JavaScript Cookies技术的一个应用举例，有记忆功能的“设为首页”，也就是说它只会在第一次打开网页的时候出现，不管用户是否点击了该功能，以后它都不会再出现，很好的提升了用户体验，不会使用户那么烦你的网页。

<html><head><title>Cookies“设为首页”</title><meta http-equiv="content-type" content="text/html;charset=gb2312"><script language="javascript">document.writeln("<style type=/"text/css/">");document.writeln("#oHomePage {behavior:url(#default#homepage)}");document.writeln("<//style>");document.writeln("<font ID=/"oHomePage/"><//font>");var h_imgheightdocument.ns = navigator.appName == "Netscape"window.screen.width>800 ? h_imgheight=200:h_imgheight=200function h_myload(){if (navigator.appName == "Netscape"){document.setdp.pageY=pageYOffset+window.innerHeight-h_imgheight;document.setdp.pageX=+window.innerWidth-400;h_mymove();}else{setdp.style.top=document.body.scrollTop+document.body.offsetHeight-h_imgheight;setdp.style.left=document.body.offsetWidth-400;h_mymove();}}function h_mymove(){if(document.ns){document.setdp.top=pageYOffset+window.innerHeight-h_imgheight;document.setdp.left=pageXOffset+window.innerWidth-550;setTimeout("h_mymove();",50)}else{setdp.style.top=document.body.scrollTop+document.body.offsetHeight-h_imgheight;setdp.style.left=document.body.scrollLeft+document.body.offsetWidth-550;setTimeout("h_mymove();",50)}}function h_MM_reloadPage(init) {//reloads the window if Nav4 resized  if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {    document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=h_MM_reloadPage; }}  else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();}h_MM_reloadPage(true)if (navigator.appName == "Netscape"){document.write("<layer id=/"setdp/" top=/"300/" width=/"80/" height=/"88/"><img src=http://www.aspku.com/"/jscss/demoimg/200908/sethome.gif/" width=/"157/" height=/"50/" border=/"0/" usemap=/"#Map2/"></layer>");h_myload()}else{document.write("<div id=/"setdp/" style=/"position: absolute;width:80;top:0;left:578;visibility:visible;z-index:1/"><img src=http://www.aspku.com/"/jscss/demoimg/200908/sethome.gif/" width=/"157/" height=/"50/" border=/"0/" usemap=/"#Map2/"></div>");h_myload()}if (h_getcookie()){		setdp.style.display="none";	}function setd(b){var default_href="http://www.vevb.com";if (b=="yes"){	oHomePage.setHomePage(default_href);	h_WriteCookie("yes");	setdp.style.display="none";	return false;}else{h_WriteCookie("no");setdp.style.display="none";return false;}}function h_WriteCookie(b){	if (b=="yes"){	var e = new Date ();	e.setTime (e.getTime() + (365*24*60*60*1000));	e = e.toGMTString()	}	else{	var e = new Date ();	e.setTime (e.getTime() + (24*60*60*1000));	e = e.toGMTString();	}	document.cookie="setd=yes;path=/;expires="+e+"domain=codefans.net"}function h_getcookie(){ck=document.cookie;	if (ck.indexOf("setd=yes")!=-1){	return true;	}	else 	{return false;}}document.writeln("<map name=/"Map2/">");document.writeln("");document.writeln("");document.writeln("<//map>");</script></head><body></body></html>
