我正在按照本教程创建表单：
https://bootstrapious.com/p/how-to-build-a-working-bootstrap-contact-form
在联系表单HTML的底部，我添加了脚本：
<script src='https://code.jquery.com/jquery-1.12.0.min.js'></script>
<script src='https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js'> </script>
<script src='js/validator.js'></script>
<script src='js/contact.js'></script>
验证器文件来自我下载的Bootstrap。我知道它有效，因为它填写了我的表格。
当我提交表格时，没有任何反应。我在控制台中收到以下错误：
POST http://www.example.com/php/contact.php 404 (Not Found)
我把php文件放在php文件夹中，这样部分已经改变，但其他一切都是一样的。我已经尝试将php文件放在与联系页面相同的文件夹中并获得类似的消息：
POST http://www.example.com/contact.php 404 (Not Found)
我想知道是不是因为我正在使用node和express。我想在以下index.js文件中做一些事情？
这是我的index.js：
const express = require('express');
const app = express();
const port = process.env.PORT || 3000;
app.use(express.static('public'));
app.set('view engine', 'ejs');
app.get('/', function (request, response) {
response.render('index');
});
app.get('/projects', function (request, response) {
response.render('projects');
});
app.get('/about', function (request, response) {
response.render('about');
});
app.get('/contact', function (request, response) {
response.render('contact');
});
app.listen(port, function () {
console.log('Listening on port ' + port);
});
以下是“联系”页面上的表单 - HTML：

答案 0 :(得分：0)
我对节点不够深入，并表示要完全知道你的JavaScript是否可靠。我只能给出的建议是尝试在该教程中显示的JS，并将文件放在同一个位置。基本上重新创造一切。
之后，尝试将contact.php放在php文件夹中并修复操作。看看是否有效。
如果是这样，那么你就会知道这是你的JS。我知道Bootstrap依赖于JQuery，因此如果您已经将JQuery用于Bootstrap的其他功能，那么您可能需要考虑使用它们的脚本。如果没有，那么只需逐步进行大量的错误消息传递，直到找到问题所在。
抱歉，我无法提供更好的帮助。祝你好运！
