JS仿marquee無縫滾動實用篇+JS随機生成字元
主要應用于預約挂号滾動等！ 
JS仿marquee無縫滾動實用篇+JS随機生成字元串
1. 第一種marquee直接應用
别忘了寫overflow:hidden屬性，這個很重要！還有如果頁面不滾動，父div屬性要加上position:relative
demo寬高可根據div大小随意調整！
<span style="font-size:14px;"> <div id=demo style="overflow:hidden; width:128px; height:300px;">
<div id=demo1>
<li> <span>女士</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士1</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士2</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士3</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士4</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士5</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士6</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士7</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
<li> <span>女士8</span> <span>無痛人流</span> <span>三分鐘前</span> </li><br/>
</div>
<div id="demo2">
</div>
</div>
<script language="javascript">
var speed = 30;
document.getElementById('demo2').innerHTML = document.getElementById('demo1').innerHTML;
function Marquee(){
//alert(document.getElementById('demo2').offsetTop);
//alert(document.getElementById('demo1').offsetHeight);
if(document.getElementById('demo2').offsetTop-document.getElementById('demo').scrollTop<=0){
document.getElementById('demo').scrollTop-=document.getElementById('demo1').offsetHeight;
}else{
document.getElementById('demo').scrollTop++;
}
}
var MyMar=setInterval('Marquee()',speed);
document.getElementById('demo').οnmοuseοver=function(){clearInterval(MyMar)};
document.getElementById('demo').οnmοuseοut=function(){MyMar=setInterval(Marquee,speed)};
</script></span>
2.scrolltext.js 滾動JS
附上效果圖，滾動中并随機生成時間，随機病種 和姓名
function ScrollText(content,btnPrevious,btnNext,autoStart)
{
this.Delay = 10;
this.LineHeight = 20;
this.Amount = 1;//娉ㄦ剰:LineHeight涓€瀹氳鑳芥暣闄mount.
this.Direction = "up";
this.Timeout = 1500;
this.ScrollContent = this.$(content);
this.ScrollContent.innerHTML += this.ScrollContent.innerHTML;
//this.ScrollContent.scrollTop = 0;
if(btnNext)
{
this.NextButton = this.$(btnNext);
this.NextButton.onclick = this.GetFunction(this,"Next");
this.NextButton.onmouseover = this.GetFunction(this,"Stop");

}
ScrollText.prototype.AutoScroll = function()
{

{
if(parseInt(this.ScrollContent.scrollTop) >= parseInt(this.ScrollContent.scrollHeight) / 2)
{

}
this.ScrollContent.scrollTop += this.Amount;
}
else
{

{

}
this.ScrollContent.scrollTop -= this.Amount;
}

}
else

}
}
ScrollText.prototype.Scroll = function(direction)
{
if(direction=="up")
{
if(this.ScrollContent.scrollTop == 0)
{
this.ScrollContent.scrollTop = parseInt(this.ScrollContent.scrollHeight) / 2;
}
this.ScrollContent.scrollTop -= this.Amount;
}
else
{

}
if(parseInt(this.ScrollContent.scrollTop) >= parseInt(this.ScrollContent.scrollHeight) / 2)
{
this.ScrollContent.scrollTop = 0;
}
if(parseInt(this.ScrollContent.scrollTop) % this.LineHeight != 0)
{
this.ScrollTimer = setTimeout(this.GetFunction(this,"Scroll",direction), this.Delay);
}
}
ScrollText.prototype.GetFunction = function(variable,method,param)
{
return function()
{
variable[method](param);
}
}
這個不願意讀的就直接複制好了，很好用！
