要完成此效果把如下代码加入到<body>区域中
<script>
function selectCode(f){
document.forms[f].elements[0].focus();
document.forms[f].elements[0].select();
}
function doNada(){self.focus()}
var rate = 500;
var Color1 = "#FF0000"
var Color2 = "#00FF00"
var Color3 = "#FF00FF"
var Color4 = "#FFcc00"
var Color5 = "#00FFcc"
var Color6 = "#FF00cc"
var ColorX = "#FFcc00"
var DoIt = true
bV = parseInt(navigator.appVersion)
bNS = navigator.appName=="Netscape"
bIE = navigator.appName=="Microsoft Internet Explorer"
ok = false
var i=0;
function doTriStateRainbowLink(){
ok = true
if ((bNS && bV >= 5) || (bIE && bV >= 4)){
i++;
if (i==1) C = Color1
if (i==2) C = Color2
if (i==3) C = Color3
if (i==4) C = Color4
if (i==5) C = Color5
if (i==6) C = Color6
if (!DoIt) C = ColorX
if (bIE) BlinkLink.style.color=C
if (bNS) document.getElementById('BlinkLink').style.color = C
if (i > 5) i = 0
if (DoIt) timer=setTimeout('doTriStateRainbowLink()', rate)
}
}
function doOnOff(a){
if (ok){
if (a =="off") {DoIt = false}
if ((a =="on")&&(!DoIt)) {
DoIt = true
doTriStateRainbowLink()
}
}
}
