如何设计让网页“双击自动滚屏”？

将以下代码添加到需要自动滚屏的页面上就可以了

<s cript Language="Javas cript">
var currentpos, timer;
function initialize(){
timer = setInterval("scrollwindow()", 1);
}
function sc(){
clearInterval(timer);
}
function scrollwindow(){
currentpos = document.body.scrollTop;
window.scroll(0, ++currentpos);
if(currentpos != document.body.scrollTop){
sc();
}
}
document.onmousedown = sc;
document.ondblclick = initialize;
</s cript>
