　　js|广告|时钟

　　大家自己运行看看吧。

　　1、判断网页是否过期 getTime()

用于实现广告过期.

<head><h1>判断网页是否过期</h1><hr><script></script>

　　2、在线时钟实例 setTimeout()函数

setTimeout()函数
TimerID = setTimeout('showtime',1000)
通过setTimeout 来刷新时间间隔1000=1秒

<head><script></script></head><body ><Form name="CLOCK"><input name="ALARM" type="text" size="45" value="">如无效果请刷新</form></body>

　　3、status window自带函数状态栏提示

<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>无标题文档</title><script></script></head><body><a href="abc.htm" onmouseover='window.status="abc.htm";return true'>abc</a><br><a href="def.htm" onmouseover='window.status="def.htm";return true'>def</a></body></html>

　　4、setTimeout 函数，自动链向新网站

<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><script language="JavaScript"></script></head><body >我们的网站搬新家了!请单击下面的超链接进入我们的新网站<br><a href="http://homepage.yesky.com">网页陶吧</a><br> 2秒后自动进入新的网站，请耐心等待。</body></html>

　　5、广告字幕实例

设置0.3秒后再次调用MARQUEE()函数
TimerID = setTimeout("marquee()",300)
广告字幕触发事件
<body >

<head><script><!--var ShowString =" " +"Space,The final frontier... These are the" +"voyages of the Starship Enterprise, its" +"continuing mission: to explore strange" +"new worlds, to seek out new life and new" +"civilizatins, to boldly go where no man" +"has gone before.______________________________" +"宇宙,人类的最终边界....太空船企业号的旅程," +"是为了探索陌生新世界,找寻新生命与新文明,勇" +"驶向人类足迹从未的领域."//--------------------------------var ShowWidth = 50var ShowHead = 0var ShowTail = ShowWidthvar ShowLength= ShowString.length//--------------------------------function marquee(){var DisplayStringif (ShowHead<ShowTail) DisplayString = ShowString.substring(ShowHead,ShowTail) else DisplayString = ShowString.substring(ShowHead,ShowLength) +ShowString.substring( 0,ShowTail)//--------------------------------ShowHead = (ShowHead + 2) % ShowLengthShowTail = (ShowTail + 2) % ShowLength//--------------------------------document.RUNNING.SHOWPAD.value = DisplayString//--------------------------------TimerID = setTimeout("marquee()",300)}//-></script></head><body ><center><form name="RUNNING"><INPUT NAME="SHOWPAD" size=40 Type="text" value="">如无效果请刷新。</form></center></body>
