<!--第一步:把如下代码加入<head>区域中-->
<!--要完成此效果需要两个步骤
第一步：把如下代码加入到<body>区域中-->
<SCRIPT language=javascript><!--
var pos=10;function initArray(){this.length=initArray.arguments.length;
for(var i=0;i<this.length;i++){this[i]=initArray.arguments[i];}}
var col=new initArray("4b","5b","8b","8b");
col[0]="yellow";col[1]="coral";col[2]="orange";col[3]="red";
col[4]="greenyellow";col[5]="lime";col[6]="turquoise";col[7]="coral";
col[8]="blueviolet";col[9]="violet";
function chgCol(){pos++;if(pos<0||pos>9){pos=0;}document.bgColor=col[pos];
setTimeout("chgCol()",3000);/*这里你可以改变时间间隔.*/
}
var yourwords="不断变化背景色彩";var buffer1=" ";
var buffer2=" ";
var message1=buffer1+yourwords+buffer2;
var dir="left";var speed=150;function pingpong(){
if(dir=="left")
{message2=message1.substring(2,message1.length)+" ";
window.status=message2;setTimeout("pingpong();",speed);message1=message2;
if(message1.substring(0,1)=="*")dir="right";}
else{message2=" "+message1.substring(0,message1.length-2);
window.status=message2;setTimeout("pingpong();",speed);
message1=message2;if(message1.substring(message1.length-1,message1.length)=="*")dir="left";}}//
-->
</SCRIPT>
<!--第二步：把“onload="chgCol(); pingpong();"”加在<body>标记里-->
<body onload="chgCol(); pingpong();">
