我想像时钟类型的动画一样创建它.. 在此当用户单击 NO -> 箭头将关闭动画 然后当用户点击 May Be... 它会从 No 开始到 May be .. 但是现在..它从第一帧开始..可能是一样的..

Answer 1

只需使用css-transition 而不是css-animation

1. 用于.dial 元素集transition:all 1s ease;（或根据需要自定义）。
2. 对于.rotate90、.rotate180 和.rotate270，而不是动画将其替换为transform: rotateZ(your_deg);

像这样：

var app = angular.module('dialApp', ['ngAnimate']);

angular.module('dialApp').controller('MainController',['$scope', function ($scope) {
  $scope.test = 'Test';

  $scope.left = false;
  $scope.right = false;
  $scope.bottom = false;
  $scope.leftRotate = function () {
    $scope.left = true;
    $scope.right = false;
    $scope.bottom = false;
  }

  $scope.rightRotate = function () {
    $scope.left = false;
    $scope.right = true;
    $scope.bottom = false;
  }

  $scope.bottomRotate = function () {
    $scope.left = false;
    $scope.right = false;
    $scope.bottom = true;
  }

}]);
