<p class="p2" style="line-height:17pt"> 这个例子会让您看上去觉得眼花缭乱，在输入栏中输入不同的时间间隔会以不同的速度显示。<a href="sl/dttimecontrol.htm" target="_blank"><img src="img/link.gif" width="127" height="20" align="absmiddle" border="0" alt="链接"></a><br>
这里面主要用的是revealtrans滤镜属性，在每一个区域内都添加了revealtrans属性，再让它们调用onfilterchange函数。而输入时间间隔是靠javascript的onchange<br>
事件实现的，下面我们把有关CSS的代码列出如下：</p>
<p class="p2" style="line-height:17pt"> <body onload="init()"> <br>
<span style="position:absolute;top:140;left:20;width:400;<br>
text-align:center; font-size:12pt"> <br>
<p>输入新的时间间隔。 <br>
<input id="speed" onchange="updateTime()" size="20"> </span>
</p><br>
<font color="#CC3399">//*定义输入文本框，调用updateTime（）函数*//</font> <br>
<div id="div1"<br>
style="position:absolute;top:20;left:20;width:100;height:100; <br>
font-size:100;text-align:center;background-color:blue; <br>
filter:revealtrans(transition=1,duration=1.5)"<br>
onfilterchange="done(1)"><br>
<font color="#CC3399">//*设置一个层，包括它的定位、字体和revealtrans滤镜属性，同时调用Done函数<br>
改变滤镜显示样式，达到动态的目的，下面的三个层的设置内容与这个类似*//</font> <br>
<p>A</p> </div> <br>
<div id="div2" <br>
style="position:absolute;top:20;left:140;width:100;height:100;<br>
font-size: 100;text-align:center;background-color:blue; <br>
filter:revealtrans(transition=2,duration=1.5)" <br>
onfilterchange="done(2)"> <br>
<p>A</p> </div> <br>
<div id="div3" <br>
style="position:absolute;top:20;left:260;width:100;height:100;<br>
font- size:100;text-align:center;background-color:blue;<br>
filter:revealtrans(transition=3,duration=1.5)"<br>
onfilterchange="done(3)"> <br>
<p>A</p> </div> <br>
<div id="div4" <br>
style="position:absolute;top:20;left:380;width:100;height:100;<br>
font- size:100;text-align:center;background-color:blue;<br>
