JS让一个DIV变成个聊天窗口
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>无标题页</title>
<style type="text/css">
#Chat
{
width: 550px;
height: 200px;
padding: 6px;
overflow-y: scroll;
word-break: break-all;
background: #ccc;
}
</style>
<script language="javascript" type="text/javascript">
function $(c){return document.getElementById(c);}
function SendMsgss()
{
var MSg= $("msg").value;
var newFontElem = document.createElement("font");
newFontElem.innerHTML =MSg+"<br/>";
$("Chat").appendChild(newFontElem);
$("Chat").scrollTop= $("Chat").scrollHeight;//每次收到消息吧滚动条拉到最下面
// var MSg= $("msg").value; 这个更简单但是为了后台Ajax返回等。。。。
// var msgK=$("Chat").innerHTML+=MSg+"<br/>";
}
</script>
</head>
<body>
<form id="form1">
<div id="Chat">
</div>
<input type="text" id="msg" />
<input type="button" id="send" value="SendMsgss" onclick="SendMsgss()" />
</form>
</body>
</html>
