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() { 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" /> </div> </form> </body> </html>
