我在letschat文件夹中有index.html,css和js文件。运行节点快速服务器后,它没有加载css和js文件。我给的是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');
});

        </div>

    </div>
    <script>

$(函数(){

var socket = io.connect();

和我的jquery文件

在这里输入代码

(文档)$。就绪(函数(){

$( 'chat_head')。点击(函数(){

$( 'chat_body。 ')的slideToggle(' 慢');

});

$( 'msg_head')。点击(函数(){

$( 'msg_box。 ')的slideToggle(' 慢');

});

$( “关闭”)。单击(函数(){

$('.msg_box').hide();

});

$( “用户”)。单击(函数(){

$( 'msg_wrap。')示出了();

$( 'msg_box。')示出了();

});

App仍处于初始开发阶段。我试图通过聊天框在node express上托管3个文件。但是jquery没有运行。请让我知道要执行的程序。

1 个答案:

答案 0 :(得分:1)

执行此操作时:

app.use("/letschat", express.static(__dirname + '/letschat'));

您告诉Express,应在/letschat/styles.css中查找__dirname + '/letschat/styles.css'的请求。

因此,为了使其正常工作,HTML页面中的网址必须为/letschat/styles.css

如果您希望网页中的网址为/styles.css,请将您的服务器代码更改为:

app.use(express.static(__dirname + '/letschat'));
