我如何过滤 Antd 中的列

Question

我正在尝试根据输入过滤数组。 但由于某种原因，这不起作用......

我使用 React 并使用 Antd（Ant Design）依赖项。 React 版本是 16.9.0，Antd 版本是 3.23.1。 我使用反应挂钩来创建站点。

import React, { useState, useEffect } from 'react'
import { Link } from 'react-router-dom'
import { Input, Icon, Button } from 'antd'
import Highlighter from 'react-highlight-words'
import { Button as ButtonCustom, message, HttpRequest, Icon as IconCustom, Table, Footer, Menu, formatDate, store } from '~/routes'

const Permission = props => {

    const [permission, setPermission] = useState([])

    const [searchText, setSearchText] = useState('')

    const [searchInput, setSearchInput] = useState('')

    const handleSearch = (selectedKeys, confirm) => {
        confirm()
        setSearchText(selectedKeys[0])
    }

    const handleReset = clearFilters => {
        clearFilters()
        setSearchText('')
    }

    const getColumnSearchProps = (dataIndex, name) => ({
        filterDropdown: ({ setSelectedKeys, selectedKeys, confirm, clearFilters }) => (
            <div style={{ padding: 8 }}>
                <Input
                    ref={node => { setSearchInput(node) }}
                    placeholder={`Buscar ${name}`}
                    value={selectedKeys[0]}
                    onChange={e => setSelectedKeys(e.target.value ? [e.target.value] : [])}
                    onPressEnter={() => handleSearch(selectedKeys, confirm)}
                    style={{ width: 188, marginBottom: 8, display: 'block' }}
                />
                <Button
                    type="primary"
                    onClick={() => handleSearch(selectedKeys, confirm)}
                    icon="search"
                    size="small"
                    style={{ width: 90, marginRight: 8 }}
                >
                    Buscar
                </Button>
                <Button onClick={() => handleReset(clearFilters)} size="small" style={{ width: 90 }}>
                    Limpar
                </Button>
            </div>
        ),
        filterIcon: filtered => (
            <Icon type="search" style={{ color: filtered ? '#1890ff' : undefined }} />
        ),
        onFilter: (value, record) =>
            record[dataIndex]
                .toString()
                .toLowerCase()
                .includes(value.toLowerCase()),
        onFilterDropdownVisibleChange: visible => { if (visible) setTimeout(() => searchInput.select()) },
        render: text => (
            <Highlighter
                highlightStyle={{ backgroundColor: '#ffc069', padding: 0 }}
                searchWords={[searchText]}
                autoEscape
                textToHighlight={text.toString()}
            />
        )
    })

    useEffect(() => {
        setPermission(store.getState().states.permissions)
    }, [])

            <ButtonCustom tipo="main" description="Criar uma nova Permissão" handle={() => props.history.push("/createpermission")}>
                Cadastrar permissão
            </ButtonCustom>
            <Footer />
        </>
    )
}

export default Permission

我希望通过输入输入它只会过滤那些具有指定名称的人。 但它显示了错误：

这是我想做的一个例子：正在工作的示例代码

您可能已经找到了解决方案，但希望这对其他人有帮助

我在使用带有 antd 表的钩子时遇到了同样的问题。 this.searchInput变量不应该是 React state 的一部分，这就是它更新太频繁的原因。 使其成为一个简单的变量，如下所示：

let searchInput = null;

...

<Input
    ref={node => { searchInput = node }}
    ...
/>

...

那应该可以解决您的问题
