1 字符串转为时间对象——Moment
Moment.js中文网：https://momentjs.cn/docs/#/parsing/。
npm install moment // 安装moment
var moment = require('moment'); // require
moment().format();
2 记账本实例优化
- bin文件夹下www文件：导入MongoDB数据库。
#!/usr/bin/env node
//导入 db 函数
const db = require('../db/db');//调用 db 函数
db(() => {/*** Module dependencies.*/var app = require('../app');var debug = require('debug')('accounts:server');var http = require('http');...
})
- AccountModel.js：
//导入 mongoose
const mongoose = require('mongoose');
//创建文档的结构对象
//设置集合中文档的属性以及属性值的类型
let AccountSchema = new mongoose.Schema({//标题title: {type: String,required: true},//时间time: Date,//类型type: {type: Number,default: -1},//金额account: {type: Number,required: true},//备注remarks: {type: String }
});//创建模型对象 对文档操作的封装对象
let AccountModel = mongoose.model('accounts', AccountSchema);//暴露模型对象
module.exports = AccountModel;
- Index.js
var express = require('express');
var router = express.Router();
//导入 lowdb
const low = require('lowdb')
const FileSync = require('lowdb/adapters/FileSync')
const adapter = new FileSync(__dirname + '/../data/db.json');
//获取 db 对象
const db = low(adapter);
//导入 shortid
const shortid = require('shortid');
//导入 moment
const moment = require('moment');
const AccountModel = require('../models/AccountModel');//测试
// console.log(moment('2023-02-24').toDate())
//格式化日期对象
// console.log(moment(new Date()).format('YYYY-MM-DD'));//记账本的列表
router.get('/account', function(req, res, next) {//获取所有的账单信息// let accounts = db.get('accounts').value();//读取集合信息AccountModel.find().sort({time: -1}).exec((err, data) => {if(err){res.status(500).send('读取失败~~~');return;}//响应成功的提示res.render('list', {accounts: data, moment: moment});})
});//添加记录
router.get('/account/create', function(req, res, next) {res.render('create');
});//新增记录
router.post('/account', (req, res) => {//查看表单数据 2024-06-06 => new Date()//2024-06-06 => moment => new Date()//console.log(req.body);//修改 req.body.time 的值//req.body.time = moment(req.body.time).toDate();//插入数据库AccountModel.create({...req.body, // ES6语法，所有属性的值//修改 time 属性的值time: moment(req.body.time).toDate()}, (err, data) => {if(err){res.status(500).send('插入失败~~');return}//成功提醒res.render('success', {msg: '添加成功哦~~~', url: '/account'});})
});//删除记录
router.get('/account/:id', (req, res) => {//获取 params 的 id 参数let id = req.params.id;//删除AccountModel.deleteOne({_id: id}, (err, data) => {if(err) {res.status(500).send('删除失败~');return;}//提醒res.render('success', {msg: '删除成功~~~', url: '/account'});})
});module.exports = router;
