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。

Choerodon 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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 'choerodon-ui';
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 (lastIndex >= 0 && activeKey === targetKey) {
      activeKey = panes[lastIndex].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 'choerodon-ui';
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);

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 'choerodon-ui';
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 (lastIndex >= 0 && activeKey === targetKey) {
      activeKey = panes[lastIndex].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);
