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" onclick="stopBlinkNewMsg();" /> </div> </form> </body> </html>

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
