Mentions提及

提及组件。

何时使用

用于在输入中提及某人或某事，常用于发布、聊天或评论功能。

5.1.0 用法升级

在 5.1.0 版本后，我们提供了 <Mentions options={[...]} /> 的简写方式，有更好的性能和更方便的数据组织方式，开发者不再需要自行拼接 JSX。同时我们废弃了原先的写法，你还是可以在 5.x 继续使用，但会在控制台看到警告，并会在 6.0 后移除。

// >=5.1.0 可用，推荐的写法 ✅
const options = [{ value: 'sample', label: 'sample' }];
return <Mentions options={options} />;

// <5.1.0 可用，>=5.1.0 时不推荐 🙅🏻‍♀️
return (
  <Mentions onChange={onChange}>
    <Mentions.Option value="sample">Sample</Mentions.Option>
  </Mentions>
);

基本使用

基本使用。

TypeScript
JavaScript
import React from 'react';
import { Mentions } from 'antd';
import type { MentionsOptionProps } from 'antd/es/mentions';

const onChange = (value: string) => {
  console.log('Change:', value);
};

const onSelect = (option: MentionsOptionProps) => {
  console.log('select', option);
};

const App: React.FC = () => (
  <Mentions
    style={{ width: '100%' }}
    onChange={onChange}
    onSelect={onSelect}
    defaultValue="@afc163"
    options={[
      {
        value: 'afc163',
        label: 'afc163',
      },
      {
        value: 'zombieJ',
        label: 'zombieJ',
      },
      {
        value: 'yesmeck',
        label: 'yesmeck',
      },
    ]}
  />
);

export default App;

配合 Form 使用

受控模式，例如配合 Form 使用。

TypeScript
JavaScript
import { Button, Form, Mentions, Space } from 'antd';
import React from 'react';

const { getMentions } = Mentions;

const App: React.FC = () => {
  const [form] = Form.useForm();

  const onReset = () => {
    form.resetFields();
  };

  const onFinish = async () => {
    try {
      const values = await form.validateFields();
      console.log('Submit:', values);
    } catch (errInfo) {
      console.log('Error:', errInfo);
    }
  };

  const checkMention = async (_: any, value: string) => {
    const mentions = getMentions(value);

    if (mentions.length < 2) {
      throw new Error('More than one must be selected!');
    }
  };

  return (
    <Form form={form} layout="horizontal" onFinish={onFinish}>
      <Form.Item
        name="coders"
        label="Top coders"
        labelCol={{ span: 6 }}
        wrapperCol={{ span: 16 }}
        rules={[{ validator: checkMention }]}
      >
        <Mentions
          rows={1}
          options={[
            {
              value: 'afc163',
              label: 'afc163',
            },
            {
              value: 'zombieJ',
              label: 'zombieJ',
            },
            {
              value: 'yesmeck',
              label: 'yesmeck',
            },
          ]}
        />
      </Form.Item>
      <Form.Item
        name="bio"
        label="Bio"
        labelCol={{ span: 6 }}
        wrapperCol={{ span: 16 }}
        rules={[{ required: true }]}
      >
        <Mentions
          rows={3}
          placeholder="You can use @ to ref user here"
          options={[
            {
              value: 'afc163',
              label: 'afc163',
            },
            {
              value: 'zombieJ',
              label: 'zombieJ',
            },
            {
              value: 'yesmeck',
              label: 'yesmeck',
            },
          ]}
        />
      </Form.Item>
      <Form.Item wrapperCol={{ span: 14, offset: 6 }}>
        <Space wrap>
          <Button htmlType="submit" type="primary">
            Submit
          </Button>
          <Button htmlType="button" onClick={onReset}>
            Reset
          </Button>
        </Space>
      </Form.Item>
    </Form>
  );
};

export default App;

无效或只读

通过 disabled 属性设置是否生效。通过 readOnly 属性设置是否只读。

TypeScript
JavaScript
import React from 'react';
import { Mentions } from 'antd';

const options = ['afc163', 'zombiej', 'yesmeck'].map((value) => ({
  value,
  key: value,
  label: value,
}));

const App: React.FC = () => (
  <>
    <div style={{ marginBottom: 10 }}>
      <Mentions
        style={{ width: '100%' }}
        placeholder="this is disabled Mentions"
        disabled
        options={options}
      />
    </div>
    <Mentions
      style={{ width: '100%' }}
      placeholder="this is readOnly Mentions"
      readOnly
      options={options}
    />
  </>
);

export default App;

自动大小

自适应内容高度。

TypeScript
JavaScript
import React from 'react';
import { Mentions } from 'antd';

const App: React.FC = () => (
  <Mentions
    autoSize
    style={{ width: '100%' }}
    options={[
      {
        value: 'afc163',
        label: 'afc163',
      },
      {
        value: 'zombieJ',
        label: 'zombieJ',
      },
      {
        value: 'yesmeck',
        label: 'yesmeck',
      },
    ]}
  />
);

export default App;

异步加载

匹配内容列表为异步返回时。

TypeScript
JavaScript
import React, { useCallback, useRef, useState } from 'react';
import { Mentions } from 'antd';
import debounce from 'lodash/debounce';

const App: React.FC = () => {
  const [loading, setLoading] = useState(false);
  const [users, setUsers] = useState<{ login: string; avatar_url: string }[]>([]);
  const ref = useRef<string>();

  const loadGithubUsers = (key: string) => {
    if (!key) {
      setUsers([]);
      return;
    }

    fetch(`https://api.github.com/search/users?q=${key}`)
      .then((res) => res.json())
      .then(({ items = [] }) => {
        if (ref.current !== key) return;

        setLoading(false);
        setUsers(items.slice(0, 10));
      });
  };

  const debounceLoadGithubUsers = useCallback(debounce(loadGithubUsers, 800), []);

  const onSearch = (search: string) => {
    console.log('Search:', search);
    ref.current = search;
    setLoading(!!search);
    setUsers([]);

    debounceLoadGithubUsers(search);
  };

  return (
    <Mentions
      style={{ width: '100%' }}
      loading={loading}
      onSearch={onSearch}
      options={users.map(({ login, avatar_url: avatar }) => ({
        key: login,
        value: login,
        className: 'antd-demo-dynamic-option',
        label: (
          <>
            <img src={avatar} alt={login} />
            <span>{login}</span>
          </>
        ),
      }))}
    />
  );
};

export default App;
.antd-demo-dynamic-option img {
  width: 20px;
  height: 20px;
  margin-right: 8px;
}

自定义触发字符

通过 prefix 属性自定义触发字符。默认为 @, 可以定义为数组。

TypeScript
JavaScript
import React, { useState } from 'react';
import { Mentions } from 'antd';

const MOCK_DATA = {
  '@': ['afc163', 'zombiej', 'yesmeck'],
  '#': ['1.0', '2.0', '3.0'],
};

type PrefixType = keyof typeof MOCK_DATA;

const App: React.FC = () => {
  const [prefix, setPrefix] = useState<PrefixType>('@');

  const onSearch = (_: string, newPrefix: PrefixType) => {
    setPrefix(newPrefix);
  };

  return (
    <Mentions
      style={{ width: '100%' }}
      placeholder="input @ to mention people, # to mention tag"
      prefix={['@', '#']}
      onSearch={onSearch}
      options={(MOCK_DATA[prefix] || []).map((value) => ({
        key: value,
        value,
        label: value,
      }))}
    />
  );
};

export default App;

向上展开

向上展开建议。

TypeScript
JavaScript
import React from 'react';
import { Mentions } from 'antd';

const App: React.FC = () => (
  <Mentions
    style={{ width: '100%' }}
    placement="top"
    options={[
      {
        value: 'afc163',
        label: 'afc163',
      },
      {
        value: 'zombieJ',
        label: 'zombieJ',
      },
      {
        value: 'yesmeck',
        label: 'yesmeck',
      },
    ]}
  />
);

export default App;

自定义状态

使用 status 为 Mentions 添加状态。可选 error 或者 warning。

TypeScript
JavaScript
import React from 'react';
import { Mentions, Space } from 'antd';
import type { MentionsOptionProps } from 'antd/es/mentions';

const onChange = (value: string) => {
  console.log('Change:', value);
};

const onSelect = (option: MentionsOptionProps) => {
  console.log('select', option);
};

const App: React.FC = () => {
  const options = [
    {
      value: 'afc163',
      label: 'afc163',
    },
    {
      value: 'zombieJ',
      label: 'zombieJ',
    },
    {
      value: 'yesmeck',
      label: 'yesmeck',
    },
  ];

  return (
    <Space direction="vertical">
      <Mentions
        onChange={onChange}
        onSelect={onSelect}
        defaultValue="@afc163"
        status="error"
        options={options}
      />
      <Mentions
        onChange={onChange}
        onSelect={onSelect}
        defaultValue="@afc163"
        status="warning"
        options={options}
      />
    </Space>
  );
};

export default App;
