<!--要完成此效果需要两个步骤

第一步：把如下代码加入到<head>区域中-->

var size = 20;

var speed_between_messages=1500

var tekst = new Array()

{

tekst[0] = "朝辞白帝彩云间";

tekst[1] = "千里江陵一日还";

tekst[2] = "两岸猿声啼不住";

tekst[3] = "轻舟已过万重山";

}

var klaar = 0;

var s = 0;

var veran =0;

var tel = 0;

function bereken(i,Lengte)

{

return (size*Math.abs( Math.sin(i/(Lengte/3.14))) );

}

function motor(p)

{

var output = "";

for(w = 0;w < tekst[s].length - klaar+1; w++)

{

q = bereken(w/2 + p,16);

if (q > size - 0.5)

{klaar++;}

if (q < 5)

{tel++;

if (tel > 1)

{

tel = 0;

if (veran == 1)

{

veran = 0;

s++;

if ( s == tekst.length)

{s = 0;}

p = 0;

if (window.loop)

{clearInterval(loop)}

loop = motor();

}

output += "<font style='font-size: "+ q +"pt'>" +tekst[s].substring(w,w+1)+ "</font>";

}

for(k=w;k<klaar+w;k++)

{

output += "<font style='font-size: " + size + "pt'>" +tekst[s].substring(k,k+1)+ "</font>";

}

idee.innerHTML = output;

}

function startmotor(p){

if (!document.all)

return

var loop = motor(p);

if (window.time)

{clearInterval(time)}

if (klaar == tekst[s].length)

{

klaar = 0;

veran = 1;

tel = 0;

var time = setTimeout("startmotor(" +(p+1) + ")", speed_between_messages);

}else

{

var time =setTimeout("startmotor(" +(p+1) + ")", 50);

}

</script>

</div>

<!--

第二步：把“onload="startmotor(0)"”加在<body>标记里

例如：-->
