环境搭建
使用CRA创建项目,并安装必要依赖,包括下列基础包
- Redux状态管理 - @reduxjs/toolkit 、 react-redux
- 路由 - react-router-dom
- 时间处理 - dayjs
- class类名处理 - classnames
- 移动端组件库 - antd-mobile
- 请求插件 - axios
pnpm i @reduxjs/toolkit react-redux react-router-dom classname dayjs antd-mobile axios
配置别名路径
1. 背景知识
- 路径解析配置(webpack),把 @/ 解析为 src/
- 路径联想配置(VsCode),VsCode 在输入 @/ 时,自动联想出来对应的 src/下的子级目录
2. 路径解析配置
配置步骤:
- 安装craco
npm i -D @craco/craco - 项目根目录下创建配置文件
craco.config.js - 配置文件中添加路径解析配置
- 包文件中配置启动和打包命令
const path = require("path");
module.exports = {
webpack: {
alias: {
"@": path.resolve(__dirname, "src"),
},
},
};
3. 联想路径配置
针对Vscode的配置
配置步骤:
- 根目录下新增配置文件 - jsconfig.json
- 添加路径提示配置
{
"compilerOptions":{
"baseUrl":"./",
"paths":{
"@/*":[
"src/*"
]
}
}
}
数据Mock实现
在前后端分类的开发模式下,前端可以在没有实际后端接口的支持下先进行接口数据的模拟,进行正常的业务功能开发
1. 常见的Mock方式
2. json-server实现Mock
实现步骤:
- 项目中安装json-server
npm i -D json-server - 准备一个json文件 (素材里获取)
server / data.json
{
"ka": [
{
"type": "pay",
"money": -99,
"date": "2022-10-24 10:36:42",

}
]
}
- 添加启动命令
"serve": "json-serve ./serve/data.json --port 8888"
- 访问接口进行测试
http://localhost:8888/ka
整体路由设计
俩个一级路由 (Layout / new)
俩个二级路由 (Layout - mouth/year)
步骤:
- Views 里面写简单的页面
const Month = () => {
return <div>Month</div>;
};
export default Month;
- router / index.js
import Layout from "@/views/Layout";
import Month from "@/views/Month";
import New from "@/views/New";
import Year from "@/views/Year";
import { createBrowserRouter } from "react-router-dom";
const router = createBrowserRouter([
{
path: "/",
element: <Layout />,
children: [
{
path: "month",
element: <Month />,
},
{
path: "year",
element: <Year />,
},
],
},
{
path: "/new",
element: <New />,
},
]);
export default router;
- 注入
根目录 index.js
配置路由的时候App可以不要了
import React from "react";
import ReactDOM from "react-dom/client";
import "./index.css";
// import App from "./App";
import router from "./router";
import { RouterProvider } from "react-router-dom";
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(<RouterProvider router={router} />);
- 到这一步之前 2级路由 不会显示,因为还没配置2级路由出口!!!!
在year 和month的爹添加二级路由出口
import { Outlet } from "react-router-dom";
const Layout = () => {
return (
<div>
layout
<Outlet />
</div>
);
};
export default Layout;
antD主题定制
1. 定制方案
如果是全局就是div里面的Button和外边的Button都会生效;如果是局部的话,只有div里面的button才会变
2. 实现方式
- 创建css 文件
src / theme.css
/* 全局定制 */
:root:root {
--adm-color-primary: skyblue;
}
/* 局部定制 */
.purple {
--adm-color-primary: purple;
}
- 导入 入口文件 index.js
// 导入定制主题
import "./theme.css";
- 使用
import { Outlet } from "react-router-dom";
import { Button } from "antd-mobile";
const Layout = () => {
return (
<div>
layout
{/* 注意这里的不是普通的button */}
<Button color="primary">ceshi</Button>
<div className="purple">
<Button color="primary">jvbu</Button>
</div>
<Outlet />
</div>
);
};
export default Layout;
3. 记账本主题色
:root:root {
--adm-color-primary: rgb(105, 174, 120);
}
Redux管理账目列表
// 账单列表相关store
import { createSlice } from '@reduxjs/toolkit'
import axios from 'axios'
const billStore = createSlice({
name: 'bill',
// 数据状态state
initialState: {
billList: []
},
reducers: {
// 同步修改方法
setBillList (state, action) {
state.billList = action.payload
}
}
})
// 解构actionCreater函数
const { setBillList } = billStore.actions
// 编写异步
const getBillList = () => {
return async (dispatch) => {
// 编写异步请求
const res = await axios.get('http://localhost:8888/ka')
// 触发同步reducer
dispatch(setBillList(res.data))
}
}
export { getBillList }
// 导出reducer
const reducer = billStore.reducer
export default reducer
// 组合子模块 导出store实例
import { configureStore } from '@reduxjs/toolkit'
import billReducer from './modules/billStore'
const store = configureStore({
reducer: {
bill: billReducer
}
})
export default store
入口文件 index.js
import router from './router'
import { Provider } from 'react-redux'
const root = ReactDOM.createRoot(document.getElementById('root'))
root.render(
<Provider store={store}>
<RouterProvider router={router} />
</Provider>
)
TabBar功能实现
1. 静态布局实现
配套静态模版和样式文件
import { TabBar } from "antd-mobile"
import { useEffect } from "react"
import { Outlet } from "react-router-dom"
import { useDispatch } from 'react-redux'
import { getBillList } from "@/store/modules/billStore"
import './index.scss'
import {
BillOutline,
CalculatorOutline,
AddCircleOutline
} from 'antd-mobile-icons'
const tabs = [
{
key: '/month',
title: '月度账单',
icon: <BillOutline />,
},
{
key: '/new',
title: '记账',
icon: <AddCircleOutline />,
},
{
key: '/year',
title: '年度账单',
icon: <CalculatorOutline />,
},
]
const Layout = () => {
const dispatch = useDispatch()
useEffect(() => {
dispatch(getBillList())
}, [dispatch])
return (
<div className="layout">
<div className="container">
<Outlet />
</div>
<div className="footer">
<TabBar>
{tabs.map(item => (
<TabBar.Item key={item.key} icon={item.icon} title={item.title} />
))}
</TabBar>
</div>
</div>
)
}
export default Layout
.layout {
.container {
position: fixed;
top: 0;
bottom: 50px;
}
.footer {
position: fixed;
bottom: 0;
width: 100%;
}
}
下载sass
npm i -D sass
2. 切换路由实现
监听change事件,在事件回调中调用路由跳转方法
// 切换菜单跳转路由
const navigate = useNavigate()
const swithRoute = (path) => {
console.log(path)
navigate(path)
}
return (
<div className="layout">
<div className="footer">
<TabBar onChange={swithRoute}>
{/* 省略... */}
</TabBar>
</div>
</div>
)
月度账单-统计区域
1. 准备静态结构
views / Month / index.js
import { NavBar, DatePicker } from 'antd-mobile'
import './index.scss'
const Month = () => {
return (
<div className="monthlyBill">
<NavBar className="nav" backArrow={false}>
月度收支
</NavBar>
<div className="content">
<div className="header">
{/* 时间切换区域 */}
<div className="date">
<span className="text">
2023 | 3月账单
</span>
<span className='arrow expand'></span>
</div>
{/* 统计区域 */}
<div className='twoLineOverview'>
<div className="item">
<span className="money">{100}</span>
<span className="type">支出</span>
</div>
<div className="item">
<span className="money">{200}</span>
<span className="type">收入</span>
</div>
<div className="item">
<span className="money">{200}</span>
<span className="type">结余</span>
</div>
</div>
{/* 时间选择器 */}
<DatePicker
className="kaDate"
title="记账日期"
precision="month"
visible={false}
max={new Date()}
/>
</div>
</div>
</div >
)
}
export default Month
.monthlyBill {
--ka-text-color: #191d26;
height: 100%;
background: linear-gradient(180deg, #ffffff, #f5f5f5 100%);
background-size: 100% 240px;
background-repeat: no-repeat;
background-color: rgba(245, 245, 245, 0.9);
color: var(--ka-text-color);
.nav {
--adm-font-size-10: 16px;
color: #121826;
background-color: transparent;
.adm-nav-bar-back-arrow {
font-size: 20px;
}
}
.content {
height: 573px;
padding: 0 10px;
overflow-y: scroll;
-ms-overflow-style: none; /* Internet Explorer 10+ */
scrollbar-width: none; /* Firefox */
&::-webkit-scrollbar {
display: none; /* Safari and Chrome */
}
> .header {
height: 135px;
padding: 20px 20px 0px 18.5px;
margin-bottom: 10px;
background-image: url(https://zqran.gitee.io/images/ka/month-bg.png);
background-size: 100% 100%;
.date {
display: flex;
align-items: center;
margin-bottom: 25px;
font-size: 16px;
.arrow {
display: inline-block;
width: 7px;
height: 7px;
margin-top: -3px;
margin-left: 9px;
border-top: 2px solid #121826;
border-left: 2px solid #121826;
transform: rotate(225deg);
transform-origin: center;
transition: all 0.3s;
}
.arrow.expand {
transform: translate(0, 2px) rotate(45deg);
}
}
}
}
.twoLineOverview {
display: flex;
justify-content: space-between;
width: 250px;
.item {
display: flex;
flex-direction: column;
.money {
height: 24px;
line-height: 24px;
margin-bottom: 5px;
font-size: 18px;
}
.type {
height: 14px;
line-height: 14px;
font-size: 12px;
}
}
}
}
2. 点击切换时间选择框
实现思路:
- 准备一个状态数据
- 点击切换状态
- 根据状态控制弹框打开关闭以及箭头样式
import { NavBar, DatePicker } from 'antd-mobile'
import './index.scss'
import { useState } from "react"
import classNames from "classnames"
const Month = () => {
// 控制时间选择器打开关闭
const [dateVisible, setDateVisible] = useState(false)
// 时间选择框确实事件
const dateConfirm = (date) => {
// 关闭弹框
setDateVisible(false)
}
return (
<div className="monthlyBill">
<NavBar className="nav" backArrow={false}>
月度收支
</NavBar>
<div className="content">
<div className="header">
{/* 时间切换区域 */}
<div className="date" onClick={() => setDateVisible(true)}>
{/* 省略.. */}
<span className={classNames('arrow', dateVisible && 'expand')}></span>
</div>
{/* 统计区域 */}
{/* 时间选择器 */}
<DatePicker
className="kaDate"
title="记账日期"
precision="month"
visible={dateVisible}
max={new Date()}
onConfirm={dateConfirm}
/>
</div>
</div>
</div >
)
}
export default Month
onClose是点击蒙层关闭
3. 切换时间显示
实现思路:
- 以当前时间作为默认值
- 在时间切换时完成时间修改
用dayjs实现格式化
import dayjs from "dayjs"
const [currentMonth, setCurrentMonth] = useState(() => {
return dayjs().format('YYYY-MM')
})
const dateConfirm = (date) => {
setDateVisible(false)
const month = dayjs(date).format('YYYY-MM')
setCurrentMonth(month)
}
4. 统计功能实现
实现思路:
- 按月分组
- 根据获取到的时间作为key取当月的账单数组
- 根据当月的账单数组计算支出、收入、总计
1. 按月分组
安装lodash
npm i lodash
使用
import _ from "lodash";
_.groupBy(billList,(item)=>item.data);
const billList = useSelector((state) => state.bill.billList);
const groupList = useMemo(() => {
return _.groupBy(billList, (item) => dayjs(item.date).format("YYYY-MM"));
}, [billList]);
console.log("groupList", groupList);
2. 根据获取到的时间作为key取当月的账单数组
3. 根据当月的账单数组计算支出、收入、总计
const [selectedMonthList, setelectedMonthList] = useState([]);
const monthResult = useMemo(() => {
console.log("monthResult里面的selectedMonthList", selectedMonthList);
let income = selectedMonthList
.filter((item) => item.type === "income")
.reduce((pre, cur) => pre + cur.money, 0);
let pay = selectedMonthList
.filter((item) => item.type === "pay")
.reduce((pre, cur) => pre + cur.money, 0);
console.log(income);
console.log(pay);
return {
pay,
income,
total: pay + income,
};
}, [selectedMonthList]);
4. 初始化时渲染统计数据(一打开页面就计算好当前月份的账单
useEffect(() => {
const nowDate = dayjs().format("YYYY-MM");
// 边界值控制
// 因为是获取数据是异步的,所以 groupList[nowDate] 有可能是空的
if (groupList[nowDate]) {
setelectedMonthList(groupList[nowDate]);
}
}, [groupList]);
// 按月分组
// 注意这里的写法 state.bill.billList
const billList = useSelector(state => state.bill.billList)
const monthGroup = useMemo(() => {
return _.groupBy(billList, item => dayjs(item.date).format('YYYY-MM'))
}, [billList])
// 根据获取到的时间作为key取当月的账单数组
const dateConfirm = (date) => {
const monthKey = dayjs(date).format('YYYY-MM')
setMonthList(monthGroup[monthKey])
}
// 计算统计
const overview = useMemo(() => {
const income = currentMonthList.filter(item => item.type === 'income')
.reduce((a, c) => a + c.money, 0)
const pay = currentMonthList.filter(item => item.type === 'pay')
.reduce((a, c) => a + c.money, 0)
return {
income,
pay,
total: income + pay
}
}, [currentMonthList])

3. 遍历日账单组件并传入参数
{/* 日账单 */}
{dayGroup.dayKeys.map(dayKey => (
<DailyBill key={dayKey} date={dayKey} billList={dayGroup.group[dayKey]} />
))}
4. 接收数据计算统计渲染页面
const DailyBill = ({ date, billList }) => {
const dayResult = useMemo(() => {
// 支出 / 收入 / 结余
const pay = billList.filter(item => item.type === 'pay').reduce((a, c) => a + c.money, 0)
const income = billList.filter(item => item.type === 'income').reduce((a, c) => a + c.money, 0)

1. 渲染基础列表
{/* 单日列表 */}
<div className="billList">
{billList.map(item => {
return (
<div className="bill" key={item.id}>
<div className="detail">
<div className="billType">{item.useFor}</div>
</div>
<div className={classNames('money', item.type)}>
{item.money.toFixed(2)}
</div>
</div>
)
})}
</div>
2. 适配Type
1-准备静态数据
src / contants / index.js
export const billListData = {
pay: [
{
type: 'foods',
name: '餐饮',
list: [
{ type: 'food', name: '餐费' },
{ type: 'drinks', name: '酒水饮料' },
{ type: 'dessert', name: '甜品零食' },
],
},
{
type: 'taxi',
name: '出行交通',
list: [
{ type: 'taxi', name: '打车租车' },
{ type: 'longdistance', name: '旅行票费' },
],
},
{
type: 'recreation',
name: '休闲娱乐',
list: [
{ type: 'bodybuilding', name: '运动健身' },
{ type: 'game', name: '休闲玩乐' },
{ type: 'audio', name: '媒体影音' },
{ type: 'travel', name: '旅游度假' },
],
},
{
type: 'daily',
name: '日常支出',
list: [
{ type: 'clothes', name: '衣服裤子' },
{ type: 'bag', name: '鞋帽包包' },
{ type: 'book', name: '知识学习' },
{ type: 'promote', name: '能力提升' },
{ type: 'home', name: '家装布置' },
],
},
{
type: 'other',
name: '其他支出',
list: [{ type: 'community', name: '社区缴费' }],
},
],
income: [
{
type: 'professional',
name: '其他支出',
list: [
{ type: 'salary', name: '工资' },
{ type: 'overtimepay', name: '加班' },
{ type: 'bonus', name: '奖金' },
],
},
{
type: 'other',
name: '其他收入',
list: [
{ type: 'financial', name: '理财收入' },
{ type: 'cashgift', name: '礼金收入' },
],
},
],
}
// 目的是将 billListData 中的数据转换为一个对象 billTypeToName,然后调用的时候就通过属性名来得到属性值
export const billTypeToName = Object.keys(billListData).reduce((prev, key) => {
billListData[key].forEach(bill => {
bill.list.forEach(item => {
prev[item.type] = item.name
})
})
return prev
}, {})
2-适配type
导入
import { billTypeToName } from "@/contants";
<div className="billType">{billTypeToName[item.useFor]}</div>
月度账单-切换打开关闭
// 声明状态
const [visible, setVisible] = useState(false)
// 控制箭头
<span
className={classNames('arrow', !visible && 'expand')}
onClick={() => setVisible(!visible)}></span>
// 控制列表显示
<div className="billList" style={{ display: !visible && 'none' }}></div>
月度账单-Icon组件封装
src / components / Icon /index.js
1. 准备静态结构
const Icon = () => {
return (
<img
src={`https://yjy-teach-oss.oss-cn-beijing.aliyuncs.com/reactbase/ka/food.svg`}
alt="icon"
style={{
width: 20,
height: 20,
}}
/>
)
}
export default Icon
2. 设计参数
传递参数:
<Icon type={item.useFor}></Icon>
const BASE_URL = 'https://yjy-teach-oss.oss-cn-beijing.aliyuncs.com/reactbase/ka/'
const Icon = ({ type }) => {
return (
<img
src={`${BASE_URL + type}.svg`}
alt="icon"
style={{
width: 20,
height: 20,
}}
/>
)
}
export default Icon
3. 使用组件
<div className="billList" style={{ display: visible ? 'block' : 'none' }}>
{billList.map(item => {
return (
<div className="bill" key={item.id}>
<Icon type={item.useFor} />
</div>
)
})}
</div>

记账 - 支出和收入切换
const new = ()=>{
// 1. 区分账单状态
const [billType, setBillType] = useState('income')
return (
<div className="keepAccounts">
<div className="kaType">
{/* 2. 点击切换状态 */}
<Button
shape="rounded"
className={classNames(billType==='pay'?'selected':'')}
onClick={() => setBillType('pay')}
>
支出
</Button>
<Button
className={classNames(billType==='income'?'selected':'')}
onClick={() => setBillType('income')}
shape="rounded"
>
收入
</Button>
</div>
{/* 2. 适配数据 */}
<div className="kaTypeList">
{billListData[billType].map(item => {
})}
</div>
</div>
)
}
记账 - 新增一笔
1. 组件中收集接口数据
import { useDispatch } from 'react-redux'
const New = () => {
// 收集金额
const [money, setMoney] = useState(0)
const moneyChange = (value) => {
setMoney(value)
}
// 收集账单类型
const [useFor, setUseFor] = useState('')
const dispatch = useDispatch()
// 保存账单
const saveBill = () => {
// 收集表单数据
const data = {
type: billType,
money: billType === 'pay' ? -money : +money,
date: new Date(),
useFor: useFor
}
console.log(data)
dispatch(addBillList(data))
}
return (
<div className="keepAccounts">
<NavBar className="nav" onBack={() => navigate(-1)}>
记一笔
</NavBar>
<div className="header">
<div className="kaType">
<Button
shape="rounded"
className={classNames(billType === 'pay' ? 'selected' : '')}
onClick={() => setBillType('pay')}
>
支出
</Button>
<Button
className={classNames(billType === 'income' ? 'selected' : '')}
shape="rounded"
onClick={() => setBillType('income')}
>
收入
</Button>
</div>
<div className="kaFormWrapper">
<div className="kaForm">
<div className="date">
<Icon type="calendar" className="icon" />
<span className="text">{'今天'}</span>
<DatePicker
className="kaDate"
title="记账日期"
max={new Date()}
/>
</div>
<div className="kaInput">
<Input
className="input"
placeholder="0.00"
type="number"
value={money}
onChange={moneyChange}
/>
<span className="iconYuan">¥</span>
</div>
</div>
</div>
</div>
<div className="kaTypeList">
{/* 数据区域 */}
{billListData[billType].map(item => {
return (
<div className="kaType" key={item.type}>
<div className="title">{item.name}</div>
<div className="list">
{item.list.map(item => {
return (
<div
className={classNames(
'item',
''
)}
key={item.type}
onClick={() => setUseFor(item.type)}
>
<div className="icon">
<Icon type={item.type} />
</div>
<div className="text">{item.name}</div>
</div>
)
})}
</div>
</div>
)
})}
</div>
<div className="btns">
<Button className="btn save" onClick={saveBill}>
保 存
</Button>
</div>
</div>
)
}
export default New
2. 在Redux中编写异步代码
// 同步添加账单方法
addBill(state,action){
state.billList.push(action.payload)
}
//异步请求
const addBillList = (data) => {
return async (dispatch) => {
// 传递data数据
const res = await axios.post("http://localhost:8888/ka", data);
dispatch(addBill(res.data));
};
};
3. 点击保存提交action
import { useDispatch } from "react-redux";
// 点击按钮保存账单
const saveBill = () => {
console.log("money", money);
const data = {
type: billType,
money: billType === "pay" ? -1 * money : money,
data: new Date(),
useFor: type,
};
console.log("data", data);
dispatch(addBillList(data)); // 提交数据
};
4. 选中的图标是激活状态
className={classNames(
"item",
type === item.type && "selected"
)}
key={item.type}
5. 时间选择
6. 如果日期是今天就显示“今天”而不是2024-04-15
const [selectedDate, setSelectedDate] = useState(new Date());<span className="text">
{selectedDate === new Date()
? "今天"
: dayjs(selectedDate).format("YYYY-MM-DD")}
</span>
为什么二者不相等
在 JavaScript 中,两个对象即使它们包含相同的属性和值,但它们引用的内存地址不同,因此它们是不相等的。在这种情况下,selectedDate
是一个 Date
对象,new Date()
创建了一个新的 Date
对象,并且 selectedDate
也是一个 Date
对象,尽管它们的值可能相同,但它们引用的内存地址不同,所以它们是不相等的。
要比较两个日期对象的值是否相等,你应该比较它们的时间戳或者转换为字符串后再进行比较,例如:
selectedDate.getTime() === new Date().getTime()
或者:
selectedDate.toISOString() === new Date().toISOString()
这样可以确保比较的是它们的值而不是引用。
