依据『巧用过渡』的设计原则，Ant Design 提供了一些预设的组件动画和缓动函数。

示例延长了动画时长以便展示。

const cssAnimation = require('css-animation');
const Select = antd.Select;
const Option = Select.Option;
const OptGroup = Select.OptGroup;

let motions = [];
motions = motions.concat([[{
  name: '淡入',
  value: 'fade',

  type: '渐隐'
}, {
  name: '淡出',
  value: 'fade',
  direction: 'leave',
  type: '渐隐'
}]]);
motions = motions.concat([[{
  name: '中心放大',
  value: 'zoom',
  direction: 'enter',
  type: '缩放'

var leave = '-leave';

ReactDOM.render(<Test key="motion" />, mountNode);

组件动画

在 React 的前端实现中，可以使用 rc-animate 的 transitionName 属性来给任意元素指定动画。

缓动函数

move@enter 表示 移动@进入。
