How to implement paging query in node

In this example, the related frameworks and templates used include: jade, mongoose, express, layui.

The jade template used at the front desk uses bootstrap layout and layui paging control.
index.jade main code:

//文章列表显示 p.container if(articals.length > 0) p.container.clear - for(var i=0;i
      
index.js main code:
      
var express = require('express'); var mongoose = require('mongoose');require('../models/schema');var article = mongoose.model('Article');var user = mongoose.model('User');var url = require('url');var router = express.Router(); //处理get请求router.get('/', function(req, res, next) { var con = []; article.find({}).exec(function(err, doc){ var total = doc.length; //按时间顺序查找前10条文章的数据 article.find({}).sort({createDate: -1}).populate('creator', 'name').limit(10).exec(function(err, character){ //添加容错措施 if(err){ console.log(err); }else if(character.length == 0){ //没有任何文章，就直接返回 console.log('no articles!'); res.render('index', { title: '首页', articals : con }); }else{ for(var i = 0; i < character.length; i++){ con[i] = { _id: character[i]._id, title: character[i].title, detail: character[i].text.replace(/<[\/]{0,1}[a-zA-Z\s"'=;]{1,}>/g, ''), author: character[i].creator.name, createDate: character[i].createDate }; } //返回文章总数以及前10条数据 res.render('index', { title: '首页', total: total, articals : con }); } }); }) }); //处理带有页码参数的get请求router.get('/index/:page', function(req, res, next) { var con = []; var pageNum = parseInt(req.params.page); var Creator; if(pageNum){ article.find({}).exec(function(err, doc){ var total = doc.length; //按时间顺序查找从第[(页码-1)*10]条数据开始的10条文章的数据 article.find({}).sort({createDate: -1}).populate('creator', 'name').skip((pageNum-1)*10).limit(10).exec(function(err, character){ //添加容错措施 if(err){ console.log(err); }else if(character.length == 0){ console.log('no articles!'); res.render('index', { title: '首页', articals : con }); }else{ for(var i = 0; i < character.length; i++){ con[i] = { _id: character[i]._id, title: character[i].title, detail: character[i].text.replace(/<[\/]{0,1}[a-zA-Z\s"'=;]{1,}>/g, ''), author: character[i].creator.name, createDate: character[i].createDate }; } //返回新的页码以及相应的10条数据 res.render('index', { title: '首页', total: total, page: pageNum, articals : con }); } }); }); } }); module.exports = router;
      
The main code of app.js is attached below: //Module dependency var express = require('express' );

      
var path = require('path'); var logger = require('morgan'); var http = require('http'); var favicon = require('serve-favicon'); var mongoose = require('mongoose'); var bodyParser = require('body-parser'); require('./models/schema'); var user = mongoose.model('User'); var cookieParser = require('cookie-parser'); var session = require('express-session'); var app = express(); //日志设置app.use(logger('dev')); //图标设置app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); //视图设置app.set('view engine', 'jade'); app.set('views', path.join(__dirname, 'views')); //静态文件设置app.use(express.static(path.join(__dirname, 'public'))); //表单数据解析app.use(bodyParser.json()); app.use(bodyParser.urlencoded( { extended: true } )); //路由设置var routes = require('./routes/index'); app.use('/', routes); //服务器设置var server = app.listen(8081, function () { var host = server.address().address var port = server.address().port console.log('server start on 127.0.0.1:8081'); } )
