我在letschat 文件夹中有index.html、css 和js 文件。运行 node express 服务器后，它不会加载 css 和 js 文件。我正在提供 server.js 代码。请让我知道如何解决这个问题。
var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io').listen(server);
users = [];
connections = [];
app.use("/letschat",express.static(__dirname + '/letschat'));
app.listen(process.env.PORT || 3000);
console.log('Server running....');
app.get('/letschat', function(req, res){
res.sendFile(__dirname + '/index.html');
});

$(函数(){
var socket = io.connect();
和我的 jquery 文件
在此处输入代码
$(文档).ready(函数(){
$('.chat_head').click(function(){
$('.chat_body').slideToggle('slow');
});
$('.msg_head').click(function(){
$('.msg_box').slideToggle('slow');
});
$(".close").click(函数(){
$('.msg_box').hide();
});
$(".user").click(function(){
$('.msg_wrap').show();
$('.msg_box').show();
});
应用程序仍处于初始开发阶段。我正在尝试使用聊天框在 node express 上托管 3 个文件。但 jquery 无法运行。请让我知道要执行的程序。
