<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
<script>
var g_blinkid = 0;
var g_blinkswitch = 0;
var g_blinktitle = document.title;
var g_onlineuser = "";
var g_sysmsg_sound = null;
var g_newmsg_sound = null;
var g_app_num = 0;
var g_appnum = 0;
var g_bappmore = false;
var g_inputtime = 0;
function blinkNewMsg()
{
document.title = g_blinkswitch % 2==0 ? "【 】 - " + g_blinktitle : "【新消息】 - " + g_blinktitle;
g_blinkswitch++;
}
g_blinkid = setInterval(blinkNewMsg, 1000);
function stopBlinkNewMsg()
{
if (g_blinkid)
{
clearInterval(g_blinkid);
g_blinkid = 0;
document.title = g_blinktitle;
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Button1" type="button" value="button" onclick="stopBlinkNewMsg();" />
</div>
</form>
</body>
</html>
