大家探讨一下对联广告的滑动代码
以下这段代码在：ads/CreateJs/Couplet.js里
写的是对联广告的滑动功能，大家探讨一下在上滑时如何才能改为滑到指定的位置就不再向上滑动了：
if (navigator.appName == "Netscape")
document.ns = navigator.appName == "Netscape"
window.screen.width>800 ? imgheight=160:imgheight=150
window.screen.width>800 ? imgleft=10:imgleft=30
window.screen.width>800 ? imgRight=10:imgRight=30
function Adsload_Couplet()
{
if (navigator.appName == "Netscape")
{
document.AdsLayerLeft.pageY=pageYOffset+10;
document.AdsLayerLeft.pageX=imgleft;
document.AdsLayerRight.pageY=pageYOffset+10;
document.AdsLayerRight.pageX=imgRight;Adsmove_Couplet();
}
else
{
AdsLayerLeft.style.top=document.body.scrollTop+10;
AdsLayerLeft.style.left=imgleft;
AdsLayerRight.style.top=document.body.scrollTop+10;
AdsLayerRight.style.right=imgRight;
Adsmove_Couplet();
}
}
function Adsmove_Couplet()
{
if(document.ns)
{
document.AdsLayerLeft.top=pageYOffset+10
document.AdsLayerLeft.left=imgleft;
document.AdsLayerRight.top=pageYOffset+10
document.AdsLayerRight.right=imgRight;
setTimeout("Adsmove_Couplet();",80)
}
else
{
AdsLayerLeft.style.top=document.body.scrollTop+10;
AdsLayerLeft.style.left=imgleft;
AdsLayerRight.style.top=document.body.scrollTop+10;
AdsLayerRight.style.right=imgRight;
setTimeout("Adsmove_Couplet();",80)
}
}
Adsload_Couplet();
