首先,我们在样式表里加入“.opacity {FILTER: alpha(opacity=100)”,看下面!
以下是引用片段:
<style type="text/css">
<!--
.opacity {FILTER: alpha(opacity=100)}
-->
</style>
然后在html代码中加入:
<script>
function movstar(a,time){
movx=setInterval("mov("+a+")",time)
}
function movover(){
clearInterval(movx)
}
function mov(a){
scrollx=new_date.document.body.scrollLeft
scrolly=new_date.document.body.scrollTop
scrolly=scrolly+a
new_date.window.scroll(scrollx,scrolly)
}
function o_down(theobject){
object=theobject
while(object.filters.alpha.opacity>60){
object.filters.alpha.opacity+=-10}
}
function o_up(theobject){
object=theobject
while(object.filters.alpha.opacity<100){
object.filters.alpha.opacity+=10}
}
function wback(){
if(new_date.history.length==0){window.history.back()}
else{new_date.history.back()}
}
</script>
然后在向上箭头图片的代码中加入“class="opacity" onMouseDown=movover();movstar(-3,2) onMouseOut=movover();o_up(this) onMouseOver=movstar(-1,20);o_down(this) onMouseUp=movover();movstar(-1,20) alt="点住不放可以快速向上滚动"”。
