不断变换背景颜色
脚本说明: 第一步:把如下代码加入<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:把如下代码加入<body>区域中<body bgColor=#ffffff onload="chgCol(); pingpong();">
