當我將道具傳遞給它時，我有一個默認值為 null 的選擇菜單，它會重新渲染新道具作為默認值這是我的選擇組件：import React, { useState, useEffect } from "react"; import Select from "react-select"; class SelectMenu extends React.Component { state = {  defaultValues: [],  }; componentWillReceiveProps(newProps) {  this.setState({ defaultValues: newProps.defaultValue });  }  render() { return (  <Select    options={this.props.options}    closeMenuOnSelect={this.props.closeMenuOnSelect}    components={this.props.components}    isMulti={this.props.isMulti}    onChange={(e) => this.props.onChange(e, this.props.nameOnState)}    placeholder={this.props.default}    defaultValue={this.state.defaultValues}  />  ); }   } export default SelectMenu;
