脚本说明:
第一步:把如下代码加入<body>区域中
<script language="JavaScript">

function nextSize(i,incMethod,textLength)
{
if (incMethod == 1) return (72*Math.abs( Math.sin(i/(textLength/3.14))) );
if (incMethod == 2) return (255*Math.abs( Math.cos(i/(textLength/3.14))));
}

function sizeCycle(text,method,dis)
{
	output = "";
	for (i = 0; i < text.length; i++)
	{
		size = parseInt(nextSize(i +dis,method,text.length));
		output += "<font style='font-size: "+ size +"pt'>" +text.substring(i,i+1)+ "</font>";
	}
	theDiv.innerHTML = output;
}

function doWave(n) 
{   
	theText = "JavaScript";
	sizeCycle(theText,1,n);
	if (n > theText.length) {n=0}
	setTimeout("doWave(" + (n+1) + ")", 50);
}
</script>
<div ID="theDiv" align="center">

</div>



第二步:把如下代码加入<body>区域中
<body bgcolor="#fef4d9" onload=doWave(0);>
</textarea>
<SCRIPT LANGUAGE="JavaScript">

<!-- hide

function goHist(a) 

{

   history.go(a);

}

//-->

</script>

<FORM METHOD="post">
<INPUT TYPE="button" VALUE="返回" onClick="goHist(-1)" style="background-color: #8000FF; color: rgb(255,255,255)">
</form>
</center>

</body>
