Reactjs实现通用分页组件的实例代码
作者：远帆时间：2026-10-21 20:40:40浏览：71
本文介绍基于ReactJS开发的通用分页组件，结合Redux状态管理实现数据流控制。通过Webpack打包，展示了前端分页条与后端Go语言数据结构的对接方式，提供完整的组件代码与服务端数据结构定义，适用于需要通用分页功能的Web应用开发。
ReactJS分页组件概述
开发者通常都编写过多种形式的分页工具条，例如纯服务端版本、纯前端JavaScript版本或Angular版本。鉴于这一基础功能在各类应用中广泛存在，下面提供一个基于ReactJS实现的版本。首先通过图片展示其实际运行效果：
开发环境与构建配置
该组件依赖ES6环境，建议配合NodeJS和Webpack进行打包处理，具体命令为：webpack --display-error-details --config webpack.config.js
Redux状态管理集成
建议将此React分页组件与Redux配合使用，以简化开发流程，遵循UI = Fn(State)的设计模式。
基本的数据流转逻辑为：用户交互触发Action，Action由Reducer处理并更新Store，最后Store的变化驱动UI渲染。
掌握上述基础知识至关重要，但这并非本文的核心内容。读者可自行补充相关背景知识，此处不再赘述，直接展示代码实现。
前端组件代码实现
组件文件名为：paging-bar.js
import React, { Component } from 'react'
import Immutable from 'immutable'
import _ from 'lodash'
/* ================================================================================
* React GrxPagingBar 通用分页组件
* author: 天真的好蓝啊
* ================================================================================ */
class GrxPagingBar extends Component {
render() {
var pagingOptions = {
showNumber: 5,
firstText: "<<",
firstTitle: "第一页",
prevText: "<",
prevTitle: "上一页",
beforeTitle: "前",
afterTitle: "后",
pagingTitle: "页",
nextText: ">",
nextTitle: "下一页",
lastText: ">>",
lastTitle: "最后一页",
classNames: "grx-pagingbar pull-right",
}
$.extend(pagingOptions, this.props.pagingOptions)
return (
<div className={pagingOptions.classNames} >
<GrxPagingFirst {...pagingOptions} {...this.props} />
<GrxPagingBeforeAfter isBefore="true" {...pagingOptions} {...this.props} />
<GrxPagingList {...pagingOptions} {...this.props} />
<GrxPagingBeforeAfter isBefore="false" {...pagingOptions} {...this.props} />
<GrxPagingLast {...pagingOptions} {...this.props} />

return (
<span className="grx-pagingbar-fl">

)
}
}
/* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
* 分页条前后页组件

class GrxPagingBeforeAfter extends Component {

}else if(!isBefore && current < pagingCount - this.props.showNumber){
ids.push(1)
}
var html = ids.map(
(v,i) => <a href="###" onClick={this.props.actions.pagingAction.bind(this, pagingIndex)} title={title}>..</a>
)
return (
<span>
{html}
</span>
)
}
}
/* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

class GrxPagingList extends Component {

let count = paging.get('PagingCount')
let current = paging.get('PagingIndex')
let start = current - this.props.showNumber
let end = current + this.props.showNumber
var pageIndexs = new Array();
for(var i = start; i < end; i ++) {
if( i == current){
pageIndexs.push(i)
}else if(i > 0 & i <= count) {
pageIndexs.push(i)
}
}
var pagingList = pageIndexs.map(
(v,i) =>
current == v ?
count > 1 ? <span className="grx-pagingbar-current">{v}</span> : ""
:
<GrxPagingNumber pagingIndex={v} {...this.props} />
)
return(
<span>
{pagingList}
</span>
)
}
}
/* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
* 分页条尾部组件
* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ */
class GrxPagingLast extends Component {
render() {
var ids = []
let paging = this.props.items.get('Paging')
let pagingCount = paging.get('PagingCount')
let current = paging.get('PagingIndex')
let pagingIndex = current + 1
if(paging.get('PagingIndex') < paging.get('PagingCount')){
ids.push(1)
}
let html = ids.map(
(v,i) =>
<span>
<GrxPagingNumber title={this.props.nextTitle} text={this.props.nextText} pagingIndex={pagingIndex} {...this.props}/>
<GrxPagingNumber title={this.props.lastTitle} text={this.props.lastText} pagingIndex={pagingCount} {...this.props} />
</span>
)
return (
<span className="grx-pagingbar-fl">

</span>
)
}
}
/* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

class GrxPagingNumber extends Component {
render(){
let pagingIndex = this.props.pagingIndex
let title = "第"+ pagingIndex + this.props.pagingTitle
let text = pagingIndex
if(this.props.title){
title = this.props.title
}
if(this.props.text){
text = this.props.text
}
return(
<a href="###" onClick={this.props.actions.pagingAction.bind(this, pagingIndex)} title={title}> {text} </a>
)
}
}
/* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
* 分页条信息组件
* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ */
class GrxPagingInfo extends Component {
render() {
let paging = this.props.items.get('Paging')
let pagingIndex = paging.get('PagingIndex')
let pagingCount = paging.get('PagingCount')
let totalRecord = paging.get('TotalRecord')
return (
<span className="grx-pagingbar-info">第{pagingIndex}/{pagingCount}页,共{totalRecord}条数据</span>
)
}
}
/* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
* 从此模块导出分页条组件
* ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ */
export default GrxPagingBar
使用方法：
import React, { Component } from 'react'
import _ from 'lodash'
import classNames from 'classnames'
import PagingBar from '.paging-bar'
/* ================================================================================
* React PagingBar使用范例组件
* ================================================================================ */
class PagingBarExample extends Component {
render() {
let pagingOptions = {
showNumber: 3
}
return (
<table className="table table-condensed">
<tbody>
<tr>
<td>
<PagingBar pagingOptions={pagingOptions} {...this.props} />
</td>
</tr>
</tbody>
</table>
)
}
}后端数据结构定义
以下是Paging分页数据对象的结构定义，对应服务端Go语言的Data Struct：
package commons
import (
"math"
)
type (
Paging struct {
PagingIndex int64
PagingSize int64
TotalRecord int64
PagingCount int64
Sortorder string
}
)
func (paging *Paging) SetTotalRecord(totalRecord int64) {
//paging.PagingIndex = 1
paging.PagingCount = 0
if totalRecord > 0 {
paging.TotalRecord = totalRecord
paging.PagingCount = int64(math.Ceil(float64(paging.TotalRecord) / float64(paging.PagingSize)))
}
}
func (paging *Paging) Offset() int64 {
if paging.PagingIndex <= 1 || paging.PagingSize == 0 {
return 0
}
offset := (paging.PagingIndex * paging.PagingSize) - paging.PagingSize + 1
return offset
}
func (paging *Paging) EndIndex() int64 {
if paging.PagingIndex <= 1 {
return paging.PagingSize
}
offset := paging.PagingIndex * paging.PagingSize
return offset
