本文实例讲述了JS实现把鼠标放到链接上出现滚动文字的方法。分享给大家供大家参考，具体如下：

<div id="tooltip2" style="position:absolute;visibility:hidden;clip:rect(0 150 50 0);width:150px;background-color:seashell">

<layer name="nstip" width=1000px bgColor="seashell"></layer>

</div>

<SCRIPT language="JavaScript">

<!--

if (!document.layers&&!document.all)

event="test"

function showtip2(current,e,text){

if (document.all&&document.readyState=="complete"){

document.all.tooltip2.innerHTML='<marquee style="border:1px solid black">'+text+'</marquee>'

document.all.tooltip2.style.pixelLeft=event.clientX+document.body.scrollLeft+10

document.all.tooltip2.style.pixelTop=event.clientY+document.body.scrollTop+10

document.all.tooltip2.style.visibility="visible"

}

else if (document.layers){

document.tooltip2.document.nstip.document.write('<b>'+text+'</b>')

document.tooltip2.document.nstip.document.close()

document.tooltip2.document.nstip.left=0

currentscroll=setInterval("scrolltip()",100)

document.tooltip2.left=e.pageX+10

document.tooltip2.top=e.pageY+10

document.tooltip2.visibility="show"

}

}

function hidetip2(){

if (document.all)

document.all.tooltip2.style.visibility="hidden"

else if (document.layers){

clearInterval(currentscroll)

document.tooltip2.visibility="hidden"

}

}

function scrolltip(){

if (document.tooltip2.document.nstip.left>=-document.tooltip2.document.nstip.document.width)

document.tooltip2.document.nstip.left-=5

else

document.tooltip2.document.nstip.left=150

}

//--> 

</SCRIPT>

<a href=# onMouseOver="showtip2(this,event,'看到了吧？')" onMouseOut="hidetip2()">把鼠标放上来试试</a>

希望本文所述对大家JavaScript程序设计有所帮助。
