//controller
app.controller('myCtrl',function($scope){
$scope.quiz = {one:"", two:""};
$scope.show = function(){
alert("Done");
}
$scope.reset = function(){
angular.forEach($scope.quiz,function(val, key){
val = "";
val.checked = false;
});
}
});
</script>

请像这样更改重置功能。这会起作用的。
$scope.reset = function () {
angular.forEach($scope.quiz, function (val, key) {
$scope.quiz[key] = "";
});
}
