预览特效
http://0752i.com/js/js/js_7.htm
1.首先请在在<body></body>之间输入下面的代码
<script language="JavaScript1.2">
var scrollerwidth=88
var scrollerheight=31
var scrollerbgcolor='black'
var pausebetweenimages=2000 //毫秒,logo轮换显示的时间间隔，2000=2秒
var slideimages=new Array()
//主要修改部分,可以适当增加
slideimages[0]='<a href="http://0752i.com/" target=_blank><img src="image/d01.gif" border="0"></a>'
slideimages[1]='<a href="http://0752i.com/" target=_blank><img src="image/d02.gif" border="0"></a>'
slideimages[2]='<a href="http://0752i.com/" target=_blank><img src="image/d03.gif" border="0"></a>'
slideimages[3]='<a href="http://0752i.com/" target=_blank><img src="image/d04.gif" border="0"></a>'
slideimages[4]='<a href="http://0752i.com/" target=_blank><img src="image/d05.gif" border="0"></a>'
//一下部分不用修改
if (slideimages.length>1)
i=2
else
i=0
function move1(whichlayer){
tlayer=eval(whichlayer)
if (tlayer.top>0&&tlayer.top<=5){
tlayer.top=0
setTimeout("move1(tlayer)",pausebetweenimages)
setTimeout("move2(document.main.document.second)",pausebetweenimages)
return
}
if (tlayer.top>=tlayer.document.height*-1){
tlayer.top-=5
setTimeout("move1(tlayer)",100)
}
else{
tlayer.top=scrollerheight
tlayer.document.write(slideimages[i])
tlayer.document.close()
if (i==slideimages.length-1)
i=0
else
i++
}
}
function move2(whichlayer){
tlayer2=eval(whichlayer)
if (tlayer2.top>0&&tlayer2.top<=5){
tlayer2.top=0
setTimeout("move2(tlayer2)",pausebetweenimages)
setTimeout("move1(document.main.document.first)",pausebetweenimages)
return
}
if (tlayer2.top>=tlayer2.document.height*-1){
tlayer2.top-=5
setTimeout("move2(tlayer2)",100)
}
else{
tlayer2.top=scrollerheight
tlayer2.document.write(slideimages[i])
tlayer2.document.close()
if (i==slideimages.length-1)
i=0
else
i++
}
}
function move3(whichdiv){
tdiv=eval(whichdiv)
if (tdiv.style.pixelTop>0&&tdiv.style.pixelTop<=5){
tdiv.style.pixelTop=0
setTimeout("move3(tdiv)",pausebetweenimages)
setTimeout("move4(second2)",pausebetweenimages)
return
}
if (tdiv.style.pixelTop>=tdiv.offsetHeight*-1){
tdiv.style.pixelTop-=5
setTimeout("move3(tdiv)",100)
}
else{
tdiv.style.pixelTop=scrollerheight
tdiv.innerHTML=slideimages[i]
if (i==slideimages.length-1)
i=0
else
i++
}
}
function move4(whichdiv){
tdiv2=eval(whichdiv)
if (tdiv2.style.pixelTop>0&&tdiv2.style.pixelTop<=5){
tdiv2.style.pixelTop=0
setTimeout("move4(tdiv2)",pausebetweenimages)
setTimeout("move3(first2)",pausebetweenimages)
return
}
if (tdiv2.style.pixelTop>=tdiv2.offsetHeight*-1){
tdiv2.style.pixelTop-=5
setTimeout("move4(second2)",100)
}
else{
tdiv2.style.pixelTop=scrollerheight
tdiv2.innerHTML=slideimages[i]
if (i==slideimages.length-1)
i=0
else
i++
}
}
function startscroll(){
if (document.all){
move3(first2)
second2.style.top=scrollerheight
}
else if (document.layers){
document.main.visibility='show'
move1(document.main.document.first)
document.main.document.second.top=scrollerheight+5
document.main.document.second.visibility='show'
}
}
window.onload=startscroll
</script>
2.然后在你需要显示特效的地方放置下面的这个代码
<script language="JavaScript1.2">
if (document.all){
document.writeln('<span id="main2" style="position:relative;width:'+scrollerwidth+';height:'+scrollerheight+';overflow:hiden;background-color:'+scrollerbgcolor+'">')
document.writeln('<div style="position:absolute;width:'+scrollerwidth+';height:'+scrollerheight+';clip:rect(0 '+scrollerwidth+' '+scrollerheight+' 0);left:0;top:0">')
document.writeln('<div id="first2" style="position:absolute;width:'+scrollerwidth+';left:0;top:1;">')
document.write(slideimages[0])
document.writeln('</div>')
document.writeln('<div id="second2" style="position:absolute;width:'+scrollerwidth+';left:0;top:0">')
document.write(slideimages[1])
document.writeln('</div>')
document.writeln('</div>')
document.writeln('</span>')
}
</script>
3.请按下面说明修改代码!
--这里只有5个logo轮换显示,如果你要增加或者删除都是修改第一步中的代码
--准备5个要轮换显示的logo, 取名为d01.gif --> d05.gif,或者修改第一步代码中的文件名
--修改第一步代码中的连接,以适合每个logo所对应的地方
