要完成此效果需要三个步骤 第一步：把如下代码加入到区域中 第二步：把如下代码加入到区域中 <script language="JavaScript"> var regel = 0; //row to start with var size = 20; //size of font var delay = 1200; //Delay between messages in msecs var speed = 20; //Hmmmmmm var step = 10; //Size of each step var sent = new Array() { sent[0] = "欢迎光临jojoo.net!"; sent[1] = "本站实例大多来自国外JS站点"; sent[2] = "加拿大.日本.美国.欧洲最多!"; sent[3] = "每天都有全新的JS实例提供给您"; sent[4] = "锁定本站給您最新及最好的资料"; sent[5] = "JavaScript Fairyland!"; } sent[sent.length] = sent[0];var veran = 0;var num = 0;var x = 0;//Don't change function moto(){output = "";for(letter = 0;lettersize)gr=size; output += ""+sent[regel+x].substring(letter, letter+1)+""; if(num < 0 && x==1){veran++;x=0;}}else{if(veran > letter){ output += ""+sent[regel+1].substring(letter, letter+1)+""; }else{output += ""+sent[regel].substring(letter, letter+1)+"";}}} return output;}function startmot(){if(regel==sent.length-1)regel=0;balk.innerHTML = moto(); if(veran==sent[regel+1].length){regel++;veran = 0;setTimeout("startmot()", delay);}else{ setTimeout("startmot()", speed);}} </script> 第三步：把“onload="startmot()"”加在标记里 例如：
