好多年没碰过前端jquery了，用一两天时间重温一下，刚好写个小工具
1. 后台
var fs = require(‘fs‘) var path = require(‘path‘) var basePath = ‘docs‘ let markdown = require(‘markdown-it‘) var md = new markdown({ html: true, langPrefix: ‘code-‘, }) function mkCate(cate) { fs.mkdir(path.join(basePath, cate)) } function getDirsInDocsFolder() { var paths = fs.readdirSync(basePath) return paths } function getMdsInFolder(folderName) { let paths = fs.readdirSync(path.join(basePath, folderName)) return paths } function writeMdFile(fileName, folderPath, content) { fs.writeFile(path.join(basePath, folderPath, fileName + ".md"), content, function (err) { console.error(err) }) } function readMdFileToHtml(fileName, folderPath) { var content = fs.readFileSync(path.join(basePath, folderPath, fileName), ‘utf-8‘) var html = md.render(content) return html } function main() { console.log(‘Starting web server‘) var express = require(‘express‘) var app = express() app.use(express.static(‘.‘)) const bodyParser = require(‘body-parser‘); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.get(‘/‘, function (req, res, next) { }) app.get(‘/cates‘, function (req, res, next) { var list = getDirsInDocsFolder() res.send(list) }) app.post(‘/cate‘, function (req, res, next) { const { cate } = req.body mkCate(cate) }) app.get(‘/mds‘, function (req, res, next) { const { cate } = req.query if (!cate) res.send([]) var mds = getMdsInFolder(cate) res.send(mds) }) app.get(‘/md‘, function (req, res, next) { const { cate, name } = req.query var html = readMdFileToHtml(`${name}.md`, cate) res.send(html) }) app.post(‘/md‘, function (req, res, next) { const { cate, name, content } = req.body writeMdFile(cate, name, content) res.send(content) }) var server = app.listen(8081, function () { const { host, port } = server.address() console.log(‘Listening on http://%s:%s‘, host, port) }) } main();

3. scss样式
$common-height: 150px; @mixin with100minus($px) { width: calc(100% - #{$px}); } @mixin height100($px) { height: calc(100% - #{$px}); } * { box-sizing: border-box; } h1 { color: red; } ul li { list-style-type: none; } nav { width: 100%; display: flex; flex-direction: row; justify-content: flex-start; text-align: right; a { margin-left: 15px; display: block; } a:first-child { margin-left: 0; } } div { float: left; } .menu { width: 200px; height: $common-height; } .main { @include with100minus(200px); @include height100(200px); background-color: orange; } iframe { width: 100%; min-height: 500px; } footer { position: fixed; bottom: 0px; text-align: center; width: 100%; } button { border-radius: 5px; }
