Tag 1LinkTag 2Prevent Default

基本

基本标签的用法，可以通过添加 closable 变为可关闭标签。可关闭标签具有 onClose 事件。

import { Tag } from 'antd';

function log(e) {
  console.log(e);
}

function preventDefault(e) {
  e.preventDefault();
  console.log('Clicked! But prevent default.');
}

ReactDOM.render(
  <div>
    <Tag>Tag 1</Tag>
    <Tag>
      <a href="https://github.com/ant-design/ant-design/issues/1862">Link</a>
    </Tag>
    <Tag closable onClose={log}>
      Tag 2
    </Tag>
    <Tag closable onClose={preventDefault}>
      Prevent Default
    </Tag>
  </div>,
  mountNode,
);

UnremovableTag 2Tag 3 New Tag

动态添加和删除

用数组生成一组标签，可以动态添加和删除。

import { Tag, Input, Tooltip, Icon } from 'antd';

class EditableTagGroup extends React.Component {
  state = {
    tags: ['Unremovable', 'Tag 2', 'Tag 3'],
    inputVisible: false,
    inputValue: '',
  };

  handleClose = removedTag => {
    const tags = this.state.tags.filter(tag => tag !== removedTag);
    console.log(tags);
    this.setState({ tags });
  };

  showInput = () => {
    this.setState({ inputVisible: true }, () => this.input.focus());
  };

  handleInputChange = e => {
    this.setState({ inputValue: e.target.value });
  };

  handleInputConfirm = () => {
    const { inputValue } = this.state;
    let { tags } = this.state;
    if (inputValue && tags.indexOf(inputValue) === -1) {
      tags = [...tags, inputValue];
    }
    console.log(tags);
    this.setState({
      tags,
      inputVisible: false,
      inputValue: '',
    });
  };

  saveInputRef = input => (this.input = input);

  render() {
    const { tags, inputVisible, inputValue } = this.state;
    return (
      <div>
        {tags.map((tag, index) => {
          const isLongTag = tag.length > 20;
          const tagElem = (
            <Tag key={tag} closable={index !== 0} onClose={() => this.handleClose(tag)}>
              {isLongTag ? `${tag.slice(0, 20)}...` : tag}
            </Tag>
          );
          return isLongTag ? (
            <Tooltip title={tag} key={tag}>
              {tagElem}
            </Tooltip>
          ) : (
            tagElem
          );
        })}
        {inputVisible && (
          <Input
            ref={this.saveInputRef}
            type="text"
            size="small"
            style={{ width: 78 }}
            value={inputValue}
            onChange={this.handleInputChange}
            onBlur={this.handleInputConfirm}
            onPressEnter={this.handleInputConfirm}
          />
        )}
        {!inputVisible && (
          <Tag onClick={this.showInput} style={{ background: '#fff', borderStyle: 'dashed' }}>
            <Icon type="plus" /> New Tag
          </Tag>
        )}
      </div>
    );
  }
}

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

Categories:MoviesBooksMusicSports

热门标签

选择你感兴趣的话题。

import { Tag } from 'antd';

const { CheckableTag } = Tag;

const tagsFromServer = ['Movies', 'Books', 'Music', 'Sports'];

class HotTags extends React.Component {
  state = {
    selectedTags: [],
  };

  handleChange(tag, checked) {
    const { selectedTags } = this.state;
    const nextSelectedTags = checked ? [...selectedTags, tag] : selectedTags.filter(t => t !== tag);
    console.log('You are interested in: ', nextSelectedTags);
    this.setState({ selectedTags: nextSelectedTags });
  }

  render() {
    const { selectedTags } = this.state;
    return (
      <div>
        <span style={{ marginRight: 8 }}>Categories:</span>
        {tagsFromServer.map(tag => (
          <CheckableTag
            key={tag}
            checked={selectedTags.indexOf(tag) > -1}
            onChange={checked => this.handleChange(tag, checked)}
          >
            {tag}
          </CheckableTag>
        ))}
      </div>
    );
  }
}

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

Tag 1Tag 2Tag 3

New Tag

添加动画

使用 rc-tween-one 给标签增加添加或删除动画。

import { Tag, Input, Icon } from 'antd';
import { TweenOneGroup } from 'rc-tween-one';

class EditableTagGroup extends React.Component {
  state = {
    tags: ['Tag 1', 'Tag 2', 'Tag 3'],
    inputVisible: false,
    inputValue: '',
  };

  handleClose = removedTag => {
    const tags = this.state.tags.filter(tag => tag !== removedTag);
    console.log(tags);
    this.setState({ tags });
  };

  showInput = () => {
    this.setState({ inputVisible: true }, () => this.input.focus());
  };

  handleInputChange = e => {
    this.setState({ inputValue: e.target.value });
  };

  handleInputConfirm = () => {
    const { inputValue } = this.state;
    let { tags } = this.state;
    if (inputValue && tags.indexOf(inputValue) === -1) {
      tags = [...tags, inputValue];
    }
    console.log(tags);
    this.setState({
      tags,
      inputVisible: false,
      inputValue: '',
    });
  };

  saveInputRef = input => (this.input = input);

  forMap = tag => {
    const tagElem = (
      <Tag
        closable
        onClose={e => {
          e.preventDefault();
          this.handleClose(tag);
        }}
      >
        {tag}
      </Tag>
    );
    return (
      <span key={tag} style={{ display: 'inline-block' }}>
        {tagElem}
      </span>
    );
  };

  render() {
    const { tags, inputVisible, inputValue } = this.state;
    const tagChild = tags.map(this.forMap);
    return (
      <div>
        <div style={{ marginBottom: 16 }}>
          <TweenOneGroup
            enter={{
              scale: 0.8,
              opacity: 0,
              type: 'from',
              duration: 100,
              onComplete: e => {
                e.target.style = '';
              },
            }}
            leave={{ opacity: 0, width: 0, scale: 0, duration: 200 }}
            appear={false}
          >
            {tagChild}
          </TweenOneGroup>
        </div>
        {inputVisible && (
          <Input
            ref={this.saveInputRef}
            type="text"
            size="small"
            style={{ width: 78 }}
            value={inputValue}
            onChange={this.handleInputChange}
            onBlur={this.handleInputConfirm}
            onPressEnter={this.handleInputConfirm}
          />
        )}
        {!inputVisible && (
          <Tag onClick={this.showInput} style={{ background: '#fff', borderStyle: 'dashed' }}>
            <Icon type="plus" /> New Tag
          </Tag>
        )}
      </div>
    );
  }
}

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

Presets:

Custom:

多彩标签

我们添加了多种预设色彩的标签样式，用作不同场景使用。如果预设值不能满足你的需求，可以设置为具体的色值。

import { Tag } from 'antd';

ReactDOM.render(
  <div>
    <h4 style={{ marginBottom: 16 }}>Presets:</h4>
    <div>
      <Tag color="magenta">magenta</Tag>
      <Tag color="red">red</Tag>
      <Tag color="volcano">volcano</Tag>
      <Tag color="orange">orange</Tag>
      <Tag color="gold">gold</Tag>
      <Tag color="lime">lime</Tag>
      <Tag color="green">green</Tag>
      <Tag color="cyan">cyan</Tag>
      <Tag color="blue">blue</Tag>
      <Tag color="geekblue">geekblue</Tag>
      <Tag color="purple">purple</Tag>
    </div>
    <h4 style={{ margin: '16px 0' }}>Custom:</h4>
    <div>
      <Tag color="#f50">#f50</Tag>
      <Tag color="#2db7f5">#2db7f5</Tag>
      <Tag color="#87d068">#87d068</Tag>
      <Tag color="#108ee9">#108ee9</Tag>
    </div>
  </div>,
  mountNode,
);
.ant-tag {
  margin-bottom: 8px;
}

可选择

可通过 CheckableTag 实现类似 Checkbox 的效果，点击切换选中效果。

该组件为完全受控组件，不支持非受控用法。

import { Tag } from 'antd';

const { CheckableTag } = Tag;

class MyTag extends React.Component {
  state = { checked: true };

  handleChange = checked => {
    this.setState({ checked });
  };

  render() {
    return (
      <CheckableTag {...this.props} checked={this.state.checked} onChange={this.handleChange} />
    );
  }
}

ReactDOM.render(
  <div>
    <MyTag>Tag1</MyTag>
    <MyTag>Tag2</MyTag>
    <MyTag>Tag3</MyTag>
  </div>,
  mountNode,
);

Movies

控制关闭状态

通过 visible 属性控制关闭状态。

import { Tag, Button } from 'antd';

class Demo extends React.Component {
  state = {
    visible: true,
  };

  render() {
    return (
      <div>
        <Tag
          closable
          visible={this.state.visible}
          onClose={() => this.setState({ visible: false })}
        >
          Movies
        </Tag>
        <br />
        <Button size="small" onClick={() => this.setState({ visible: !this.state.visible })}>
          Toggle
        </Button>
      </div>
    );
  }
}

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