I'm doing the nodeJS tuto on openclassroom.
I use the template engine ejs. I try to run a simple JS script but I can't.
Here is my app structure:
App_toDoList/
│
├──app.js
├──package-lock.json
├──package.json
│
├── js/
├── node_modules/
└── views/
├── modify.ejs
└── todo.ejs
I run my server with app.js:
var express = require('express');
var session = require('cookie-session'); // Charge le middleware de sessions
var bodyParser = require('body-parser'); // Charge le middleware de gestion des paramètres
var urlencodedParser = bodyParser.urlencoded({ extended: false });
var app = express();
/* On utilise les sessions */
app.use(session({secret: 'todotopsecret'}))
/* S'il n'y a pas de todolist dans la session,
on en crée une vide sous forme d'array avant la suite */
.use(function(req, res, next){
if (typeof(req.session.todolist) == 'undefined') {
req.session.todolist = [];
}
next();
})
/* On affiche la todolist et le formulaire */
.get('/todo', function(req, res) {
res.render('todo.ejs', {todolist: req.session.todolist});
})
/* On ajoute un élément à la todolist */
.post('/todo/add/', urlencodedParser, function(req, res) {
if (req.body.newtodo != '') {
req.session.todolist.push(req.body.newtodo);
}
res.redirect('/todo');
})
/* Supprime un élément de la todolist */
.get('/todo/delete/:id(\\d+)', function(req, res) {
if (req.params.id != '') {
req.session.todolist.splice(req.params.id, 1);
}
res.redirect('/todo');
})
.get('/todo/modify/:id(\\d+)',function(req,res){
if (req.params.id != '') {
res.render('modify.ejs', {index: req.params.id, toModify: req.session.todolist[req.params.id]})
}
})
.post('/todo/modified/:id(\\d+)', urlencodedParser, function(req, res) {
if (req.body.modifytodo != '') {
req.session.todolist[req.params.id]=req.body.modifytodo;
}
res.redirect('/todo');
})
/* On redirige vers la todolist si la page demandée n'est pas trouvée */
.use(function(req, res, next){
res.redirect('/todo');
})
.listen(8080);
You can see that I call the render todo.ejs :
<!DOCTYPE html>
<html>
<head>
<title>Ma todolist</title>
<style>
a {
text-decoration: none;
color: black;
}
</style>
<script src="/js/myJS.js"></script>
</head>
<body>
<h1>Ma todolist</h1>
<ul>
<% todolist.forEach(function(todo, index) { %>
<li>
<a href="/todo/delete/<%= index %>">✘</a>
<%= todo %>
<a href="/todo/modify/<%= index %>">🛠️</a>
</li>
<% }); %>
</ul>
<form action="/todo/add/" method="post">
<p>
<label for="newtodo">Que dois-je faire ?</label>
<input type="text" name="newtodo" id="newtodo" autofocus />
<input type="submit" />
</p>
</form>
<input type="text" name="date" id="date">
</body>
</html>
My problem is that myJS.js script doesn't run. There is just an alert('hello') in it and no alert comes on my browser (Firefox)
The thing is if I save todo.ejs in todo.html (I erase ejs part), the alert appear.
I fear the problem comes from how my node server handles directory. I found this but it doesn't help me that much.
If you have any idea or questions feel free to tell me. I am a beginner in JS, node etc so the solution can be a child's play.
Thank you
