Tabs标签页

选项卡切换组件。

何时使用

提供平级的区域将大块内容进行收纳和展现，保持界面整洁。

Ant Design 依次提供了三级选项卡，分别用于不同的场景。

• 卡片式的页签，提供可关闭的样式，常用于容器顶部。

• 既可用于容器顶部，也可用于容器内部，是最通用的 Tabs。

• Radio.Button 可作为更次级的页签来使用。

代码演示

基本

默认选中第一项。

import { Tabs } from 'antd';
const { TabPane } = Tabs;
function callback(key) {
  console.log(key);
}
const Demo = () => (
  <Tabs defaultActiveKey="1" onChange={callback}>
    <TabPane tab="Tab 1" key="1">
      Content of Tab Pane 1
    </TabPane>
    <TabPane tab="Tab 2" key="2">
      Content of Tab Pane 2
    </TabPane>
    <TabPane tab="Tab 3" key="3">
      Content of Tab Pane 3
    </TabPane>
  </Tabs>
);
ReactDOM.render(<Demo />, mountNode);

禁用

禁用某一项。

import { Tabs } from 'antd';
const { TabPane } = Tabs;
ReactDOM.render(
  <Tabs defaultActiveKey="1">
    <TabPane tab="Tab 1" key="1">
      Tab 1
    </TabPane>
    <TabPane tab="Tab 2" disabled key="2">
      Tab 2
    </TabPane>
    <TabPane tab="Tab 3" key="3">
      Tab 3
    </TabPane>
  </Tabs>,
  mountNode,
);

居中

标签居中展示。

import { Tabs } from 'antd';
const { TabPane } = Tabs;
const Demo = () => (
  <Tabs defaultActiveKey="1" centered>
    <TabPane tab="Tab 1" key="1">
      Content of Tab Pane 1
    </TabPane>
    <TabPane tab="Tab 2" key="2">
      Content of Tab Pane 2
    </TabPane>
    <TabPane tab="Tab 3" key="3">
      Content of Tab Pane 3
    </TabPane>
  </Tabs>
);
ReactDOM.render(<Demo />, mountNode);

图标

有图标的标签。

import { Tabs } from 'antd';
import { AppleOutlined, AndroidOutlined } from '@ant-design/icons';
const { TabPane } = Tabs;
ReactDOM.render(
  <Tabs defaultActiveKey="2">
    <TabPane
      tab={
        <span>
          <AppleOutlined />
          Tab 1
        </span>
      }
      key="1"
    >
      Tab 1
    </TabPane>
    <TabPane
      tab={
        <span>
          <AndroidOutlined />
          Tab 2
        </span>
      }
      key="2"
    >
      Tab 2
    </TabPane>
  </Tabs>,
  mountNode,
);

滑动

可以左右、上下滑动，容纳更多标签。

import { Tabs, Radio } from 'antd';
const { TabPane } = Tabs;
class SlidingTabsDemo extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      mode: 'top',
    };
  }
  handleModeChange = e => {
    const mode = e.target.value;
    this.setState({ mode });
  };
  render() {
    const { mode } = this.state;
    return (
      <div>
        <Radio.Group onChange={this.handleModeChange} value={mode} style={{ marginBottom: 8 }}>
          <Radio.Button value="top">Horizontal</Radio.Button>
          <Radio.Button value="left">Vertical</Radio.Button>
        </Radio.Group>
        <Tabs defaultActiveKey="1" tabPosition={mode} style={{ height: 220 }}>
          {[...Array.from({ length: 30 }, (v, i) => i)].map(i => (
            <TabPane tab={`Tab-${i}`} key={i} disabled={i === 28}>
              Content of tab {i}
            </TabPane>
          ))}
        </Tabs>
      </div>
    );
  }
}
ReactDOM.render(<SlidingTabsDemo />, mountNode);

附加内容

可以在页签两边添加附加操作。

import { Tabs, Button, Divider, Checkbox } from 'antd';
const { TabPane } = Tabs;
const CheckboxGroup = Checkbox.Group;
const operations = <Button>Extra Action</Button>;
const OperationsSlot = {
  left: <Button className="tabs-extra-demo-button">Left Extra Action</Button>,
  right: <Button>Right Extra Action</Button>,
};
const options = ['left', 'right'];
const Demo = () => {
  const [position, setPosition] = React.useState(['left', 'right']);
  const slot = React.useMemo(() => {
    if (position.length === 0) return null;
    return position.reduce(
      (acc, direction) => ({ ...acc, [direction]: OperationsSlot[direction] }),
      {},
    );
  }, [position]);
  return (
    <>
      <Tabs tabBarExtraContent={operations}>
        <TabPane tab="Tab 1" key="1">
          Content of tab 1
        </TabPane>
        <TabPane tab="Tab 2" key="2">
          Content of tab 2
        </TabPane>
        <TabPane tab="Tab 3" key="3">
          Content of tab 3
        </TabPane>
      </Tabs>
      <br />
      <br />
      <br />
      <div>You can also specify its direction or both side</div>
      <Divider />
      <CheckboxGroup
        options={options}
        value={position}
        onChange={value => {
          setPosition(value);
        }}
      />
      <br />
      <br />
      <Tabs tabBarExtraContent={slot}>
        <TabPane tab="Tab 1" key="1">
          Content of tab 1
        </TabPane>
        <TabPane tab="Tab 2" key="2">
          Content of tab 2
        </TabPane>
        <TabPane tab="Tab 3" key="3">
          Content of tab 3
        </TabPane>
      </Tabs>
    </>
  );
};
ReactDOM.render(<Demo />, mountNode);

.tabs-extra-demo-button {
  margin-right: 16px;
}
.ant-row-rtl .tabs-extra-demo-button {
  margin-right: 0;
  margin-left: 16px;
}

大小

大号页签用在页头区域，小号用在弹出框等较狭窄的容器内。

import { Tabs, Radio } from 'antd';
const { TabPane } = Tabs;
class Demo extends React.Component {
  state = { size: 'small' };
  onChange = e => {
    this.setState({ size: e.target.value });
  };
  render() {
    const { size } = this.state;
    return (
      <div>
        <Radio.Group value={size} onChange={this.onChange} style={{ marginBottom: 16 }}>
          <Radio.Button value="small">Small</Radio.Button>
          <Radio.Button value="default">Default</Radio.Button>
          <Radio.Button value="large">Large</Radio.Button>
        </Radio.Group>
        <Tabs defaultActiveKey="1" size={size} style={{ marginBottom: 32 }}>
          <TabPane tab="Tab 1" key="1">
            Content of tab 1
          </TabPane>
          <TabPane tab="Tab 2" key="2">
            Content of tab 2
          </TabPane>
          <TabPane tab="Tab 3" key="3">
            Content of tab 3
          </TabPane>
        </Tabs>
        <Tabs defaultActiveKey="1" type="card" size={size}>
          <TabPane tab="Card Tab 1" key="1">
            Content of card tab 1
          </TabPane>
          <TabPane tab="Card Tab 2" key="2">
            Content of card tab 2
          </TabPane>
          <TabPane tab="Card Tab 3" key="3">
            Content of card tab 3
          </TabPane>
        </Tabs>
      </div>
    );
  }
}
ReactDOM.render(<Demo />, mountNode);

位置

有四个位置，tabPosition="left|right|top|bottom"。在移动端下，left|right 会自动切换成 top。

import { Tabs, Radio, Space } from 'antd';
const { TabPane } = Tabs;
class Demo extends React.Component {
  state = {
    tabPosition: 'left',
  };
  changeTabPosition = e => {
    this.setState({ tabPosition: e.target.value });
  };
  render() {
    const { tabPosition } = this.state;
    return (
      <>
        <Space style={{ marginBottom: 24 }}>
          Tab position:
          <Radio.Group value={tabPosition} onChange={this.changeTabPosition}>
            <Radio.Button value="top">top</Radio.Button>
            <Radio.Button value="bottom">bottom</Radio.Button>
            <Radio.Button value="left">left</Radio.Button>
            <Radio.Button value="right">right</Radio.Button>
          </Radio.Group>
        </Space>
        <Tabs tabPosition={tabPosition}>
          <TabPane tab="Tab 1" key="1">
            Content of Tab 1
          </TabPane>
          <TabPane tab="Tab 2" key="2">
            Content of Tab 2
          </TabPane>
          <TabPane tab="Tab 3" key="3">
            Content of Tab 3
          </TabPane>
        </Tabs>
      </>
    );
  }
}
ReactDOM.render(<Demo />, mountNode);

卡片式页签

另一种样式的页签，不提供对应的垂直样式。

import { Tabs } from 'antd';
const { TabPane } = Tabs;
function callback(key) {
  console.log(key);
}
ReactDOM.render(
  <Tabs onChange={callback} type="card">
    <TabPane tab="Tab 1" key="1">
      Content of Tab Pane 1
    </TabPane>
    <TabPane tab="Tab 2" key="2">
      Content of Tab Pane 2
    </TabPane>
    <TabPane tab="Tab 3" key="3">
      Content of Tab Pane 3
    </TabPane>
  </Tabs>,
  mountNode,
);

新增和关闭页签

只有卡片样式的页签支持新增和关闭选项。使用 closable={false} 禁止关闭。

import { Tabs } from 'antd';
const { TabPane } = Tabs;
const initialPanes = [
  { title: 'Tab 1', content: 'Content of Tab 1', key: '1' },
  { title: 'Tab 2', content: 'Content of Tab 2', key: '2' },
  {
    title: 'Tab 3',
    content: 'Content of Tab 3',
    key: '3',
    closable: false,
  },
];
class Demo extends React.Component {
  newTabIndex = 0;
  state = {
    activeKey: initialPanes[0].key,
    panes: initialPanes,
  };
  onChange = activeKey => {
    this.setState({ activeKey });
  };
  onEdit = (targetKey, action) => {
    this[action](targetKey);
  };
  add = () => {
    const { panes } = this.state;
    const activeKey = `newTab${this.newTabIndex++}`;
    const newPanes = [...panes];
    newPanes.push({ title: 'New Tab', content: 'Content of new Tab', key: activeKey });
    this.setState({
      panes: newPanes,
      activeKey,
    });
  };
  remove = targetKey => {
    const { panes, activeKey } = this.state;
    let newActiveKey = activeKey;
    let lastIndex;
    panes.forEach((pane, i) => {
      if (pane.key === targetKey) {
        lastIndex = i - 1;
      }
    });
    const newPanes = panes.filter(pane => pane.key !== targetKey);
    if (newPanes.length && newActiveKey === targetKey) {
      if (lastIndex >= 0) {
        newActiveKey = newPanes[lastIndex].key;
      } else {
        newActiveKey = newPanes[0].key;
      }
    }
    this.setState({
      panes: newPanes,
      activeKey: newActiveKey,
    });
  };
  render() {
    const { panes, activeKey } = this.state;
    return (
      <Tabs
        type="editable-card"
        onChange={this.onChange}
        activeKey={activeKey}
        onEdit={this.onEdit}
      >
        {panes.map(pane => (
          <TabPane tab={pane.title} key={pane.key} closable={pane.closable}>
            {pane.content}
          </TabPane>
        ))}
      </Tabs>
    );
  }
}
ReactDOM.render(<Demo />, mountNode);

卡片式页签容器

用于容器顶部，需要一点额外的样式覆盖。

import { Tabs } from 'antd';
const { TabPane } = Tabs;
ReactDOM.render(
  <div className="card-container">
    <Tabs type="card">
      <TabPane tab="Tab Title 1" key="1">
        <p>Content of Tab Pane 1</p>
        <p>Content of Tab Pane 1</p>
        <p>Content of Tab Pane 1</p>
      </TabPane>
      <TabPane tab="Tab Title 2" key="2">
        <p>Content of Tab Pane 2</p>
        <p>Content of Tab Pane 2</p>
        <p>Content of Tab Pane 2</p>
      </TabPane>
      <TabPane tab="Tab Title 3" key="3">
        <p>Content of Tab Pane 3</p>
        <p>Content of Tab Pane 3</p>
        <p>Content of Tab Pane 3</p>
      </TabPane>
    </Tabs>
  </div>,
  mountNode,
);

.card-container p {
  margin: 0;
}
.card-container > .ant-tabs-card .ant-tabs-content {
  height: 120px;
  margin-top: -16px;
}
.card-container > .ant-tabs-card .ant-tabs-content > .ant-tabs-tabpane {
  padding: 16px;
  background: #fff;
}
.card-container > .ant-tabs-card > .ant-tabs-nav::before {
  display: none;
}
.card-container > .ant-tabs-card .ant-tabs-tab,
[data-theme='compact'] .card-container > .ant-tabs-card .ant-tabs-tab {
  background: transparent;
  border-color: transparent;
}
.card-container > .ant-tabs-card .ant-tabs-tab-active,
[data-theme='compact'] .card-container > .ant-tabs-card .ant-tabs-tab-active {
  background: #fff;
  border-color: #fff;
}
#components-tabs-demo-card-top .code-box-demo {
  padding: 24px;
  overflow: hidden;
  background: #f5f5f5;
}
[data-theme='compact'] .card-container > .ant-tabs-card .ant-tabs-content {
  height: 120px;
  margin-top: -8px;
}
[data-theme='dark'] .card-container > .ant-tabs-card .ant-tabs-tab {
  background: transparent;
  border-color: transparent;
}
[data-theme='dark'] #components-tabs-demo-card-top .code-box-demo {
  background: #000;
}
[data-theme='dark'] .card-container > .ant-tabs-card .ant-tabs-content > .ant-tabs-tabpane {
  background: #141414;
}
[data-theme='dark'] .card-container > .ant-tabs-card .ant-tabs-tab-active {
  background: #141414;
  border-color: #141414;
}

自定义新增页签触发器

隐藏默认的页签增加图标，给自定义触发器绑定事件。

import { Tabs, Button } from 'antd';
const { TabPane } = Tabs;
class Demo extends React.Component {
  constructor(props) {
    super(props);
    this.newTabIndex = 0;
    const panes = [
      { title: 'Tab 1', content: 'Content of Tab Pane 1', key: '1' },
      { title: 'Tab 2', content: 'Content of Tab Pane 2', key: '2' },
    ];
    this.state = {
      activeKey: panes[0].key,
      panes,
    };
  }
  onChange = activeKey => {
    this.setState({ activeKey });
  };
  onEdit = (targetKey, action) => {
    this[action](targetKey);
  };
  add = () => {
    const { panes } = this.state;
    const activeKey = `newTab${this.newTabIndex++}`;
    panes.push({ title: 'New Tab', content: 'New Tab Pane', key: activeKey });
    this.setState({ panes, activeKey });
  };
  remove = targetKey => {
    let { activeKey } = this.state;
    let lastIndex;
    this.state.panes.forEach((pane, i) => {
      if (pane.key === targetKey) {
        lastIndex = i - 1;
      }
    });
    const panes = this.state.panes.filter(pane => pane.key !== targetKey);
    if (panes.length && activeKey === targetKey) {
      if (lastIndex >= 0) {
        activeKey = panes[lastIndex].key;
      } else {
        activeKey = panes[0].key;
      }
    }
    this.setState({ panes, activeKey });
  };
  render() {
    return (
      <div>
        <div style={{ marginBottom: 16 }}>
          <Button onClick={this.add}>ADD</Button>
        </div>
        <Tabs
          hideAdd
          onChange={this.onChange}
          activeKey={this.state.activeKey}
          type="editable-card"
          onEdit={this.onEdit}
        >
          {this.state.panes.map(pane => (
            <TabPane tab={pane.title} key={pane.key}>
              {pane.content}
            </TabPane>
          ))}
        </Tabs>
      </div>
    );
  }
}
ReactDOM.render(<Demo />, mountNode);

自定义页签头

使用 react-sticky 组件实现吸顶效果。

import { Tabs } from 'antd';
import { StickyContainer, Sticky } from 'react-sticky';
const { TabPane } = Tabs;
const renderTabBar = (props, DefaultTabBar) => (
  <Sticky bottomOffset={80}>
    {({ style }) => (
      <DefaultTabBar {...props} className="site-custom-tab-bar" style={{ ...style }} />
    )}
  </Sticky>
);
ReactDOM.render(
  <StickyContainer>
    <Tabs defaultActiveKey="1" renderTabBar={renderTabBar}>
      <TabPane tab="Tab 1" key="1" style={{ height: 200 }}>
        Content of Tab Pane 1
      </TabPane>
      <TabPane tab="Tab 2" key="2">
        Content of Tab Pane 2
      </TabPane>
      <TabPane tab="Tab 3" key="3">
        Content of Tab Pane 3
      </TabPane>
    </Tabs>
  </StickyContainer>,
  mountNode,
);

.site-custom-tab-bar {
  z-index: 1;
  background: #fff;
}

可拖拽标签

使用 react-dnd 实现标签可拖拽。

import { Tabs } from 'antd';
import { DndProvider, DragSource, DropTarget } from 'react-dnd';
import { HTML5Backend } from 'react-dnd-html5-backend';
const { TabPane } = Tabs;
// Drag & Drop node
class TabNode extends React.Component {
  render() {
    const { connectDragSource, connectDropTarget, children } = this.props;
    return connectDragSource(connectDropTarget(children));
  }
}
const cardTarget = {
  drop(props, monitor) {
    const dragKey = monitor.getItem().index;
    const hoverKey = props.index;
    if (dragKey === hoverKey) {
      return;
    }
    props.moveTabNode(dragKey, hoverKey);
    monitor.getItem().index = hoverKey;
  },
};
const cardSource = {
  beginDrag(props) {
    return {
      id: props.id,
      index: props.index,
    };
  },
};
const WrapTabNode = DropTarget('DND_NODE', cardTarget, connect => ({
  connectDropTarget: connect.dropTarget(),
}))(
  DragSource('DND_NODE', cardSource, (connect, monitor) => ({
    connectDragSource: connect.dragSource(),
    isDragging: monitor.isDragging(),
  }))(TabNode),
);
class DraggableTabs extends React.Component {
  state = {
    order: [],
  };
  moveTabNode = (dragKey, hoverKey) => {
    const newOrder = this.state.order.slice();
    const { children } = this.props;
    React.Children.forEach(children, c => {
      if (newOrder.indexOf(c.key) === -1) {
        newOrder.push(c.key);
      }
    });
    const dragIndex = newOrder.indexOf(dragKey);
    const hoverIndex = newOrder.indexOf(hoverKey);
    newOrder.splice(dragIndex, 1);
    newOrder.splice(hoverIndex, 0, dragKey);
    this.setState({
      order: newOrder,
    });
  };
  renderTabBar = (props, DefaultTabBar) => (
    <DefaultTabBar {...props}>
      {node => (
        <WrapTabNode key={node.key} index={node.key} moveTabNode={this.moveTabNode}>
          {node}
        </WrapTabNode>
      )}
    </DefaultTabBar>
  );
  render() {
    const { order } = this.state;
    const { children } = this.props;
    const tabs = [];
    React.Children.forEach(children, c => {
      tabs.push(c);
    });
    const orderTabs = tabs.slice().sort((a, b) => {
      const orderA = order.indexOf(a.key);
      const orderB = order.indexOf(b.key);
      if (orderA !== -1 && orderB !== -1) {
        return orderA - orderB;
      }
      if (orderA !== -1) {
        return -1;
      }
      if (orderB !== -1) {
        return 1;
      }
      const ia = tabs.indexOf(a);
      const ib = tabs.indexOf(b);
      return ia - ib;
    });
    return (
      <DndProvider backend={HTML5Backend}>
