我正在使用 socket.io 和节点构建聊天Web应用程序。我使用innerHTML在div中添加用户的聊天,但问题是,当一条新消息被添加到聊天容器(div块)时,聊天容器中存在的先前媒体会在每次添加新聊天时重新加载。我想避免这种情况。任何人都可以帮我找到解决方案吗?我很想听听你的想法。这是我正在使用的抽象代码HTML<input type = "text" id = "message" placeholder="Type something..." /><i onclick = "sendMessage()" style="color:green;" title="Send" id="sendbtn"></i>我没有在表单元素中使用输入客户:function sendMessage(){ var msg = document.getElementById("message").value; if (msg) { postFile({message: msg,id:id, user: user, color: color,roomid:nativeRoom}); socket.emit("msg", { message: msg,id:id, user: user, color: color,roomid:nativeRoom}); }}socket.on("newmsg",function(data){ postFile(data); //Actually postFile is here because it can include video,audio as well});function postFile(data){//here i want to prevent message-container div from reloading its previous media(i have ignored most of the css code to make it precise) document.getElementById('message-container').innerHTML += '<div class="messages '+data.user+'chatpiece" id="'+data.id+'"><div><div><b>'+data.user+'</b><img src="'+userprofileimagelink+'"/></div><span>' +{time_when_message_posted} +'</span></div><hr><span style="max-width:100%;word-wrap:break-word;font-size:1.1em;" class="messagemain">' +data.message+"</span></div>"; }服务器端:socket.on('msg',function(data){ socket.broadcast.to(data.roomid).emit('newmsg',data);});我想避免在添加新消息时重新加载聊天容器中存在的视频和音频媒体。我怎样才能做到这一点?
