做一个聊天室 用两个div.innerHTML 结果只有一个可用

Question

但是只有一个DIV可以显示出内容。。

Answer 1

ChatRoom.GetNewMsgString().value; 
      
    
ChatRoom.GetSiLiao().value; 
是不是上面的代码不能同时兼容，只能执行一个从而导致另一个出错？？

Answer 2

这个是调用了AJAX.DLL文件 实现无刷新的 后台的方法没有问题~而且如果注释掉其中一个DIV另一个就可以正常显示聊天内容了
function send()
  {
    if(ChatRoom.ISnotSend().value ==1)
    {
       var txtContent = document.all("content").value; //文本框输入内容
       if (txtContent == "")return;
       var user_to = document.all("userlist").value;  //聊天对象
       var textcolor = document.all("textcolor").value;  //颜色
       var isPublic = !(document.all("isSecret").checked);  //是否密谈 
       
       //调用服务器端方法发送消息
       ChatRoom.SendMsg(txtContent, user_to, textcolor, isPublic);
       
       //更新聊天内容显示
//       var txt = ChatRoom.GetNewMsgString().value;
//       
//       var aaa = document.all("chatcontent");
//       
//       aaa.innerHTML = txt + aaa.innerHTML;
       
   }
   else
   {
    alert("你已经被禁言");
   }
   ssend();
   //清空输入框
   document.all("content").value = "";
  }
  function ssend()
  {
       var stxt = ChatRoom.GetSiLiao().value;
       
       var bbb = document.all("chatsiliao");
       
       bbb.innerHTML = stxt + bbb.innerHTML;
  }

下面是后台的方法
/// <summary>
        /// 获取新消息的html字符串
        /// </summary>
        /// <returns>客户端输出的html字符串</returns>
        [Ajax.AjaxMethod(Ajax.HttpSessionStateRequirement.Read)]

        {
            string strMsgHTML = "";

            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "GetNewMsg";
            cmd.Parameters.Add("@uname", UName);            conn.Open();
            using (SqlDataReader dr = cmd.ExecuteReader())

                while (dr.Read())
                {

                    {
                        strMsgHTML += string.Format(

                    }
                }
            }
            conn.Close();            SetMsgPos();            return strMsgHTML;

Answer 4

应该连续AJAX回调了2次的问题
更新聊天内容显示 可以用定时刷新

Answer 5

已经用了定时刷新~但是这里也只是一个DIV显示 

Answer 6

组件不鸟解，如果是手写还可以帮你看下js而且看你的js代码逻辑不太对啊，你只是发表留言时才更新聊天记录
function send() 
  { 
    if(ChatRoom.ISnotSend().value ==1) 
    { 
      var txtContent = document.all("content").value; //文本框输入内容 
      if (txtContent == "")return; 
      var user_to = document.all("userlist").value;  //聊天对象 
      var textcolor = document.all("textcolor").value;  //颜色 
      var isPublic = !(document.all("isSecret").checked);  //是否密谈 
      
      //调用服务器端方法发送消息 
      ChatRoom.SendMsg(txtContent, user_to, textcolor, isPublic); 
      
      //更新聊天内容显示 
//      var txt = ChatRoom.GetNewMsgString().value; 
//      
//      var aaa = document.all("chatcontent"); 
//      
//      aaa.innerHTML = txt + aaa.innerHTML; 
      
  } 
  else 
  { 
    alert("你已经被禁言"); 
  } 
  ssend(); 
  //清空输入框 
  document.all("content").value = ""; 
  } 
 function ssend() 
  { 
      var stxt = ChatRoom.GetSiLiao().value; 
      
      var bbb = document.all("chatsiliao"); 
      
      bbb.innerHTML = stxt + bbb.innerHTML; 
//==============================将聊天记录更新放入ssend()函数里面看看
      var txt = ChatRoom.GetNewMsgString().value; 
      
      var aaa = document.all("chatcontent"); 
      
      aaa.innerHTML = txt + aaa.innerHTML; 
  }
