实现文字渐淡显示的效果代码如下:
  <html>
  <head>
  <script>
  <!--
  function HelpArray(len){this.length=len }
  HelpText= new HelpArray(5)
  HelpText[0]="视点闪客"
  HelpText[1]="智慧无边"
  HelpText[2]="魅力无限"
  HelpText[3]="十二亿中国人的最爱"
  HelpText[4]="http://visionflash.blog.sohu.com"
  ScriptText=new HelpArray(5)
  //*定义文本数组,一共是五段文本*//
  var i = -1
  function playHelp() {
  if (i==4) { i=0 }
  else { i++ }
  div1.filters[0].apply()
  div1.innerText=HelpText[i]
  div1.filters[0].play()
  mytimeout=setTimeout("playHelp()",2500)}
  //*定义play函数,并且设置了时间间隔*//
  -->
  </script>
  <style> <!--
  #div1{position:absolute;top:20;left:20;width:480;height:200;
     font-family:行书体; color:red;font-size:40;
     font-weight:bold;text-align:center;
     filter:revealtrans(transition=12,duration=2) }
  //*设置显示转换滤镜*//
       -->
  </style> </head>
  <body onload="playHelp()">
  <div id="div1" onload="playHelp()"> </div>
  </body>
  </html>
