# 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。

````jsx
import { Spin, Switch } from 'antd';

const Card = React.createClass({
  getInitialState() {
    return {
      loading: false
    };
  },
  toggle(value) {
    this.setState({
      loading: value
    });
  },
  render() {
    const card = <div className="card-example" />;
    return <div>
      {this.state.loading ? <Spin>{card}</Spin> : card}
      切换加载状态：<Switch checked={this.state.loading} onChange={this.toggle} />
    </div>;
  }
});

ReactDOM.render(<Card />, document.getElementById('components-spin-demo-nested'));
````

````css
.card-example {
  border-radius: 4px;
  padding: 24px;
  height: 100px;
  border: 1px solid #e9e9e9;
