# 卡片加载中

- order: 3

可以直接把内容内嵌到 `Spin` 中，将现有容器变为加载状态。

import { Spin, Switch, Alert } from 'antd';

const Card = React.createClass({

      type="info" />;
    return <div>
      <Spin spining={this.state.loading}>{container}</Spin>
      切换加载状态：<Switch checked={this.state.loading} onChange={this.toggle} />
    </div>;
  }
