Antd 选择搜索框不呈现匹配项 [英] Antd Select Search Box not rendering the matches

问题描述

我有产品数据，我正在使用搜索值过滤数据，然后使用过滤后的数据呈现选项.产品数据来自全球 redux 商店作为道具.出于某种原因，下拉列表仅在搜索值为空时显示数据，当我开始输入时，filteredData 会更新并且组件也会重新渲染，但选项不显示数据.

我已经检查过是否使用了正确的 filteredData 来映射选项.即使重新渲染组件，这些选项似乎也不会渲染.

请看下面的代码:

从'react'导入React；//从 'react' 导入 {useState};从'antd'导入{选择}；从'react-redux'导入{connect}；从'common/actions/fetchData'导入{fetchProductsAsync}；const {选项} = 选择；class SelectOptions 扩展 React.Component {状态 = {过滤数据:[]，值:未定义，};componentDidMount() {const {fetchProductsAsync} = this.props;fetchProductsAsync();const {products} = this.props;this.setState({filteredData: products || []});}componentDidUpdate() {console.log(this.state.filteredData);}filterData = (值) =>{const {products} = this.props;const filData = products.filter((prod) => {返回 prod.name.includes(value);});//console.log(filData);this.setState({filteredData: filData});};handleSearch = (值) =>{const {products} = this.props;如果(值){//this.setState({value});this.filterData(value);//console.log('yes');} 别的 {console.log('空');this.setState({filteredData: products});this.forceUpdate();}};handleChange = (值) =>{//console.log(value);this.setState({value});};使成为() {const {others} = this.props;//console.log(this.state.filteredData);const 选项 = this.state.filteredData.map((item, index) => {控制台日志(项目)；返回 (<选项值={item.value ||item[others.key] ||项目}>{others.customTitle ?(<text style={{fontSize: 13, fontWeight: 'bold'}}>{item[others.customTitle]}</text>) : (item.label ||item[others.key] ||物品)}{others.dataKeys ?(<div className="row";style={{flexWrap: 'wrap'}}>{others.dataKeys.map((i) => (<text style={{fontSize: 11, marginLeft: 5, marginRight: 5}}>{item[i]}</text>))}

) : 空值}</选项>);});返回 (<选择显示搜索onSearch={this.handleSearch}//占位符=选择"//key={this.state.filteredData.length}值={this.state.value}onChange={this.handleChange}>{选项});}}const mapStateToProps = (状态) =>{返回 {产品:state.data.products ||[]};};导出默认连接(mapStateToProps，{fetchProductsAsync})(SelectOptions)；

解决方案

尝试在 Select 组件上设置此道具 filterOption={false}

I have the data of products, and I am filtering the data using a search value and then rendering the options using that filtered data. The products data is coming from the global redux store as a prop. For some reason, the dropdown shows data only when the search value is null, when I start typing, the filteredData is updated and the component get re-rendered as well, but the options show no data.

I have checked whether the right filteredData is used to map over the options. The options does not seem to render even when the component is re-rendered.

Please have a look at the code below :

import React from 'react';
// import {useState} from 'react';
import {Select} from 'antd';
import {connect} from 'react-redux';
import {fetchProductsAsync} from 'common/actions/fetchData';

const {Option} = Select;

class SelectOptions extends React.Component {
  state = {
    filteredData: [],
    value: undefined,
  };

  componentDidMount() {
    const {fetchProductsAsync} = this.props;
    fetchProductsAsync();
    const {products} = this.props;
    this.setState({filteredData: products || []});
  }

  componentDidUpdate() {
    console.log(this.state.filteredData);
  }

  filterData = (value) => {
    const {products} = this.props;
    const filData = products.filter((prod) => {
      return prod.name.includes(value);
    });
    // console.log(filData);
    this.setState({filteredData: filData});
  };

  handleSearch = (value) => {
    const {products} = this.props;
    if (value) {
      // this.setState({value});
      this.filterData(value);
      // console.log('yes');
    } else {
      console.log('empty');
      this.setState({filteredData: products});
      this.forceUpdate();
    }
  };

  handleChange = (value) => {
    // console.log(value);
    this.setState({value});
  };
  render() {
    const {others} = this.props;
    // console.log(this.state.filteredData);
    const options = this.state.filteredData.map((item, index) => {
      console.log(item);
      return (
        <Option value={item.value || item[others.key] || item}>
          {others.customTitle ? (
            <text style={{fontSize: 13, fontWeight: 'bold'}}>{item[others.customTitle]}</text>
          ) : (
            item.label || item[others.key] || item
          )}
          {others.dataKeys ? (
            <div className="row" style={{flexWrap: 'wrap'}}>
              {others.dataKeys.map((i) => (
                <text style={{fontSize: 11, marginLeft: 5, marginRight: 5}}>{item[i]}</text>
              ))}
            </div>
          ) : null}
        </Option>
      );
    });
    return (
      <Select
        showSearch
        onSearch={this.handleSearch}
        // placeholder="Select"
        // key={this.state.filteredData.length}
        value={this.state.value}
        onChange={this.handleChange}>
        {options}
      </Select>
    );
  }
}

const mapStateToProps = (state) => {
  return {products: state.data.products || []};
};

export default connect(mapStateToProps, {fetchProductsAsync})(SelectOptions);

解决方案

Try setting this prop on the Select component filterOption={false}
