
if (newVal === scope.value){
element.addClass('active');
}
});
}
};
});
And a usage example:
<div class="button-bar">
<a bar-select="button.value"
ng-repeat="button in clientSideList"
ng-model="data.clientSide"
>{{button.text}}</a>
</div>
