javascript - ngAnimate CSS 动画不适用于 ng-show 和 ng-hide

Question

演示: http://plnkr.co/edit/cPDUWO?p=preview

我在页面上显示了 2 个选中的复选框和 2 个小部件。单击复选框将使用 ng-show 和 ng-hide 来隐藏和显示相应的小部件。现在我也想有一个基本的 fadeIn 和 fadeOut，但是到目前为止运气不好 :( 显示/隐藏的小部件没有任何淡入淡出动画。你能看到我在哪里吗？我出错了吗？

Controller

animateApp.controller('mainController', function($scope) {
    $scope.pageClass = 'page-home';
    $scope.widget_manage_quotes = true;
    $scope.widget_manage_customer = true;
});

CSS

.reveal-animation.ng-enter {
    -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */
    animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */
}

.reveal-animation.ng-leave {
    -webkit-animation: leave_sequence 1s linear; /* Safari/Chrome */
    animation: leave_sequence 1s linear; /* IE10+ and Future Browsers */
}

@-webkit-keyframes enter_sequence {
    0% { opacity:0; }
    100% { opacity:1; }
}

@keyframes enter_sequence {
    0% { opacity:0; }
    100% { opacity:1; }
}

@-webkit-keyframes leave_sequence {
    0% { opacity:1; }
    100% { opacity:0; }
}

@keyframes leave_sequence {
    0% { opacity:1; }
    100% { opacity:0; }
}

HTML

<ul>
    <li>
        <input
            ng-click="widget_manage_quotes = !widget_manage_quotes"
            type="checkbox" 
            name="w_manage_quotes"
            id="w_manage_quotes" 
            class="css-checkbox"
            checked />

        <label for="w_manage_quotes" class="css-label radGroupWidgetOptions">Toggle Widget 1</label>
    </li>
    <li>
        <input
            ng-click="widget_manage_customer = !widget_manage_customer"
            type="checkbox" 
            name="w_manage_customers"
            id="w_manage_customers" 
            class="css-checkbox"
            checked />

        <label for="w_manage_customers" class="css-label radGroupWidgetOptions">Toggle Widget 2</label>
    </li>
  </ul>

  <div ng-show="widget_manage_quotes" class="manage_content dash_widget reveal-anim   ation">
    <div class="widget_box box1">
      <h1>Widget 1!</h1>
    </div>
  </div>

  <div ng-show="widget_manage_customer" class="manage_content dash_widget reveal-animation">
    <div class="widget_box box2">
      <h1>Widget 2!</h1>
    </div>
  </div>

Answer 1

看起来正确的样式应该包括 .ng-hide-add 和 .ng-hide-remove:

.reveal-animation.ng-hide.ng-hide-add-active {
    display: block !important;
}
.reveal-animation.ng-hide-remove {
    -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */
    animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */
}
.reveal-animation.ng-hide-add {
    -webkit-animation: leave_sequence 1s linear; /* Safari/Chrome */
    animation: leave_sequence 1s linear; /* IE10+ and Future Browsers */
}

我还必须为 .ng-hide.ng-hide-add-active 添加样式，以防止 ng-hide 在动画期间立即隐藏元素。
