你谢我阿？难得哦~~我也有关闭窗口，这个是不会弹出提示直接关的： 
把如下代码加入<body>区域中 
<OBJECT id=closes type="application/x-oleobject" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11"> 
<param name="Command" value="Close"> 
</object> 
<script language="javascript">function shutwin(){closes.Click();return;}</script>

随机图片： 
把如下代码加入<body>区域中 
<script language="javascript"><!-- 
today=new Date(); 
jran=today.getTime(); 
function rnd() { 
ia=9301; 
ic=49297; 
im=233280; 
jran = (jran*ia+ic) % im; 
return jran/(im*1.0); 
}; 
function rand(number) { 
return Math.ceil(rnd()*number); 
}; 
document.write("<CENTER>"); 
for(i=1;i<=1;i++) { 
myNum=(rand(10)); //改成你要随机显示的图片数； 
if(myNum == 1) document.write("<img src='http://old.zzzyk.com/article/Article/photo/back.jpg'>"); 
if(myNum == 2) document.write("<img src='http://old.zzzyk.com/article/Article/photo/j2.gif'>"); //图片路径，可用http:// ;
if(myNum == 3) document.write("<img src='http://old.zzzyk.com/article/Article/photo/email.gif'>"); 
if(myNum == 4) document.write("<img src='http://old.zzzyk.com/article/Article/photo/arrow.gif'>"); 
if(myNum == 5) document.write("<img src='http://old.zzzyk.com/article/Article/photo/j2.gif'>"); 
if(myNum == 6) document.write("<img src='http://old.zzzyk.com/article/Article/photo/email.gif'>"); 
if(myNum == 7) document.write("<img src='http://old.zzzyk.com/article/Article/photo/arrow.gif'>"); 
if(myNum == 8) document.write("<img src='http://old.zzzyk.com/article/Article/photo/j2.gif'>"); 
if(myNum == 9) document.write("<img src='http://old.zzzyk.com/article/Article/photo/back.jpg'>"); 
if(myNum == 10) document.write("<img src='http://old.zzzyk.com/article/Article/photo/email.gif'>"); 
else { 
document.write(); 
} 
}; 
document.write("</CENTER>"); 
//--> 
</script> 
其实改一改随机什么都行，也不一定在body中
图片显隐效果 
脚本说明: 
把如下代码加入<body>区域中 
<script language=javascript> 
// Flash Image Extension for Dreamwever ,by Yichun Yuan(dezone@sina.com) 
nereidFadeObjects = new Object(); 
nereidFadeTimers = new Object(); 
function nereidFade(object, destOp, rate, delta){ 
if (!document.all) 
return 
if (object != "[object]"){ //do this so I can take a string too 
setTimeout("nereidFade("+object+","+destOp+","+rate+","+delta+")",0); 
return; 
} 
clearTimeout(nereidFadeTimers[object.sourceIndex]); 
diff = destOp-object.filters.alpha.opacity; 
direction = 1; 
if (object.filters.alpha.opacity > destOp){ 
direction = -1; 
} 
delta=Math.min(direction*diff,delta); 
object.filters.alpha.opacity+=direction*delta; 
if (object.filters.alpha.opacity != destOp){ 
nereidFadeObjects[object.sourceIndex]=object; 
nereidFadeTimers[object.sourceIndex]=setTimeout("nereidFade(nereidFadeObjects["+object.sourceIndex+"],"+destOp+","+rate+","+delta+")",rate); 
} 
} 
</script>
