要完成此效果需要两个步骤 第一步：把如下代码加入到区域中 <script language="JavaScript1.2"> 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 += "" +tekst[s].substring(w,w+1)+ ""; } for(k=w;k" +tekst[s].substring(k,k+1)+ ""; } 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>

第二步：把“onload="startmotor(0)"”加在标记里 例如：
