ReactSelect渲染自定义组件

Question

我在我的一种形式中使用ReactSelect：

<Select name='event-title' className="event-title" ref="stateSelect" autofocus optionsComponent={DropdownOptions} onInputChange={this.handleChangeTitle} options={this.state.titleResults} simpleValue clearable={this.state.clearable} name="selected-state"  value={this.state.selectedTitleValue} onChange={this.handleTitleChosen} searchable={this.state.searchable} />

我想要呈现自定义optionsComponent：

optionsComponent={DropdownOptions}

通过查看example，您可以渲染自定义组件，因此我对其进行了测试：

const DropdownOptions = React.createClass({
    propTypes: {
        children: React.PropTypes.node,
        className: React.PropTypes.string,
        isDisabled: React.PropTypes.bool,
        isFocused: React.PropTypes.bool,
        isSelected: React.PropTypes.bool,
        onFocus: React.PropTypes.func,
        onSelect: React.PropTypes.func,
        option: React.PropTypes.object.isRequired,
    },
    handleMouseDown (event) {
        event.preventDefault();
        event.stopPropagation();
        this.props.onSelect(this.props.option, event);
    },
    handleMouseEnter (event) {
        this.props.onFocus(this.props.option, event);
    },
    handleMouseMove (event) {
        if (this.props.isFocused) return;
        this.props.onFocus(this.props.option, event);
    },
    render () {
        return (
            <div className={this.props.className}
                onMouseDown={this.handleMouseDown}
                onMouseEnter={this.handleMouseEnter}
                onMouseMove={this.handleMouseMove}
                title={this.props.option.title}>
                <span>Testing Text</span>
                {this.props.children}
            </div>
        );
    }
});

这应该在每个孩子面前呈现<span>Testing Text</span>。但事实并非如此。我做错了什么？

我的最终目标是让我的选项显示如下所示的各种数据：

Answer 1

您写的属性为optionComponent而不是optionsComponent。

Answer 2

使用反应选择V2 ，您可以通过访问传递到自定义组件的data道具和传递给{{1 }}

components

Answer 3

通过升级 react-select V2 及更高版本，您可以通过访问传递给自定义组件的prop以及传递给组件 <Select />的道具，因此您仍然可以保持选择组件的默认行为

import React from 'react';
import { css } from 'emotion';
import Select from 'react-select';
import { colourOptions } from '../data';

const Option = (props: OptionProps) => {
  const {
    children,
    className,
    cx,
    getStyles,
    isDisabled,
    isFocused,
    isSelected,
    innerRef,
    innerProps,
  } = props;
  return (
    <div
      ref={innerRef}
      className={cx(
        css(getStyles('option', props)),
        {
          option: true,
          'option--is-disabled': isDisabled,
          'option--is-focused': isFocused,
          'option--is-selected': isSelected,
        },
        className
      )}
      {...innerProps}
    >
      {children}
    </div>
  );
};

export default () => (
  <Select
    closeMenuOnSelect={false}
    components={{ Option }}
    styles={{
      option: base => ({
        ...base,
        border: `1px dotted ${colourOptions[2].color}`,
        height: '100%',
      }),
    }}
    defaultValue={colourOptions[4]}
    options={colourOptions}
  />
);
