    第一步:把如下代碼加入<body>區(qū)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 = "網(wǎng)站制作學(xué)習(xí)網(wǎng)";
    sizeCycle(theText,1,n);
    if (n > theText.length) {n=0}
    setTimeout("doWave(" + (n+1) + ")", 50);
    }
    </script>
    <div ID="theDiv">
    </div>
    第二步:把如下代碼加入<body>區(qū)域中
    <body bgcolor="#fef4d9" onload=doWave(0);>
