js文本在一行内幻灯显示效果

文字用"|"隔开，具体使用方法：

 程序代码
<div id="marqueeBox"><div>人的头脑太复杂,时间过得久,有时候连自己也被自己骗了,记下来才是最真实的......|最上等的控制是知道何时放手!</div></div>

<script type="text/javascript" src="TextSlide.js"></script>
<script type="text/Javascript">
var Mar = new TextSlide("marqueeBox",4000,17);
Mar.init();
</script>

函数解释：

 引用内容
TextSlide(Objid,Delay,hg,flag)

Objid:要幻灯显示的对象ID;

Delay:切换延迟时间;

hg:显示高度;

flag:可选,显示类型:滚动和淡出两种,默认是滚动;

TextSlide.js代码如下:
