| 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"”。
