React And Design自定义Pagination分页数量，支持自定义输入、选择、搜索

示例图

• usePageSizeSelect.js

import {useState} from "react";
import Bus from "../../utils/eventBus";

export function usePageSizeSelect() {
    const onInputKeyDown = (e) => {
        const tempVal = e.target.value;
        if (String(e.key) === 'Enter') {
            console.log('output-> key', e.target.value)
            setVal(e.target.value)
            let totalOptions = [
                ...pageOptions,
                {
                    value: `${tempVal}`,
                    label: `${tempVal}条/页`
                }
            ]
            totalOptions.sort((a, b) => parseInt(a.value, 10) - parseInt(b.value, 10));
            setPageOptions(totalOptions)
            Bus.emit('handle-page-size-change', {pageSize: tempVal})
        }
    }
    const handleSelect = (val, option) => {
        setVal(val)
        Bus.emit('handle-page-size-change', {pageSize: val})
    }
    const [val, setVal] = useState('8')
    const [pageOptions, setPageOptions] = useState(
        [
            {
                value: '8',
                label: '8条/页',
            },
            {
                value: '32',
                label: '32条/页',
            },
            {
                value: '64',
                label: '64条/页',
            },
            {
                value: '128',
                label: '128条/页',
            },
            {
                value: '768',
                label: '768条/页',
            },
            {
                value: '1024',
                label: '1024条/页',
            },
        ]
    )
    return {
        onInputKeyDown,
        val,
        setVal,
        pageOptions,
        handleSelect
    }
}

• 【🥑核心组件】PageSizeSelect.tsx

import { Select } from 'antd';
import React from 'react';
import {usePageSizeSelect} from "../../../hooks/keyMan/usePageSizeSelect";

const PageSizeSelect = () => {
    const {
        val,
        setVal,
        onInputKeyDown,
        pageOptions,
        handleSelect
    } = usePageSizeSelect()


    return(
        <Select
            allowClear
            showSearch
            defaultValue="8"
            size={'middle'}
            style={{ width: 160, marginBottom: 0,}}
            placeholder="请输入分页数"
            getPopupContainer={((triggerNode: any) => triggerNode.parentElement) as any}
            value={val}
            optionFilterProp="label"
            onInputKeyDown={e=> onInputKeyDown(e)}
            options={pageOptions}
            onSelect={handleSelect}
        />
    )
}

export default PageSizeSelect;

• PageSizeSelect组件和Pagination搭配使用

                    <div style={{display: 'flex', justifyContent: 'flex-end', alignItems: 'center'}}>
                        <span>
                            <Pagination
                                current={pageNo}
                                pageSize={pageSize}
                                total={pageTotal}
                                showQuickJumper
                                onChange={onPaging}
                                onShowSizeChange={onPagingSizeChange}
                                showTotal={total => `共 ${total} 条`}
                            />
                        </span>
                        <span style={{ marginLeft: '14px', marginTop: '12px' }}>
                            <PageSizeSelect/>
                        </span>
                    </div>
