Skeleton骨架屏

在需要等待加载内容的位置提供一个占位图形组合。

何时使用#

  • 网络较慢,需要长时间等待加载处理的情况下。

  • 图文信息内容较多的列表/卡片中。

  • 只在第一次加载数据的时候使用。

  • 可以被 Spin 完全代替,但是在可用的场景下可以比 Spin 提供更好的视觉效果和用户体验。

代码演示

最简单的占位效果。

import { Skeleton } from 'infrad';
import React from 'react';

const App: React.FC = () => <Skeleton />;

export default App;

更复杂的组合。

expand codeexpand code
import { Skeleton } from 'infrad';
import React from 'react';

const App: React.FC = () => <Skeleton avatar paragraph={{ rows: 4 }} />;

export default App;

显示动画效果。

import { Skeleton } from 'infrad';
import React from 'react';

const App: React.FC = () => <Skeleton active />;
