react+antd分页 实现分页及页面刷新时回到刷新前的page

antd框架地址:https://ant.design/index-cn

利用antdUI框架做了个分页,其他功能都没问题,但是页面跳转后刷新会回到第一页,经过学习,在组件里增加了hash值,详情请看代码,实现了页面跳转后刷新依然显示刷新前的页面。

import React from 'react'
import { Pagination, Spin } from 'antd'  //引入分页组件
import 'whatwg-fetch'
import './agricultural.less'

class Agricultural extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      agriculturalList: [],
      currentData: [],
      total: 0,
      pageSize: 3,
      pageNumber: parseInt(window.location.hash.slice(1), 0) || 1 //获取当前页面的hash值,转换为number类型
    }
    // 在react中点击事件里面 setState 时会使this重新定义,所以在点击的函数里面使用this.setState()时会报错this.setState not a function,因此需要提前给点击事件的函数绑定this
    this.onPageChange = this.onPageChange.bind(this);
    this.createMarkup = this.createMarkup.bind(this);
  }
  componentDidMount() {
    this.handleAnchor() //页面刷新时回到刷新前的page
  }
  handleAnchor() {
    this.onPageChange(this.state.pageNumber, this.state.pageSize); //手动调用onPageChange,传入当前页数和每页条数
  }
  
  onPageChange(page, pageSize) {
    this.setState({
      pageNumber: page
    }, () => {
      window.location.hash = `#${page}`; //设置当前页面的hash值为当前page页数
    })
  }

  render() {
    const agriculturalListData = this.state.currentData;return (
        <div className="agricultural-layout">
         // 你要显示的数据内容

//分页实现

<div className="pagination">
<Pagination
className="pagination-com"
showQuickJumper
hideOnSinglePage={ true }
defaultCurrent={ this.state.pageNumber }
current={ this.state.pageNumber }
total={ this.state.total }
pageSize={ this.state.pageSize }
onChange={ this.onPageChange }
showTotal={ (e) => {
return "Total " + e + " items"
} } />
</div>
</div>


</div> ) } } export default Agricultural;
