Ant design - 如何在每次选择后自动关闭选择（“标签”或“多个”模式）下拉菜单？

Question

我在页面中使用 ant.design 选择组件（“标签”或“多个”模式），我希望在每次选择后自动关闭下拉菜单。现在它保持打开状态，我应该单击页面中的其他位置以关闭下拉列表。

import { Select } from 'antd';

const { Option } = Select;

function handleChange(value) {
  console.log(`selected ${value}`);
}

ReactDOM.render(
  <Select mode="multiple" placeholder="Select Countries" size="large" onChange={handleChange}>
    <Option value="country1">Country1</Option>
    <Option value="country2">Country2</Option>
    <Option value="country3">Country3</Option>
    <Option value="country4">Country4</Option>
    <Option value="country5">Country5</Option>
    <Option value="country6">Country6</Option>
</Select>,
  mountNode,
);

Answer 1

只需将第一个“选择”组件更改为：

<Select 
      mode="multiple" 
      placeholder="Select Countries"
      size="large" 
      ref={(select) => this.countrySelect = select}
      onChange={()=>{ 
          this.countrySelect.blur()
      }}>
    <Option value="country1">Country1</Option>
    <Option value="country2">Country2</Option>
    <Option value="country3">Country3</Option>
    <Option value="country4">Country4</Option>
    <Option value="country5">Country5</Option>
    <Option value="country6">Country6</Option>
</Select>

来自文档：

import { Select } from 'antd';

const Option = Select.Option;

function handleChange( value ) {
  console.log( `selected ${value}` );
}

<Select defaultValue="lucy" style={ { width: 120 } } onChange={ handleChange }>
  <Option value="jack">Jack</Option>
  <Option value="lucy">Lucy</Option>
  <Option value="disabled" disabled>Disabled</Option>
  <Option value="Yiminghe">yiminghe</Option>
</Select>
<Select defaultValue="lucy" style={ { width: 120 } } disabled>
  <Option value="lucy">Lucy</Option>
</Select>
<Select defaultValue="lucy" style={ { width: 120 } } loading>
    <Option value="lucy">Lucy</Option>
</Select>

使用它自己的<Option>
