A. 求网络聊天室源码,用JSP或Servlet都行
用ajax和jsp写的,可以实现无刷新页面显示聊天记录js/js.js文件varnbsp;obj;varnbsp;getId=document.getElementById;functionnbsp;objXMLHttp(){nbsp;nbsp;nbsp;nbsp;varnbsp;XmlHttpObjnbsp;=nbsp;false;nbsp;nbsp;nbsp;nbsp;if(window.ActiveXObject)nbsp;nbsp;nbsp;nbsp;{nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;XmlHttpObjnbsp;=nbsp;newnbsp;ActiveXObject(“MSXML2.XMLHTTP.3.0“);nbsp;nbsp;nbsp;nbsp;}nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;elsenbsp;ifnbsp;(window.XMLHttpRequest)nbsp;nbsp;nbsp;nbsp;{nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;XmlHttpObjnbsp;=nbsp;newnbsp;XMLHttpRequest();nbsp;nbsp;nbsp;nbsp;}nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;returnnbsp;XmlHttpObj;}functionnbsp;sendMsg(auto){nbsp;obj=objXMLHttp();nbsp;if(!auto)//nbsp;{nbsp;nbsp;varnbsp;myContentnbsp;=nbsp;getId(“myText“).value;nbsp;nbsp;if(myContentnbsp;!=nbsp;““)nbsp;nbsp;{nbsp;nbsp;nbsp;if(obj)nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;{nbsp;nbsp;nbsp;nbsp;obj.onreadystatechangenbsp;=nbsp;addChat;nbsp;nbsp;nbsp;nbsp;obj.open(“POST“,“do.jsp“,nbsp;true);nbsp;nbsp;nbsp;nbsp;obj.setRequestHeader(“Content-Type“,“application/x-www-form-urlencoded;“);nbsp;nbsp;nbsp;nbsp;nbsp;obj.send(“myContent=“nbsp;+nbsp;myContent);nbsp;nbsp;nbsp;nbsp;getId(“myText“).value=““;nbsp;nbsp;nbsp;nbsp;getId(“myText“).focus();nbsp;nbsp;nbsp;nbsp;Scroll();nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;}nbsp;nbsp;}nbsp;nbsp;elsenbsp;nbsp;{nbsp;nbsp;nbsp;alert(“nbsp;(*^__^*)nbsp;你不告诉我们,我们怎么知道你们保持沉默呢“);nbsp;nbsp;nbsp;getId(“myText“).value=“保持沉默“;nbsp;nbsp;nbsp;getId(“myText“).focus();nbsp;nbsp;}nbsp;}nbsp;else//nbsp;{nbsp;nbsp;if(obj)nbsp;nbsp;{nbsp;nbsp;nbsp;obj.onreadystatechangenbsp;=nbsp;addChat;nbsp;nbsp;nbsp;obj.open(“POST“,“do.jsp“,nbsp;true);nbsp;nbsp;nbsp;obj.setRequestHeader(“Content-Type“,“application/x-www-form-urlencoded;“);nbsp;nbsp;nbsp;nbsp;obj.send(null);nbsp;nbsp;nbsp;Scroll();nbsp;nbsp;}nbsp;}}functionnbsp;addChat()//添加聊天记录{nbsp;varnbsp;docnbsp;=nbsp;““;nbsp;if(obj.readyStatenbsp;==nbsp;4nbsp;amp;amp;nbsp;obj.statusnbsp;==nbsp;200)nbsp;{nbsp;nbsp;doc=obj.responseText;nbsp;nbsp;if(docnbsp;!=nbsp;““)nbsp;nbsp;{nbsp;nbsp;nbsp;getId(“says“).value=doc;nbsp;nbsp;}nbsp;}}functionnbsp;getChatContent(){nbsp;tnbsp;=nbsp;setInterval(‘sendMsg(true)‘,800);}functionnbsp;quickSend(){nbsp;nbsp;if(getId(“sendType“).value==“ctrlEnter“)nbsp;{nbsp;nbsp;if(window.event.ctrlKeyamp;amp;window.event.keyCode==13)nbsp;nbsp;{nbsp;nbsp;nbsp;sendMsg(false);nbsp;nbsp;}nbsp;}nbsp;elsenbsp;if(getId(“sendType“).value==“enterKey“)nbsp;{nbsp;nbsp;if(window.event.keyCode==13)nbsp;nbsp;{nbsp;nbsp;nbsp;sendMsg(false);nbsp;nbsp;}nbsp;}}functionnbsp;loginConfirm(){nbsp;if(window.event.keyCode==13)nbsp;{nbsp;nbsp;checkUser();nbsp;}}functionnbsp;checkUser(){nbsp;if(getId(“userName“).value==nullnbsp;||nbsp;getId(“userName“).value=

C. 快速搭建一个匿名聊天室
大家好,我将介绍一个基于livekit 和 Next.js 构建的匿名聊天室 —— anonymous-chat-room。以下为搭建步骤:
请访问GitHub页面获取源码:GitHub地址
在线体验请移步到此网址:在线体验地址
本地部署步骤如下:
首先,将项目克隆或下载到本地计算机。
然后,转至项目所在目录。
执行命令安装项目依赖。
接着,在 cloud.livekit.io 创建一个新的 Project,并获取 apikey,通过项目设置界面获取。
根据提示,在env.example文件中修改环境变量,并将该文件重命名为 env.local。
最后,运行以下命令:
在浏览器中输入"http://localhost:3000",即可打开匿名聊天室。
此开源项目已收录至GitHub,欢迎点击star以示支持。
