我们可以通过以下步骤使用 PugJs、NodeJS、MongoDB、Express 创建反馈表单。反馈表接收用户的输入并将数据发送到服务器进行处理,并将其相应地存储到数据库中。
步骤1:在任何目录中创建一个名为feedback_form 的文件夹。你可以取任何名字。
第 2 步:使用以下命令初始化 NodeJS 项目。
npm init –y
第 3 步:从终端/cmd 使用以下命令安装所需的模块。
// Express middleware
npm install express --save
// Database setup
npm install mongoose --save
// pugjs for client site rendering
npm install pug --save
// OR you can install all command
// using single command
npm install express pug mongoose
第 4 步:目录结构如下所示。
- node_modules:它包含我们所有已安装的节点模块。
- 静态:它包含服务器的静态文件。
- 视图:它包含要呈现到客户端站点的 PugJS 文件。
- app.js:它包含运行此应用程序的服务器代码。
第 5 步:安装模块后,记下以下代码以创建反馈表。
文件名:app.js
Javascript
// Require express to make easy
// routing on server side.
const express = require("express");
// Creating express object
const app = express();
// Require path module
const path = require('path');
// Require pug template engine
const pug = require("pug");
// Require mongoose to use mongoDb
// in a easier way
const mongoose = require("mongoose");
// Define a port number
const port = 3000;
// Make a static route to use your
// static files in client side
app.use('/static', express.static('static'));
// Middleware for parsing
app.use(express.urlencoded());
// Define and use pug engine so also
// declare path on rendering
app.set('view engine', 'pug');
app.set('views', path.join(__dirname, 'views'));
// Database Connection
mongoose.connect(
"mongodb://localhost:27017/feedback",
{ useUnifiedTopology: true }
);
// Create schema
const feedSchecma = mongoose.Schema({
name: String,
email: String,
feed: String
});
// Making a modal on our already
// defined schema
const feedModal = mongoose
.model('feeds', feedSchecma);
// Handling get request
app.get('/', function (req, res) {
// Rendering your form
res.render('feedback_form');
});
// Handling data after submission of form
app.post("/feedback_form", function (req, res) {
const feedData = new feedModal({
name: req.body.name,
email: req.body.email,
feed: req.body.feedback
});
feedData.save()
.then(data => {
res.render('feedback_form',
{ msg: "Your feedback successfully saved." });
})
.catch(err => {
res.render('feedback_form',
{ msg: "Check Details." });
});
})
// Server setup
app.listen(port, () => {
console.log("server is runing");
});

padding: 4px 10px;

border: 1px solid gray;

cursor: pointer;
}
步骤 6:使用以下命令运行app.js 文件:
node app.js
设计预览:
填写表格:
提交后:
MongoDB 命令:使用这些命令查看您的数据库记录:
mongo // Start mongo shell
show dbs // See database cluster
use feedback // Use table name
show collections // See collections in cluster
db.feeds.find() // See records with table name
输出:
