功能:文字无缝滚动 (向左+向上)
向左滚动:
Jquery代码:
<script language="javascript" type="text/javascript">
<!--
function scroll(obj) {
var tmp = (obj.scrollLeft)++;
//当滚动条到达右边顶端时
if (obj.scrollLeft==tmp) obj.innerHTML += obj.innerHTML;
//当滚动条滚动了初始内容的宽度时滚动条回到最左端
if (obj.scrollLeft>=obj.firstChild.offsetWidth) obj.scrollLeft=0;
}
var t = setInterval("scroll(document.getElementById('scrollobj'))",40);
$("#scrollobj").mouseover(function(){
clearInterval(t);
});//鼠标经常时,停止滚动
$("#scrollobj").mouseout(function(){
setInterval(t = setInterval("scroll(document.getElementById('scrollobj'))",40))
});//鼠标离开时,重新执行函数
//-->
</script>
HTML代码:
<DIV id="scrollobj" style="white-space:nowrap;overflow:hidden;width:500px;"><span>这里是要滚动的内容</span></DIV>
向上滚动:
Jquery代码:
<script language="javascript">
var speed=30;
var demo2=document.getElementById("demo2");
var demo1=document.getElementById("demo1");
var demo=document.getElementById("demo");
demo2.innerHTML=demo1.innerHTML;
function Marquee(){
if(demo2.offsetTop-demo.scrollTop<=0){
demo.scrollTop-=demo1.offsetHeight;
}
else{
demo.scrollTop++;
}
}
var MyMar=setInterval(Marquee,speed);
demo. {clearInterval(MyMar)};
demo. {MyMar=setInterval(Marquee,speed)};
</script>
HTML代码:
<div id="demo" style="overflow:hidden;height:168px;width:300px;">
<div id="demo1">
<!--此处放要显示的内容-->
<p>a</p><p>a</p><p>a</p><p>a</p><p>a</p><p>a</p><p>a</p><p>a</p>
</div>
<div id="demo2"></div>
</div>
