本文实例讲述了JS实现消息来时让网页标题闪动效果的方法。分享给大家供大家参考，具体如下：
<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()
{

{
clearInterval(g_blinkid);
g_blinkid = 0;
document.title = g_blinktitle;
}
}
