【图】垂直滚动信息板

　　第一步：请将下列原代码放入html文件的head和/head之间:

script
!--
lstart=160
loop=true
speed=350
pr_step=5
functionmakeObj(obj,nest){
nest=(!nest)？'':'document.'+nest+'.'
this.css=(document.layers)？
eval(nest+'document.'+obj):eval(obj+'.style')
this.scrollHeight=document.layers？this.css.document.height:eval(obj+'.
offsetHeight')
this.up=goUp
this.obj=obj+"Object"
eval(this.obj+"=this")
returnthis
}
functiongoUp(speed){
if(parseInt(this.css.top)-this.scrollHeight){
this.css.top=parseInt(this.css.top)-pr_step
setTimeout(this.obj+".up("+speed+")",speed)
}elseif(loop){
this.css.top=lstart
eval(this.obj+".up("+speed+")")
}
}
functionslideInit(){
oSlide=makeObj('divNews','divCont')
oSlide.css.top=lstart
oSlide.up(speed)
}
onload=slideInit
//--
/script

　　注：其中lstart设置起始位置，loop设置是否循环，speed是滚动速度，pr_step设置间距。

　　第二步：请将下列代码放入html文件的任何地方，建议放在最后，就是/html之后:

divid="divCont" style="position:absolute;width:300;height:100;top:120;left:280; clip:rect(0,250,150,0)"
divid="divNews"style="position:absolute;top:0;left:0"
