Button按钮

按钮用于开始一个即时操作。

何时使用#

标记了一个(或封装一组)操作命令,响应用户点击行为,触发相应的业务逻辑。

代码演示

按钮有四种类型:主按钮、次按钮、虚线按钮、危险按钮。主按钮在同一个操作区域最多出现一次。

dangerantd@2.7 后支持。

import { Button } from 'antd';

ReactDOM.render(
  <div>
    <Button type="primary">Primary</Button>
    <Button>Default</Button>
    <Button type="dashed">Dashed</Button>
    <Button type="danger">Danger</Button>
  </div>
, mountNode);




按钮有大、中、小三种尺寸。

通过设置 sizelarge small 分别把按钮设为大、小尺寸。若不设置 size,则尺寸为中。

import { Button, Radio, Icon } from 'antd';

class ButtonSize extends React.Component {
  state = {
    size: 'large',
  };

  handleSizeChange = (e) => {
    this.setState({ size: e.target.value });
  }

  render() {
    const size = this.state.size;
    return (
      <div>
        <Radio.Group value={size} onChange={this.handleSizeChange}>
          <Radio.Button value="large">Large</Radio.Button>
          <Radio.Button value="default">Default</Radio.Button>
          <Radio.Button value="small">Small</Radio.Button>
        </Radio.Group>
        <br /><br />
        <Button type="primary" size={size}>Primary</Button>
        <Button size={size}>Normal</Button>
        <Button type="dashed" size={size}>Dashed</Button>
        <Button type="danger" size={size}>Danger</Button>
        <br />
        <Button type="primary" shape="circle" icon="download" size={size} />
        <Button type="primary" icon="download" size={size}>Download</Button>
        <br />
        <Button.Group size={size}>
          <Button type="primary">
            <Icon type="left" />Backward
          </Button>
          <Button type="primary">
            Forward<Icon type="right" />
          </Button>
        </Button.Group>
      </div>
    );
  }
}

ReactDOM.render(<ButtonSize />, mountNode);


添加 loading 属性即可让按钮处于加载状态,最后两个按钮演示点击后进入加载状态。

expand codeexpand code
import { Button } from 'antd';

class App extends React.Component {
  state = {
    loading: false,
    iconLoading: false,
  }

  enterLoading = () => {
    this.setState({ loading: true });
  }

  enterIconLoading = () => {
    this.setState({ iconLoading: true });
  }

  render() {
    return (
      <span>
        <Button type="primary" loading>
          Loading
        </Button>
        <Button type="primary" size="small" loading>
          Loading
        </Button>
        <br />
        <Button type="primary" loading={this.state.loading} onClick={this.enterLoading}>
          Click me!
        </Button>
        <Button type="primary" icon="poweroff" loading={this.state.iconLoading} onClick={this.enterIconLoading}>
          Click me!
        </Button>
        <br />
        <Button shape="circle" loading />
        <Button type="primary" shape="circle" loading />
      </span>
    );
  }
}

ReactDOM.render(<App />, mountNode);

Basic

With Icon

可以将多个 Button 放入 Button.Group 的容器中。

通过设置 sizelarge small 分别把按钮组合设为大、小尺寸。若不设置 size,则尺寸为中。

expand codeexpand code
import { Button, Icon } from 'antd';
const ButtonGroup = Button.Group;

ReactDOM.render(
  <div>
    <h4>Basic</h4>
    <ButtonGroup>
      <Button>Cancel</Button>
      <Button>OK</Button>
    </ButtonGroup>
    <ButtonGroup>
      <Button disabled>L</Button>
      <Button disabled>M</Button>
      <Button disabled>R</Button>
    </ButtonGroup>
    <ButtonGroup>
      <Button>L</Button>
      <Button>M</Button>
      <Button>R</Button>
    </ButtonGroup>

    <h4>With Icon</h4>
    <ButtonGroup>
      <Button type="primary">
        <Icon type="left" />Go back
      </Button>
      <Button type="primary">
        Go forward<Icon type="right" />
      </Button>
    </ButtonGroup>
    <ButtonGroup>
      <Button type="primary" icon="cloud" />
      <Button type="primary" icon="cloud-download" />
    </ButtonGroup>
  </div>,
  mountNode
);

当需要在 Button 内嵌入 Icon 时,可以设置 icon 属性,或者直接在 Button 内使用 Icon 组件。

如果想控制 Icon 具体的位置,只能直接使用 Icon 组件,而非 icon 属性。

expand codeexpand code
import { Button } from 'antd';

ReactDOM.render(
  <div>
    <Button type="primary" shape="circle" icon="search" />
    <Button type="primary" icon="search">Search</Button>
    <Button shape="circle" icon="search" />
    <Button icon="search">Search</Button>
    <br />
    <Button shape="circle" icon="search" />
    <Button icon="search">Search</Button>
    <Button type="dashed" shape="circle" icon="search" />
    <Button type="dashed" icon="search">Search</Button>
  </div>,
  mountNode
);



添加 disabled 属性即可让按钮处于不可用状态,同时按钮样式也会改变。

expand codeexpand code
import { Button } from 'antd';

ReactDOM.render(
  <div>
    <Button type="primary">Primary</Button>
    <Button type="primary" disabled>Primary(disabled)</Button>
    <br />
    <Button>Default</Button>
    <Button disabled>Default(disabled)</Button>
    <br />
    <Button>Ghost</Button>
    <Button disabled>Ghost(disabled)</Button>
    <br />
    <Button type="dashed">Dashed</Button>
    <Button type="dashed" disabled>Dashed(disabled)</Button>
  </div>,
  mountNode
);

按钮组合使用时,推荐使用1个主操作 + n 个次操作,3个以上操作时把更多操作放到 Dropdown.Button 中组合使用。

expand codeexpand code
import { Button, Menu, Dropdown, Icon } from 'antd';

function handleMenuClick(e) {
  console.log('click', e);
}

const menu = (
  <Menu onClick={handleMenuClick}>
    <Menu.Item key="1">1st item</Menu.Item>
    <Menu.Item key="2">2nd item</Menu.Item>
    <Menu.Item key="3">3rd item</Menu.Item>
  </Menu>
);

ReactDOM.render(
  <div>
    <Button type="primary">primary</Button>
    <Button>secondary</Button>
    <Dropdown overlay={menu}>
      <Button>
        Actions <Icon type="down" />
      </Button>
    </Dropdown>
  </div>,
  mountNode
);

幽灵按钮将其他按钮的内容反色,背景变为透明,常用在有色背景上。

expand codeexpand code
import { Button } from 'antd';

ReactDOM.render(
  <div style={{ background: 'rgb(190, 200, 200)', padding: '26px 16px 16px' }}>
    <Button type="primary" ghost>Primary</Button>
    <Button ghost>Default</Button>
    <Button type="dashed" ghost>Dashed</Button>
    <Button type="danger" ghost>danger</Button>
  </div>
, mountNode);

API#

通过设置 Button 的属性来产生不同的按钮样式,推荐顺序为:type -> shape -> size -> loading -> disabled

按钮的属性说明如下:

属性说明类型默认值
ghost幽灵属性,使按钮背景透明,版本 2.7 中增加booleanfalse
htmlType设置 button 原生的 type 值,可选值请参考 HTML 标准stringbutton
icon设置按钮的图标类型string-
loading设置按钮载入状态boolean | { delay: number }false
shape设置按钮形状,可选值为 circle 或者不设string-
size设置按钮大小,可选值为 small large 或者不设stringdefault
type设置按钮类型,可选值为 primary dashed danger(版本 2.7 中增加) 或者不设string-
onClickclick 事件的 handlerfunction-

<Button>Hello world!</Button> 最终会被渲染为 <button><span>Hello world!</span></button>,并且除了上表中的属性,其它属性都会直接传到 <button></button>
