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。

• 标准线条式页签，用于容器内部的主功能切换，这是最常用的 Tabs。

• RadioButton 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.TabPane;
function callback(key) {
  console.log(key);
}
ReactDOM.render(
  <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>,
  mountNode,
);

禁用

禁用某一项。

import { Tabs } from 'antd';
const TabPane = Tabs.TabPane;
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,
);

图标

有图标的标签。

import { Tabs, Icon } from 'antd';
const TabPane = Tabs.TabPane;
ReactDOM.render(
  <Tabs defaultActiveKey="2">
    <TabPane
      tab={
        <span>
          <Icon type="apple" />
          Tab 1
        </span>
      }
      key="1"
    >
      Tab 1
    </TabPane>
    <TabPane
      tab={
        <span>
          <Icon type="android" />
          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.TabPane;
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 }}>
          <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>
          <TabPane tab="Tab 4" key="4">
            Content of tab 4
          </TabPane>
          <TabPane tab="Tab 5" key="5">
            Content of tab 5
          </TabPane>
          <TabPane tab="Tab 6" key="6">
            Content of tab 6
          </TabPane>
          <TabPane tab="Tab 7" key="7">
            Content of tab 7
          </TabPane>
          <TabPane tab="Tab 8" key="8">
            Content of tab 8
          </TabPane>
          <TabPane tab="Tab 9" key="9">
            Content of tab 9
          </TabPane>
          <TabPane tab="Tab 10" key="10">
            Content of tab 10
          </TabPane>
          <TabPane tab="Tab 11" key="11">
            Content of tab 11
          </TabPane>
        </Tabs>
      </div>
    );
  }
}
ReactDOM.render(<SlidingTabsDemo />, mountNode);

附加内容

可以在页签右边添加附加操作。

import { Tabs, Button } from 'antd';
const TabPane = Tabs.TabPane;
const operations = <Button>Extra Action</Button>;
ReactDOM.render(
  <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>,
  mountNode,
);

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}>
          <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>
      </div>
    );
  }
}
ReactDOM.render(<Demo />, mountNode);

位置

有四个位置，tabPosition="left|right|top|bottom"。

import { Tabs, Select } from 'antd';
const TabPane = Tabs.TabPane;
const Option = Select.Option;
class Demo extends React.Component {
  state = {
    tabPosition: 'top',
  };
  changeTabPosition = tabPosition => {
    this.setState({ tabPosition });
  };
  render() {
    return (
      <div>
        <div style={{ marginBottom: 16 }}>
          Tab position：
          <Select
            value={this.state.tabPosition}
            onChange={this.changeTabPosition}
            dropdownMatchSelectWidth={false}
          >
            <Option value="top">top</Option>
            <Option value="bottom">bottom</Option>
            <Option value="left">left</Option>
            <Option value="right">right</Option>
          </Select>
        </div>
        <Tabs tabPosition={this.state.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>
      </div>
    );
  }
}
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.TabPane;
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.TabPane;
class Demo extends React.Component {
  constructor(props) {
    super(props);
    this.newTabIndex = 0;
    const panes = [
      { 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,
      },
    ];
    this.state = {
      activeKey: panes[0].key,
      panes,
    };
  }
  onChange = activeKey => {
    this.setState({ activeKey });
  };
  onEdit = (targetKey, action) => {
    this[action](targetKey);
  };
  add = () => {
    const panes = this.state.panes;
    const activeKey = `newTab${this.newTabIndex++}`;
    panes.push({ title: 'New Tab', content: 'Content of new Tab', key: activeKey });
    this.setState({ panes, activeKey });
  };
  remove = targetKey => {
    let activeKey = this.state.activeKey;
    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 (
      <Tabs
        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} 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.TabPane;
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 > .ant-tabs-card > .ant-tabs-content {
  height: 120px;
  margin-top: -16px;
}
.card-container > .ant-tabs-card > .ant-tabs-content > .ant-tabs-tabpane {
  background: #fff;
  padding: 16px;
}
.card-container > .ant-tabs-card > .ant-tabs-bar {
  border-color: #fff;
}
.card-container > .ant-tabs-card > .ant-tabs-bar .ant-tabs-tab {
  border-color: transparent;
  background: transparent;
}
.card-container > .ant-tabs-card > .ant-tabs-bar .ant-tabs-tab-active {
  border-color: #fff;
  background: #fff;
}

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.TabPane;
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.panes;
    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.activeKey;
    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.TabPane;
const renderTabBar = (props, DefaultTabBar) => (
  <Sticky bottomOffset={80}>
    {({ style }) => (
      <DefaultTabBar {...props} style={{ ...style, zIndex: 1, background: '#fff' }} />
    )}
  </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,
);

可拖拽标签

使用 react-dnd 实现标签可拖拽。

import { Tabs } from 'antd';
import { DragDropContextProvider, DragSource, DropTarget } from 'react-dnd';
import HTML5Backend from 'react-dnd-html5-backend';
const TabPane = Tabs.TabPane;
// 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 (
      <DragDropContextProvider backend={HTML5Backend}>
        <Tabs renderTabBar={this.renderTabBar} {...this.props}>
          {orderTabs}
        </Tabs>
      </DragDropContextProvider>
    );
  }
}
ReactDOM.render(
  <DraggableTabs>
    <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>
  </DraggableTabs>,
  mountNode,
);
