formetfromsont écrits de manière si confusePourquoi ne pas utiliser la radio
Si vous voulez vraiment faire ça, vous pouvez
$scope.check=function(){
var vérifié=[];
si(!$scope.formData.favoriteColors){
retourner faux ;
>
si($scope.formData.favoriteColors.red)
checké.push('red');
si($scope.formData.favoriteColors.blue)
checké.push('bleu');
si($scope.formData.favoriteColors.green)
checké.push('vert');
}`
