# Steps 组件名

## 基本用法

```jsx
import { Steps } from 'zarm-web';

ReactDOM.render(
  <>
    <Steps>
      <Steps.Item title="步骤1" description="步骤1描述文案" />
      <Steps.Item title="步骤2" description="步骤2描述文案" />
      <Steps.Item title="步骤3" description="步骤3描述文案" />
      <Steps.Item title="步骤4" />
    </Steps>
  </>, mountNode);
```

## 竖直方向

```jsx
import { Steps } from 'zarm-web';

ReactDOM.render(
  <>
    <Steps direction="vertical">
      <Steps.Item title="步骤1" description="步骤1描述文案" />
      <Steps.Item title="步骤2" description="步骤2描述文案" />
      <Steps.Item title="步骤3" description="步骤3描述文案" />
      <Steps.Item title="步骤4" />
    </Steps>
  </>, mountNode);
```

## 状态

```jsx
import { Steps } from 'zarm-web';

ReactDOM.render(
  <>
    <Steps current={2} status="error">
      <Steps.Item title="步骤1" description="步骤1描述文案" />
      <Steps.Item title="步骤2" disabled description="步骤2描述文案" />
      <Steps.Item title="步骤3" description="步骤3描述文案" />
      <Steps.Item title="步骤4" />
    </Steps>
  </>, mountNode);
```

## 点击事件

```jsx
import { Steps } from 'zarm-web';

class StepsDemo extends React.Component {
  state = {
    current: 0,
  };

  onChange = current => {
    console.log('onChange:', current);
    this.setState({ current });
  };

  render() {
    const { current } = this.state;

    return (
      <>
        <Steps current={current} onChange={this.onChange}>
          <Steps.Item title="步骤1" description="步骤1描述文案" />
          <Steps.Item title="步骤2" disabled description="步骤2描述文案" />
          <Steps.Item title="步骤3" description="步骤3描述文案" />
          <Steps.Item title="步骤4" />
        </Steps>
      </>
    );
  }
}

ReactDOM.render(<StepsDemo />, mountNode);
```
