本文实例讲述了javascript动态添加删除tabs标签的方法。分享给大家供大家参考。具体实现方法如下：
<html>
<HEAD>
<TITLE>网页对话</TITLE>
<LINK href="style.css" type=text/css rel=stylesheet>
<script>
function $(obj)
{
var o = typeof(obj)=="object" "ChatBoard__"+ChannelId;
var LabelId="Label__"+ChannelId;
/* 如果频道已存在 **/if($(ChatBoardId)){
return ;bai
};
/* 添加控件,先删除原来 '等待客户连接' 这列 **/
var cell0=$("LabelContainer").childNodes[0];
if(cell0.id=='Label_Default')$("LabelContainer").removeChild(cell0);
$("ChatBoardContainer").appendChild(buildChatBoard(ChatBoardId));
$("LabelContainer").appendChild(buildLabel(LabelId,LabelText));
/* 显示新打开的聊天窗口 **/toggChatBoard(ChannelId);
};

};
